Manufacturing device of sheet-like belt

Abstract

A manufacturing device includes a belt table situated adjacent to a master roll table; a hand feeding the master roll from the master roll table to the belt table; and a cutting device cutting the master roll between the master roll table and the belt table, wherein the hand includes a first hand which keeps holding a front part of the master roll in a feeding direction of the master roll from start to end of feeding of the master roll and a second hand which holds a rear part trailing the front part in the feeding direction

What is claimed is: 
     
         1 . A manufacturing device of a sheet-like belt manufacturing a sheet-like belt by cutting a master roll formed by covering multiple belt cords lined up parallel to one another with rubber, comprising:
 a master roll table on which the master roll is placed;   a belt table situated adjacent to the master roll table;   a hand feeding the master roll from the master roll table to the belt table; and   a cutting device cutting the master roll between the master roll table and the belt table,   wherein the hand includes a first hand which keeps holding a front part of the master roll in a feeding direction of the master roll from start to end of feeding of the master roll and a second hand which holds a rear part trailing the front part in the feeding direction.   
     
     
         2 . The manufacturing device of a sheet-like belt according to  claim 1 , wherein:
 the first hand is a hand which repeats feeding of the master roll for a short distance and stopping of the feeding from start to end of the feeding of the master roll; and   the second hand is a hand which holds and feeds the master roll while the master roll is fed for a short distance, and releases the master roll, moves backward in the feeding direction of the master roll, and holds the master roll again while the feeding of the master roll is stopped.   
     
     
         3 . The manufacturing device of a sheet-like belt according to  claim 1 , wherein:
 the first hand and the second hand are hands which hold the master roll by forcing the master roll to float above the master roll table and the belt table by attraction.   
     
     
         4 . The manufacturing device of a sheet-like belt according to  claim 3 , wherein:
 the master roll table is provided with a blow hole from which air blows upward, and air blows out from the blow hole toward the master roll placed above while the master roll is fed.   
     
     
         5 . The manufacturing device of a sheet-like belt according to  claim 1 , further comprising:
 a slip detector detecting a slip of the master roll on the first hand or the second hand.
