Definitions
- the present invention relates to the textile industry and in particular to a new comb device and its use as a movable warp beam-comb connection which can be inserted and removed as a unit in a weaving machine as soon as the thread of the warp beam has ended.
- the warp of the fabric in process is supplied by two huge warp beams, on which as many threads are wound as there are in the warp of the fabric to be woven. These threads are alternately moved back and forth in the weaving machine between two positions with the aid of a small dobby, a jacquard machine or an eccentric system, so that a separation is created through which the weft insertion or the weft insertion takes place. This separation is known as a shed. After each compartment and every weft insertion, a drawer hits the weft in the weaving machine in order to compress the fabric. So you continue until the threads of the warp beam are over.
- Another object of the invention is to reduce the movable elements in the weaving machine by removing the shedding device and all those elements which are necessary for its movement.
- Another object of the invention is to eliminate the fixed comb of the weaving machine by replacing it with an comb that is easy to insert and remove.
- Another object of the invention is to provide a warp-comb connection which is prepared outside the weaving machine and which undergoes repeating and is brought to the weaving machine as a unit and which is inserted into the weaving machine every time the weaving chain is finished .
- An additional object of the invention is to minimize the time lost by repeating the comb in the weaving machine by doing this outside of the weaving machine while it remains in operation.
- An advantage of the invention is that energy savings and repairs are made possible by reducing the number of moving parts in the weaving machine.
- the shed is formed at a lower tension of the threads, as a result of which significantly fewer threads of the warp break, and the work involved in connecting the threads and the associated loss of time are significantly reduced.
- the invention is based on the provision of a new comb with a series of passages or gaps which are alternately between the teeth of the comb. Some selected rounds are provided with a corresponding tip for the specialist training.
- the comb has a flat side and a side on which there is a projecting curvature for each tooth.
- the curved area extends a sufficient distance so that when the comb is moved back and forth during shed formation, the curvature reaches the weaving point of the weaving machine and the weft thread beats in a striking movement, which then continues in the opposite direction, and so on.
- the comb does not have these cantilevers, which perform the striking in a combined movement of approach and distance from the point of entry of the shot while moving from one shedding position to another on a path called "lying V" because of its similar structure .
- This comb is removably received in interacting elements which are located in the binding of the drawer, the connection between these elements and the ends of the comb being created by securing elements, preferably of the bolt type.
- the warp beams which are normally processed with a warping machine separate from the weaving machine, are provided with the respective comb in a suitable station, the conventional repeating being carried out in a station located in the weaving machine, so that a warp beam-comb connection is created.
- This connection is lifted into a transport position and from there into a position on the weaving machine, from which it is lowered onto the corresponding supports which receive the warp beam. Now you start to install and fix the comb on the corresponding holder on the binding of the drawer, after which you start the weaving machine to produce a fabric.
- the warp beam and comb are removed by conveying the warp beam to the transport device and inserting a new warp beam with comb, and while the weaving process starts again, the empty warp beams are brought to the warp warping station To start the cycle again without losing time by repassing the comb in the weaving machine or by tying the threads of the new warp to the threads in the weaving machine.
- FIG. 1 shows the first embodiment of the comb 10) which has a plurality of passages 30 which alternate with the "teeth" of the comb.
- the shape of the comb 10 can clearly be seen in FIG. 1 and looks like a plate which has a flat rear side 40 and a front or working side, the upper edge part 32 of which is straight and parallel to the rear side 40. This upper edge part extends to the ends, where a vertical wall 15 is provided as the outer boundary, in which there is a series of bores 16 (two of which are shown here).
- a front-side projection for each of the teeth 33 begins, which changes into a convex curvature, in which the point with maximum circumferential extent is defined with 34 with respect to the plane of the parts 32 and 15, from where the curvature reverses at 35 to return to the lower part 36 level.
- the comb 10 has no projections on the working side, so that it looks like a plate on both sides.
- the passages or gaps 30 of the comb 10 according to the invention can be equipped with any of the two types of tips which are shown in FIG. 1A.
- the first tip type 37 consists of a transverse lamella which extends approximately to half the height of the gap 30 between two teeth 31 lying next to one another, a thread 38 being shown on the tip 37.
- the other type of tip 37a consists of a plate which fills the space up to a certain height of the gap 30 and is located between two teeth 31 lying next to one another.
- the thread 38 is located in the space left by this second type of tip.
- each of the two types of tips can be used alone on the whole comb, although in the figure both types are shown on the same comb, that is, they do not necessarily have to be combined, as is the case here because of the Is shown briefly. It is further clarified that the tips are shown alternately arranged in each passage or gap 30, but can be arranged in any other appropriate and chosen distribution.
- the vertical wall 15, which closes the end of the comb 10, is arranged so that it can be received in an insertion device 11, a comb receiving element, which preferably in the binding of the drawer (not shown) Loom should be installed.
- This receiving element consists of a running rail 12 which extends from its upper end to its lower end and is delimited by two arms 12a and 12b, each of which has a series of through bores 13, 14 which are arranged so that they are connected to the holes 16 of the wall 15 match and the comb can remain in its working position in the weaving machine (not shown).
- the comb of the first embodiment of the invention is arranged so that it can be moved back and forth between the two shedding positions, together with the device 11, in the vicinity of the weaving point or the fabric production in the weaving machine. Its position is chosen so that each time the comb 33,34,35 moves from one shed position to another, the parts will strike in the shed just created (that is, after the weft or wefts have been shot) to compress the tissue.
- the comb 10 fulfills its first function when moving from one position to the other, namely that of opening threads for shed formation, while the comb 10 fulfills its second function when passing through the central position by striking the tissue that is currently in motion is woven.
- the comb 10 fulfills its two functions thanks to a movement which describes a lying V, a movement of approaching and distance from the point of the weft insertion being combined with a movement of the transition from the first to the second position of the shedding , so that the point of maximum approximation with the transition of a given point of the Comb collapses on the fabric surface.
- One of the projections of the present invention results from the position of the comb of the invention in the weaving machine. This position is easier to understand when comparing Figure 2A with Figures 2B and 2C.
- FIG. 2A shows a warp beam "J", in the continuation of which there is a shedding device "C", a shop comb P being located at a certain distance from this device and on the opposite side of the warp beam J.
- the threads of the warp that are supplied by the warp beam J are separated by the device C above and below the fabric surface "T" at a distance "D” to provide sufficient separation "S" for the weft insertion at point "X" receive. Since the comb moves to approach and distance from point X, the distance between device C and point X is very large. The distance is also so large because the threads have to be separated to allow the weft to be inserted. As a result, the threads are subjected to a very great tension, which often leads to thread breaks.
- FIGS. 2B and 2C which complement one another for the purpose of displaying the two shed formation positions, there is firstly no device C and secondly the distance between the comb (which also has shed forming function) and the point X is very short, which is why only a very small one There is a shift in one direction and the other in relation to the fabric surface, which is expressed in a significantly lower thread tension compared to conventional technology. Thread breaks with all their consequences are practically excluded.
- the latter advantage is due to the fact that one of the shed positions is a natural one, that is, a non-tensioned thread position, so that the thread only one of the two positions (that of Figure 2C) is an easy one Have tension.
- the comb 10 can be easily and quickly installed in the device 11 (and from there in the weaving machine), for example with the aid of bars (not shown) which are guided through the continuous bores 13, 14 and 16, the comb can be easily and quickly removed and reinserted, it being no longer necessary for the comb to be permanently installed in the weaving machine.
- the formation of a Kettbaum-Kamm connection which is similar to that shown in FIG. 2, is therefore considered.
- warp beam-comb connection is intended in this description and in the claims to denote a unit which preferably consists of two warp beams, the threads of which are drawn into one and the same comb; however, a unit with a single warp beam can also be called the threads of which are drawn into one and the same comb.
- These warp beam-comb connections can be formed outside of the weaving machine, which is in contrast to everything previously known.
- a connection 20 of this type consists of at least one warp beam 21 (preferably two warp beams) onto which a large number of threads 23 are wound during the warping (winding) and of a comb 10 through which the threads 22 have been repassed (drawn in) .
- This work is carried out outside the weaving machine, so that the weaving machine does not have to be taken out of operation while the threads are being drawn in.
- the warping of the threads to form a warp beam then takes place in a first warp thread warping station (see FIG. 4), either according to the sectional warping method or with the direct method of warp thread warping, both of which are known from the art.
- a first warp thread warping station see FIG. 4
- the transition is made to a comb drawing-in station, where one of those drawing-in machines which exist on the market is used to repass the comb with the threads with a dual function according to the invention.
- the use of a special pull-in station has significant advantages, which can be summarized as follows:
- the pull-in and / or tying-on machine does not have to be from one side the other is pushed, thereby avoiding both delays and damage to the machine;
- the operator of the machine has a more comfortable and suitable workplace, which is reflected in greater efficiency and speed, and
- the time lost during repassing and tying is reduced considerably (it is no longer necessary to tie the threads).
- the warp beam-comb connection is raised to the transport position. This is preferably done using pulley blocks or similar devices (not shown) mounted on top of a rail system, such as rail 60, shown schematically in Figure 3, from where the transport takes place to that point which is related has been mentioned with the pick-up device of the warp beams of the weaving machine and is also shown in general in FIG.
- warp beams are lowered into the position provided for the warp beam 20 in the next step of the block diagram of FIG. 4, and as soon as the warp beam has reached its position, the comb is mounted on the holding device 11 (FIG. 1) and the weaving work begins Manufacture of a fabric.
- the comb is decoupled from its position in the weaving machine, the empty warp beams are lifted to the transport position by the pulley, at which point another pulley can be in the down position to use a different warp beam, fix a new comb and continue the weaving process while the empty warp beams are brought to a warp warping station where the cycle starts again.
- the use of two Kettbaum-Kamm connections is considered, so that the weaving process is never stopped, except for brief moments during the change of connections.
