Abstract
A HEALD, A METHOD FOR THE MANUFACTURE THEREOF AND A DEVICE FOR
BUNDLING SUCH HEALDS
Abstract of the disclosure A plurality of healds of thread material are in hand looms stacked on shafts for providing the shed of the loom. These healds have been produced by manually tying knots on a double-folded thread.
The manual tying is a time-wasting job and the knots, which are considerably thicker than the thread material will, when some thousand healds are stacked side by side on the shafts, form bosses which will give a non-uniform width to the stack of healds.
These problems are all eliminated by a novel heald of a textile thread material wherein the twisted or plain thread of the hitherto known thread healds has been substituted by two crochetted threads, and where each one of the knots which in the hitherto known thread healds connect the two thread parts for forming the heald eyelet are replaced by interconnecting ladders of two adjacent loops in the two crochetted threads, said novel heald being produced in a hosiery machine in a continuous length and thereupon being arranged in bundles in an automatic bundling machine.
BUNDLING SUCH HEALDS
Abstract of the disclosure A plurality of healds of thread material are in hand looms stacked on shafts for providing the shed of the loom. These healds have been produced by manually tying knots on a double-folded thread.
The manual tying is a time-wasting job and the knots, which are considerably thicker than the thread material will, when some thousand healds are stacked side by side on the shafts, form bosses which will give a non-uniform width to the stack of healds.

Description
: 1091133 The present invention refers to a heald of a textile thread and to a method for the manufacture thereof. The invention furthermore incorporates a device adopted for automatic bundling of such healds.
Healds made from textile thread are used for hand looms, and these healds have, since times immemorial, been made thereby that a thread has been tied manually into a three-part loop, which has been achieved with three knots. This is a very time-wasting job, as it is required between 1000 and 3000 healds for a loom of normal width, depending on the fabric to be woven, and as a trained heald tier can make a maximum of about 800 healds during an eight hour work day. When it is thereabove ` considered that the thread healds are sensitive to wear and therefore have to be replaced after some times~ use, is it i :
easily understood that it can be difficult to cover the demand for hand-tied thread healds. The possibility of hiring more heald tiers is also limited as the payment for the work amounts '~ to only a few Swedish ~ore pro each tied heald, which means that the daily earnings for a heald tier in Sweden will be only some ten Swedish Crowns. The work must therefore to a large . extent be made as therapy work and the like. This means that , there is always a latent need of hundreds or thousands of healds, which in turn leads to waiting time for those who wish to replace their worn-out set of healds or who wish to buy a new -loom.
The manual tying furthermore gives raise to problems regarding stock-keeping and handling as two tiers will not necessarily make uniformly tied thread healds. It is therefore necessary for heald retailers to store the production of each tier apart from that of other tiers and also to keep records over the type of healds delivered to every separate customer for making it possible to give the customers the same type of ' - 1-.
~`
` healds, having the particular properties given to them by "their own" heald tier at a later replenishment or when a worn out set of thread healds shall be replaced.
Another drawback at these hand tied thread healds is that the knots are more than twice as thick as the very thread.
As 1000 or more healds are pressed against each other on heald rods or on the shafts for forming the shed it is understood that the knots which are arranged essentially in level with each other will form bosses, which can damage the warp or -- -become damaged by th~s.
The purpose of the present invention is to provide a heald at which the abovementioned drawbacks are all eliminated and this is obtained thereby that the heald consists of two crochetted threads, which are brought alongside each other, and where loops from each one of said threads are arranged to grip into each other at predetermined spaced apart positions along the length of the two threads for forming connecting points intended , to replace the knots of the conventional hand-tied heald, ql for forming the closed heald with its heald eyelet.
The invention furthermore relates to a method for making healds of this type and this method is characterized there-by that a hosiery machine is used for crochetting two threads, which are brought alongside each other and where, in order to form the heald eyelet, loops in the two threads which are situated in front of each other are crochetted together so that one rib from each one of said loops grips into the opposite loop of the other thread.
The invention also incorporates a device for automatic bundling of healds of this type and this device is characterized mainly by a pivotably supported threading-in-lever arranged during a reciprocating movement to thread healds connected in a continuous heald length onto a threading-fork, by carrying when ` ~09~133 ~ ~
moving in one direction the length of healds to a position above the shanks of said threading-fork and to release said length of healds at its reciprocating movement in the opposite direction, a heald retainer furthermore being arranged to cooperate with the threading-fork to retain each heald when being thread upon ~ the threading-fork.
; The invention will hereinafter be further described with reference to the accompanying drawing.
Figure 1 shows a conventionally hand-tied heald in which the knots have not been tightened for the sake of clarity, Figure 2 shows in a view corresponding to figure 1 a heald according to the invention, ' Figure 3 is a view in larger scale Of a portion of the heald according to the invention and showing a connection point, Figure 4 shows how a plurality of continuously connect-ed healds according to the invention are arranged on heaid rods, ~, and Figure 5 is a schematic side view of a device for ,. , bundling healds according to the invention.
Figure 1 shows a heald 1 of a conventional hand-tied type, which consists of a single thread preferably of a comparatively soft material, which is twisted to a string 2 of suitable thickness~ This string is at three positions provided .~, , with knots 3, 4, 5 which for the sake of clarity are shown not `
` tightened and which knots have been tied manually. These knots form the side portions and the eyelet 6 of the heald. It is easily understood that a large plurality of healds arranged ; in shafts will give the bundle of healds a considerably larger thickness in level with the different knots than at the portions of the bundle which have no knots. It shall hereby be considered :.
that each knot from a general point of view is more than twice as thick as the heald thread itself and that 1000 or more : , lO9~i33 healds arranged on the shafts will of course give a highly varying bundle thickness in the longitudinal direction of the healds. The reason for using a comparatively soft material for this conventional hand-tied thread heald is that the bosses formed by the knots could damage the warp if the material was not soft and comparatively flexible. This in turn means that the heald has a comparatively short service life as the wear i will be relatively rapid due to the soft material which has a :.
low resistance to wear.
It is furthermore difficult for a not trained tier to ; tie the thread of such a heald in such a manner that the heald eyelet will be situated at the same distance from the ends of each heald of a long series of similar healds in spite of use of aids such as frames and the like.
In figure 2 is shown a heald 10 according to the :~ invention, which heald consists of two crochetted threads 11 and ~. .
~ 12 provided with connecting points 13, 14, 15 and 16, which form ;
the heald and its heald eyelet 17. As can be better seen in 1' figure 3, which shows a part of a connecting point in larger scale, the connecting points 13, 14, 15 and 16 are made in such - a manner that a loop in one of the threads 11 is crochetted to grip into a loop of the other thread 12. It is hereby formed connecting points, the thickness of which is considerably less than the thickness of the knots made in conventional manner of hand-tying. As the problem of bosses forming at the threading ' of a plurality of healds on heald rods or on shafts thereby is -~ eliminated is it possible to use a considerably much stronger thread as initial material for the heald without thereby achieving the negative effect that the warp can be twisted off by the heald.
It is hereby possible to obtain a longer service life for healds of this type as compared to conventional, hand-tied thread healds.
The crochetted heald according to the invention is '~ .
, -4-~091133 . .
preferably made in a hosiery machine, e.g., a raschel loom, which works automatically and which with simple aids can be adapted to produce healds in continuous lengths with accurate heald lengths and precise location of the heald eyelet in the heald. The problem of keeping the production of different heald-tiers in stock is hereby eliminated as all healds made with that specific machine or with a similar machine are exactly similar. The length of continuous healds is preferably provided with intermediate portions 18, which allow a free adjustability between the separate healds at the threading of the healds on ; heald rods 19, shafts or the like. An advantage at this type -of production is that the heald can be supplied as a piece-goods sold by the meter, whereupon it at a convenient time and at an appropriate place can be thread upon heald rods or shafts, which is clearly in contrast to hand-tied healds, which are tied one by one separately, and prior to the subsequent delivery must be thread upon frames. When threading healds on heald rods it can ` now and then happen that one or more healds are thread in wrong manner. As it is possible simply to cut off the heald which has been placed wrong by cutting off the intermediate parts 18 such a wrong threading is no considerable drawback being more severe for the heald according to the invention than for conventional separate healds.
It is possible by use of only one hosiery machine to produce between 25,000 and 50,000 healds according to the invention in one working day, whereby the separate healds thus ~- made can have exactly the same measures and it is furthermore obtained that thickness variations worth mentioning are eliminated as the thick knots are eliminated. Due to the simple manufacture it is also possible to make healds of this type at costs which are favourable as compared to the costs for the hitherto common convent~onal, hand-tied healds in spite of the very poor payment ~ ~09li33 `.'~
f, .
for such hand-tying.
The invention furthermore incorporates a device for, - automatic bundling of the healds according to the invention ., ~ which are made in a continuous length, and this device is :
schematically shown in figure 5.
Y( The continuous length of healds 20 is whenproduced in the: hosiery machinepreferably collectedin a container. The length of healds 20are fromsaid container (not shown) led through aknot detector fittedin a frame21 andcomprising apivotably supportedlever 22having ~ 10 an aperture,throughwhich the length of healds is thread. Said ;~?~ pivotable lever being adapted to be ~, pivotable to a position, in which it will act upon a contact rail 24. This knot detector will automatically and positively indicate , - and/or stop the operation of the bundling device if a knot ~ exceeding a predetermined size will appear on the length of > healds, which comes from the container. The length of healds 20 is from this knot detector led through a thread brake 25 and therefrom to a thread stretcher, which also acts as a knot , ~ detector and like the first mentioned knot detector consists . .
of a second pivotable lever 26 with an aperture, and which second lever cooperates with a second contact rail 27, which when acted ~ .
upon by the second lever will stop the operation of the device, e.g. by cutting off the power supply thereto. The second lever 26 is biased by a spring 28 to stretch the length of healds as " .~
,, desired. The length of healds continues from the aperture in ; said second lever 26 to a threading-in-lever 29, which is pivot-.
ably supported and adapted to make a reciprocating movement , about its support point whereby it when moving in one direction -towards the right in the figure - carries a point of the continuous length of healds positively and positions this over a threading fork 30 by releasing the said point at its reciprocating movement in the opposite direction, whereby the closed loops on each side of the heald eyelet in each heald will be thread over a fork arm '109~133 of said threading fork 30 each. When a heald thus has been thread upon the threading fork 30 in this manner a heald retainer 31 seizes the thread heald and moves it downwards, which is repeated until the desired bundle size (e.g. 100 healds/
bundle) has been reached.
., .
By aid of this bundling device is it possible to make the production of healds according to the invention highly automatic.
The invention is not limited to the embodiments shown in figures 2-5 and described in connection thereto but it can be modified in a plurality of different manners within the scope of the appended claims.
