Description

Machines for cutting double and similar fabrics, such as velvet, are already known as the main working body, and an endless band knife moving in a PLANE: weaving and parallel to the rollers feeding it. Such masks are also used to cut unevenness from felt, leather, etc.

The proposed tooling for obtaining figured and profiled blanks and cotton wool layer or similar materials in machines for cutting fabrics with tape: knife- has a distinctive feature that to communicate the movements of the wool relative to the blade of the ribbon knife before cutting the MI of the corresponding areas of wool, the appropriate preparation has been used a concave armor, rigidly reinforced on the surface of the shaft. The device, in particular, can be used to make halves of the base of an ogoo wool boot made of wool and the like.

In FIG. 1 is a schematic front view of an exemplary form of the device;

FIG. 2 - VI1D on the side of the machine for the longitudinal cutting of fabric, felt and the like Material with the proposed tooling; FIG. 3 is a longitudinal section of a part of the device according to fit. one.

The fixture is made in Vlde of a convex-concave plate 9, the outline of KiOTOporo corresponds to the shape of a half; basics of felt boots and the like. The template 9 is rigidly attached to the middle working part of the surface of the pressure shaft 3 of a known mask for longitudinal cutting of the weaver in its plane. This machine encloses the clamping valz equipped with adjustable screws with screws with shtruvala 1 in the direct lateral beds 2, supports. shaft 10 has an elastic, e.g., rubber-sheath, interacting with a series of rings 8 that are aligned along one axis and interacting with the material, P, extending between the pressure shaft, 3 and the rings 8. For transferring to rotation pressure roller 3 from the drive shaft with the leading rivet 6 are intended shchestren 5 and 4, reinforced

on a common roller, of which gear 5 is coupled with gear b, and gear 4 - with gear 7 of the drive shaft 3. Along the lower forming shaft of the drive shaft: 3 there is a lever of a moving endless belt knife 12, which cuts the material, usually along its middle surface.

The operation is expressed in that when pressing the 11 convex m-eats 13 of the template 9 (FIG. 3) on the cotton, the corresponding rings 8 will move downward, the latter will be pressed into the facing of the shaft 10, and the blade of the band knife 12 will cut off co-woven areas of cotton wool. The concave spots 14 of the template 9 will not exert pressure on the cotton 11, and the blade of the ribbon knife 12 will cut the wool somewhat closer to the bottom surface of the wool or even not at all to cut it, in view of the ability of the wool to somewhat bulge upward from its own elasticity. Corresponding to the selection of the high convex and concave parts of the template 9, it is possible to achieve from the cotton wool M finished, i.e., cut objects, for example, halves of the foundation of a low-loaded boot with lower edges, necessary for splicing both halves of the base into the half-finished boot.

The subject matter of the invention.

A device for producing figured and profiled blanks from a layer of cotton wool or the like in machines for cutting fabrics, felt and other materials equipped with a band knife, characterized in that it is made in the form of a corresponding preform of a convex-concave template rigidly fixed on the surface- clamping shaft 3 and: intended for communicating the movements of the wool, etc., in contrast to the blade of the band knife 12, in order to cut the corresponding sections of the wool by the latter.
