Abstract

PURPOSE:To enable to perform safety winding-in of a coat material without producing any wrinkle at the forward end of the coat material, by a method wherein a work to wind in the forward end of the coat material is automatically performed. CONSTITUTION:The forward end of a coat material W fed through a molding process is fed out by a given distance by means of pinch rolls 10, 11a, and 11b. The forward end of the coat material W is swung by a given angle alpha1 to a position, allowing the forward end to be fed over a cell 27 of a wind roll, with the aid of a guide device 1. The coat material W is wound around the wind roll 2a in a state in that a slack X is left and is positioned between a liner W1 and the cell 27. From this state, the roll 2a is rotated in the direction of an arrow mark, and after the coat material is continuously wound by a given length through utilization of a friction force produced between the liner W1 and the cell 27, the material is cut. This, since the coat material W and the liner W1 are stretched by means of the pinch rolls 11a and 11b during cutting, enables safety winding-in of the material without production of wrinkle at the forward end.
