41 Claims.

This invention relates to a new method of weaving metal fabric and particularly to a machine for weaving metal fabric in accordance with my new method.

5 My new method of weaving is an improvement over that contemplated in producing the metal cloth disclosed in Grebe Patent No. 2,078,940 wherein filler ribbons or Wires of elongated crosssection are woven in crosswise of the cloth by an over and under weave of longitudinally extending pairs of warp wires, the ller ribbons or strands of elongated cross-section 4being positioned with their long sides at an angle to the plane of the cloth. In fabricating metal cloth 5 in accordance with the teaching of the Grebe patent, it has been observed that the resulting material upon being subjected to the common stresses and the resultant distortion does not always return to its normal shape. More speci- ;0 cally, I have found that relative movement occurs between the Warp wires of the pairs of warp wires in the area where these wires. cross each other. This area is located between adjacent filler ribbons or wires. I have discovered that L5 in this type of metal fabric the warp wires must be locked or fastened together against relative movement in this vital area if a fabric is to be produced having the requisite properties for universal acceptance.

0 It is an object of this invention to provide a method of weaving a metal fabric or cloth composed of a plurality of warp strands extending lengthwise of the cloth and a plurality of ller ribbons or strands of elongated cross-section ex- `5 tending across-the fabric with the long sides thereof substantially parallel and disposed at an v angle to the plane of the cloth by virtue of which method of weaving a cloth results that will withstand the common forces to which it is subo jected without becoming distorted beyond return of its constituent elements to their normal relative positions. More specifically it is an object to provide a method of weaving the instant type of cloth that will result in fastening to- 5 gether the warp wires of the respective pairs in the area of their crossingV between successive filler ribbons'or strands of elongated cross-section, whereby to impart to the cloth the' requisite qualities above enumerated and thus render 0 it more useful in such broad applications as in the insect screen field, in the field of shading devices, and in the gas and liquid contact field as well as in equivalent relations.

It is an object of this invention to provide 5 a weaving machine for producing metal cloth of any desired size of mesh in accordance with my improved method.

It is a further object to provide a machine of this type that is capable of weaving a plurality of pieces of cloth simultaneously. i 5

A still further and more specic object is to provide a weaving machine particularly adapted to weave fine mesh fabric of the present type possessing the above desired properties.

A more specific object of this invention is to 1o provide in a weaving machine of the present class, a new arrangement of weaving head, warp wire supply means and filler wire supply means having a new mode of coaction.

It is a still further object to provide in a weaving machine of the present class, a novel arrangement of e-lements deiining acomb assembly and operating means therefor including a new vmode of coaction between these elements.

It is a further and more specific object to provide in a weaving machine of the present class, a comb and quill assembly having a new and improved mode of coaction whereby ribbon elements or filler strands of elongated crosssection may be woven in at any desired angle to g5 the plane of the cloth.

A still more specific object is the provision of a new and improved quill and rack assembly whereby the respective quills are rotated simultaneously in a continuous direction at successive intervals to produce a symmetrical line of twists without. releasing driving contact between the rack and the quills.

Another specific object is the provision in a weaving'machine for weaving iine mesh fabric of 35 an improved quill for feeding a pair of warp wires oif the nose thereof constructed particularly with-reference to the problem of forming as large a shed as possible for the reception of a side injected ribbon or filler strand of elongated o cross-section.

Included among the special objects of this invention is the provision of an improved arrangement for supplying warp wires to the quills whereby to prevent the twisting together of warp @5 wires behind their respective quills While atthe same time subjecting the warp wires to a slight feeding tension. More specifically it is an object to provide a special arrangement of conduits for maintaining the warp wires separated and for leading the same from their respective supply spools to the rear of their respective quills. Again more specifically, it is an object to provide a special arrangement of turntables and-'warp supply spools mounted thereon whereby to den liver the warp wires'through the conduits to the quills without twisting the warp wires together at the rear of the quills, notwithstanding the rotation of the quills for twisting the wires of each pair together adjacent the forward end thereof in locking a filler strip in place.
