Abstract

Knitted trimmings with regular or fully-fashioned edges according to the invention are used to be attached to a garment, e.g. a pullover. They are characterized by one or both selvedges (2, 3) in plain fabric knitted in a sandwich form. Methods according to the invention for producing such strappings can be carried out on double-bed flat knitting machines with one or several operating yarn carriers, the fabric being knitted with the wales extending lengthwise of the trimming. In accordance with these methods, there is at least at one side of the trimming the laterally open V-shaped edge or edge in sandwich form with fully-fashioned selvedges of the individual sandwich parts of the "V". These knitted trimmings may be attached by sewing to the edge of a garment in a simple and neat manner without preparation, such as e.g. steaming. <IMAGE>

Description

SPECIFICATION A knitted sandwich strapping with selvedge edge The present invention relates to a knitted strapping with one sandwich edge which is Vshaped when viewed in cross-section and formed of tubular fabric with selvedges.

By fully fashioned edges or selvedges there is to be understood knitted tubular fabric selvedges.

What are to be understood by regular sandwich parts or sandwich edges are lateral edges which have been produced by knitting techniques.

Strappings will be knitted on double-bed flat knitting machines in any length and with varied knitting methods. Among others they are used to be attached to trim garments such as, for example, pullovers. They are inserted at appropriate places where elasticity is not necessary or only little elasticity is necessary. These strappings are either used as double-trimmings or are attached as a single trimming on one side of the garment. The attachment to the garment is effected by a sewing method.

From US-PS 1 054 233 knitted strappings are already known as knitted trimmings having one starting or one ending sandwich edge (seen in cross-section) (a V-shaped cross-section at their starting or ending edge). The edge of the garment to be attached is inserted into this edge area and then secured by a sewing operation. But such trimmings or strappings can only be produced in the length (width) of the operating needle-bed or the double-bed flat knitting machine.

Consequently they cannot be produced i.e. knitted endlessly.

An object of the invention is to provide a knitted strapping to be attached to both sides of a garment, which may be knitted in any length and which need not be specially prepared for the subsequent treatment, e.g. by steaming.

The object of the invention is achieved by a knitted strapping with selvedges (regular edges) to be attached to a garment, characterized by the fact that one or both selvedges are knitted in tubular fabric in a sandwich form. In other words, a V-shaped knitted edge is produced by a tubular knitting method at one or both sides of the strapping. In such a strapping, both the sandwich edges resulting at the V-shaped edge as well as the other lateral edge are knitted with fullyfashioned selvedges i.e. are regular, and produced by knitting techniques. Such strappings can be knitted on double-bed flat knitting machines with the knitting method of the invention in any length and in several sections as well.

These methods according to the invention for the production of such strappings on double-bed flat knitting machines are characterized by the features of claims 2, 3, 4, 5 or 6.

In all these knitting methods according to the invention, the laterally open, V-shaped edge is formed at least on one side of the strapping with regular closure edges of the individual sandwich parts of the "V". These knitted strappings can be sewn onto the edge of a garment simply and neatly without any prior preparation.

All methods being described hereafter are using the possible knitting methods of double-bed flat knitting machines with one or more yarn-carriers, to change over from one needle-bed to the other in one particular course and to bring back the yarn to the starting course in a reversed knitting operation for the next course. In operating in this way, it will be obtained, by the different knitting methods, that even in the adjacent strapping region there will be no bigger lengths when forming the sandwich or V-shaped lateral edge from tubular fabric (loops).

The invention will be described further, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a diagrammatic principal view of a knitted strapping with one V-shaped lateral edge or sandwich selvedge, Fig. 2 is a cross-section of the strapping of Fig. 1; Fig. 3 is a symbolic illustration of the strapping of Figs. 1 and 2 and illustrating the loops (stitches) in 4 continuously knitted courses in one and one rib - 1:1 needles -- (interlock method in the main part), Fig. 4 is a symbolic illustration of the strapping of Figs. 1 and 2 having loops comprising 4 courses in full cardigan in the main part of the strapping, Fig. 5 is a symbolic illustration of the loops of the strapping of Figs. 1 and 2 formed in tubular fabric in the main part of the strapping; and Fig. 6 is a symbolic illustration of the loops of the strapping of Figs. 1 and 2 showing 4 continuous courses in one and one rib (1:1 needles) which are knitted with two yarn carriers.

In principle a strapping to be endlessly knitted according to the invention as in Figs. 1 and 2 comprises an (edge) area 1 in any suitable knitting type i.e. any qualified fabric with a regular lateral edge i.e. fully fashioned selvedges (in this case the right side) and a V-shaped edge or sandwich edge in tubular fabric knitted in a sandwich form, the point of commencement of the sandwich or angle point of the V-shaped edge being referenced 4.

The outer edges of the sandwich parts or selvedges 2 and 3 are also fully-fashioned and thus formed by knitting techniques, i.e. are regular.

Such a strapping can be knitted on a doublebed flat knitting machine with one operating yarncarrier according to the following knitting operations (symbolically shown in Fig. 3); namely: 1 course (row) (a) one and one rib (1:1 needles) of numbers of welts according to the width of the strapping (1 ) which changes over on the first needle bed into a number of tubular welts according to the width of the edge (2); 1 course (b) in reverse knitting direction of an identical number of tubular welts as in the preceding course which changes over into the corresponding number of welts in one and one rib (1:1 needles); 1 course (c) one and one rib (1::1 needles) of numbers of welts according to the width of the strapping (1) in reverse knitting direction compared with the preceding course (b), and this on the respective adjacent needle, which changes over into a number of tubular welts according to the width of the edge (3) on the second needle bed; 1 course (d) in reverse knitting direction with an identical number of tubular welts, which changes over into a corresponding number of welts in one and one rib (1:1 needles).

The arrows shown at the courses a, b, c, d indicate the knitting direction of the machine.

According to such a method, the actual strapping fabric section 1 is formed by applying the Interlock-method. By applying this method, less yarn will be used for this section to be knitted.

The tubular welts of each course form the sandwich parts of the V-shaped edge or sandwich edges. At the angle point 4 of this edge they are reversed again with their yarn, in order to build the selvedged edges so that the sandwich edges are regular according to knitting techniques.

Another method for the knitting of a strapping illustrated in Figs. 1 and 2 is effected by the following continuous knitting operations which are repeated as often as is desired depending upon the length of the strapping required. Four of such courses are shown in Fig. 4, namely: 1 course (a) full cardigan of numbers of welts according to the width of the strapping 1 changing over into a number of tubular welts on the first needle bed according to the width of the edge 2; 1 course (b) in reverse knitting direction of the same number of tubular welts, changing over into a corresponding number of welts in full cardigan; 1 course (c) full cardigan of number of welts according to the width of the strapping 1 in reverse knitting direction compared with the preceding course (b), which changes over into a number of tubular welts on the second needle bed according to the width of the edge 3;; 1 course (d) in reverse knitting direction with an identical number of tubular welts, changing over into a corresponding number of welts in full cardigan.

In this method of knitting a strapping, the necessary reduction of loops in the edge region i.e.

the welts is obtained by applying full cardigan.

Hereby as well the tubular welts knitted on the two needle-beds with different knitting directions form the sandwich area with selvedges.

A method of producing a strapping, as shown in Fig. 5, is that such is knitted all in tubular fabric i.e.

with a tubular loop knitting method in which the following continuous knitting operations are repeated as often as desirable.

1 course (a) tubular loops in a number of welts in the complete width of the strapping 1 and as the edge 2 on the first needie bed; 1 course (b) in reverse knitting direction on the first needle bed of a corresponding number of tubular welts for the edge area 2 changing over to the second needle bed into a number of tubular welts according to the width of the strapping 1.

1 course (c) on the first needle bed of a number of tubular welts according to the width of the strapping 1 in reverse knitting direction compared with the preceding course (b), which course changes over to the second needle bed into a number of tubular welts according to the edge area 3; 1 course (d) in reverse knitting direction on the second needle bed of a number of tubular welts in the whole width of the strapping 1 as well as the edge 3.

Strappings with sandwich selvedges can also be knitted on double-bed flat knitting machines with two operating yarn carriers using the appropriate sequence of the knitting operations of the above described methods. Both yarn carriers -- which are spaced from each other are always operating simultaneously on one needle bed, whereby both of the courses are knitted in the same direction. Such a knitting operation is shown in Fig. 6. Compared with the view in Fig. 3, both yarn carriers are at first working the courses a and c in the same knitting direction and then subsequently the two courses b and dor dand bin the reverse knitting direction.

Strappings with edges in a sandwich form i.e.

V-shaped edges on both sides can be knitted on knitting machines with at least two yarn carriers on a double-bed flat knitting machine, whereby the knitting operations as in Figs. 2 to 5 are accordingly used. Thereby the first yarn-carrier consequently operates the tubular course on the first needle bed, while the second yarn carrier is operating the tubular course on the second needle-bed. Thereby the courses a and c or respectively b and d which are knitted in the same direction according to the width of the selvedges will form a number of tubular welts (i.e. are preceded by a number of tubular welts corresponding to the width of the lateral edge) so that the other edge of the strapping also has a selvedge in a sandwich form i.e. V-shape.

The described methods which are symbolically illustrated may also be carried out appropriately on hosiery machines.
