Title:
APPARATUS AND METHOD FOR PRODUCING RUBBER SHEET
Document Type and Number:
Japanese Patent JP2017001316
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make the amount of bank uniform in the axial direction of the calender rolls, thereby improving the quality of a rubber sheet.SOLUTION: In an apparatus 10 for manufacturing a rubber sheet, a continuous rubber material M1 is supplied onto a supply conveyor 18 in a meandering state by supplying the continuous rubber material M1 onto the supply conveyor 18 while moving rubber supply means 20 in a reciprocating manner in a roll axial direction J of calender rolls 14, 16. The rubber supply device 20 has: a full width moving mode in which the rubber supply means 20 moves in the roll axial direction J, such that the continuous rubber material M1 to be put on the supply conveyor 18 has a meandering shape of a width corresponding to a width of a rubber sheet; and a partial width moving mode in which the rubber supply means 20 moves in the roll axial direction J, such that the continuous rubber material M1 to be put on the supply conveyor 18 has a meandering shape of a width obtained by excluding widths of both edge portions of the rubber sheet from the width of the rubber sheet.SELECTED DRAWING: Figure 2
