Problems solved by technology

In addition, if tension is applied to the sheet material while being conveyed, there is a risk of reaching damage in a wrinkled state
If the sheet material is deformed or damaged, there is also a risk of misalignment, etc. when stacked on the conveyed fabric

Embodiment

[0037] figure 1 The schematic structure of the meandering prevention apparatus 1 of a sheet material which is one Example of this invention is shown schematically. figure 1 (a) shows the structure seen from the front, figure 1 (b) means from figure 1 (a) Structure seen by section line B-B.

[0038] The meandering preventing device 1 of a sheet material includes a winding roller 2 and a feeding roller 3 . The sheet material 4 moves between the winding roller 2 and the pay-out roller 3 . The direction in which the sheet material 4 moves can be switched between the direction from the delivery roller 3 to the winding roller 2 and the direction from the winding roller 2 to the delivery roller 3, and can also be reciprocated multiple times by repeated switching. The sheet material meandering preventing device 1 prevents meandering when the sheet material 4 moving in the direction from the delivery roller 3 to the winding roller 2 is wound up by the winding roller 2 .

Abstract

The invention provides a sheet material crawling prevention device which can prevent crawling of a sheet material in moving, especially on a winding side. The sheet material crawling prevention device (1) can prevent crawling especially generated in a process of winding a sheet material (4) moving to a winding roller (2) from a discharging roller (3) by the winding roller (2). The winding roller (2) can slide in a direction of a shaft (2a), thus if the sheet material (4) crawls, the winding roller (2) also shifts in the direction offset by crawling, generating no winding crawling on the winded sheet material (4).

Description

technical field [0001] The present invention relates to a meandering prevention device for a sheet material which achieves meandering prevention when winding a moving sheet material. Background technique [0002] Conventionally, when using a sheet material such as cloth as a cloth cut into parts by a cutting machine, since it is laminated in a multi-layered state, it is cut from a drum roll of the cloth to a certain length and then laminated. device (for example, refer to Patent Document 1). In such an apparatus, the operation of feeding out the sheet material on which the cloth is placed and being conveyed from one of the plurality of rollers to be wound by the other, and feeding out from the other and being wound by the other is repeated. If the sheet material meanders while moving between the rolls, a winding deviation occurs on the roll on the winding side. If the winding and unwinding are repeated while switching the moving direction of the sheet material, the degree ...
