Embodiment Construction

[0024] Hereinafter, a tape processing tool according to an embodiment of the present invention will be described in detail with reference to the drawings. In addition, although the cutting object of the sheet|seat cutting apparatus of this invention is a sheet, it is substantially the same as a tape processing tool.

[0025] First, refer to figure 2 (a) and (b) illustrate the tape 10 cut by the tape processing tool of the present invention.

[0026] figure 2 The belt 10 shown in (a) and (b) is a long sheet with a predetermined width, and is specifically a belt used for conveying apparatuses, such as a belt conveyor and a printing machine. like figure 2 As shown in (b), the belt 10 is composed of a core material 10a and outer layers 20b laminated on both surfaces of the core material 10a. The core material 10a is formed of canvas, non-woven fabric, etc., and the outer layer 10b is formed of natural rubber, various synthetic rubbers, or thermoplastic elastomers or thermoplas...

Abstract

Provided is a sheet cutter for use, for example, in a belt working apparatus, comprising a base (2) for placing a belt, a die holder (4) for holding Thompson die at the bottom thereof, a stripper plate (3) capable of holding down the belt at a lower position and vertically movable above the base, the stripper plate being provided with a slot through which a cutting blade of the Thompson die passes, a cam plate supported by a rotatable pin supported by the base, the cam plate being provided with a cam surface that urges the die holder downward upon rotation, an operable member (6) including a lever that rotates the cam plate, a means for biasing the stripper plate upwardly and a stopper for limiting an upward motion of the stripper plate.

Description

technical field [0001] The present invention relates to a piece cutting device and a belt processing tool for cutting a piece such as a belt into a predetermined shape, and more particularly to a belt splicing tool for forming an endless flat belt by butting ends of a long flat belt. Background technique [0002] In order to butt the ends of the belt smoothly and firmly, finger joining may be employed in which the ends of the belt are cut and processed into a zigzag shape and then butted together. The finger joint has the advantage of increasing the contact area between the ends and increasing the strength of the butt joint. Patent Document 1 describes a flat belt joining method based on such finger joining. According to this joining method, the butted ends are processed into serrations respectively, and they are butted in a meshing manner (refer to figure 2 ). [0003] Patent Document 2 discloses a motor-driven shearing machine. This shearing machine is a device that ra...
