Title:
TRAVELLING AND FORMING APPARATUS
Document Type and Number:
Japanese Patent JPS5736028
Kind Code:
A
Abstract:

PURPOSE: To form accurately and without the buckling of the material with a simple construction, by forming while feeding the chuck sending-out cylinder with fasfer speed than that of the feeding of the material.

CONSTITUTION: When the tip of the material W reaches a detecting device 8, of which signal actuates the solenoid of a cylinder 6 to move the cylinder 6. The advancing speed V1 of the cylinder 6 is preadjusted faster than the feeding speed V0 of the material. According to the advancing of the cylinder 6, a chucking device 3 engaging with the cylinder 6 holds the material W, and the speed becomes V0 while making the material W in stretched condition. The forming apparatus 5 cut the material W while advancing due to the pushing from the chucking device 3 to actuate the cylinder 4. When the forming apparatus 5 moves to the positional signal output device 7, the output signal changes the solenoid of the cylinder 6, and the chucking device 3 is retreated to restore its formal position.
