CUTTING DEVICE FOR CUTTING THE SELVEDGE TUBE OF A FABRIC Filed Oct. 30, 1961 United States Patent 3,237,655 CUTTKNG DEVICE FOR CUTTING THE SELVEDGE TUBE OF A FABRIC Kuno Felder, Mozartstrasse 8, Haan, Rhineland, Germany; Sicfiried Wittwer, Kampstrasse 71, Haan, Germany; Rolf Bogershausen, Am Kauerbusch 9B, Haan, Germany; and Bruno Kreitz, Bahnhofstrasse 75, Haan, Germany Filed Oct. 30, 1961, Ser. No. 148,357 2 Claims. (Cl. 139-291) The present invention relates to a method of producing selvedges on fabrics manufactured on shuttle-less weaving looms, in which the selvedges are first formed as tubes and then each tube is flattened and cut at its two edges so that the lower web of the tube remains on the fabric base.
If the tube-shaped edge-portions were retained, this would lead to considerable difficulties in the equipment, in particular in the finishing process. The thickness of this selvedge tube corresponds to double the thickness of the main fabric.
In accordance with the present invention the selvedge tube is cut by means of a suitable cutting device so that only one-half of the tubular part forms the selvedge.
The lower half of the selvedge tube is cross-woven in a known repp and taffeta weave and the upper half is cut oil in accordance with the invention by a cutting device on a Jacquard loom as the fabric and selvedge tube are progressively woven. Consequently, a practical way of removing the upper part of the selvedge tube is provided, making the separation continuous and automatic without requiring particular attention or use of special cutting means, separated from the loom.
The cutting device according to the invention comprises a base plate provided with a finger-like projection serving as a stretching and flattening member, and a cover plate between which cutter blades are arranged at the base of the finger-like projection.
In order that the invention may be more readily understood, a preferred embodiment thereof is described below in conjunction with the accompanying drawing in which:
FIG. 1 shows an embodiment of the cutting device of the invention in plan view;
FIG. 2 shows an end elevational view of the device of FIG. 1; and
FIG. 3 shows a side elevational view of the device of FIG. 1.
A circular selvedge tube is first formed in known manner and consists of an upper part or web and a lower part or web, which together have double the thickness of the main part of the fabric.
In order to bring the thickness of the selvedge to that of the fabric, the selvedge tube is flattened and severed along lateral lines or edges by means of a cutting device, so that the upper web can be removed from the lower web.
In order to provide the remaining lower web of the flattened formerly circular web with the necessary strength and to make it free of wrinkles, a particular crossing or laying of threads is used. For example, this can be effected by making the upper part of the circular web to be cut off as a taffeta weave and the remaining lower part of a cross-woven repp and taffeta weave. The upper and lower parts are different from each other due to this type of weaving so that the remaining lower part is a tightly woven smooth web, which has the necessary strength to serve as selvedge.
The device shown in FIGS. 1-3 is used as the cutting device. It has a base plate 1 and a cover plate 2 which are connected together and to the breast beam of the loom by screws 3 which extend through slots formed in the plates 1 and 2. These slots are elongated in direction of the width of the material to be cut, so that the cutting device can be adjusted relative to the breast beam to permit cutting of materials of different widths. The base plate 1 is provided with a finger 4- which serves as a stretching member when inserted into a selvedge tube and flattens the same to form to superimposed webs connected along the sides.
The cutting device is fastened to the breast beam 7 of a Jacquard loom. The stretching member 4 is inserted into the selvedge tube 8, so that the slanted cutting edges 5' and 6 cut the sides 8a, 8b of the newly woven part of the selvedge tube 8 according to the movement of the fabric and selvedge tube toward the cloth beam. The lower part or web remains attached to the fabric 9 whereas the upper part or web 8d is entirely removed from the lower part 80 in the form of a strip.
We claim:
1. A cutting device for cutting a selvedge tube on one side of a fabric being woven in a working plane on a loom having a breast beam, comprising a support member and integral therewith a flat stretching member located substantially in the plane of said fabric and having two lateral edges, said stretching member being adapted to be inserted into the selvedge tube for transversely stretching the selvedge tube so that the same forms along the length of said stretching member two parallel webs connected to each other along longitudinal fold lines formed along said lateral edges, one of said webs being substantially located in the plane of said fabric; a pair of cutting means attached to said stretching member and laterally projecting from said lateral edges to engage and cut the selvedge tube along said fold lines; means for attaching said support member with said stretching member and cutting means to the breast beam of the loom on which the selvedge tube and said fabric is being woven so that as said selvedge tube and said fabric move toward the breast beam, said pair of cutting means cut off the other of said webs along said fold lines whereby said one web forms a single ply selvedge on said fabric; and means for adjusting the position of said support member and of said stretching member and cutting means relative to said breast beam so as to be useable for fabrics of different widths being woven on said loom.
2. A cutting device as set forth in claim 1 wherein said lateral edges of said stretching member are parallel.
