Title: Sheet dividing taking-up apparatus
Inventor: KATAOKA HIROSHI
IPC: B65H18/16
Filed: 1978-10-26
Abstract: PURPOSE: To perfectly prevent engagement due to the overlapping of the contiguous sheet edge in taking-up, by contracting the lateral width of each divided sheet as wave-shaped section by means of a touch roller and taking-up the sheet after forming a gap between contiguous sheets.  
     CONSTITUTION: In the taken-up product manufacturing apparatus, one band- shaped sheet is divided into several parts by a slitter, and the divided sheet is allowed to advance straight on, and after taking-up the sheet onto the same taking- up shaft, sheet is drawn out from the shaft. An annular projection part 6 and a concaved groove part 7 are arranged alternately in the axial direction on the peripheral surface of a touch roller 3 which takes-up the divided sheet having been sent and pushes the sheet onto a taking-up shaft 2 or onto the sheet roll So rolled and allows the sheet to be rolled-in. Thus, on the peripheral surface of the touch roller 3, uneven part is formed, and divided sheet S is allowed to be rolled-in by the wave-shaped section, and thus the sticking due to the engagement between contiguous sheet rolls So in taking-up divided sheet S onto the same taking-up shaft 2 can be prevented.
