PURPOSE:To obtain a small-size and cheap bonder of a simple structure by combining a tip rectifying part, a tip supplying mechanism, a bonding mechanism, a rear end rectifying part, and a rear end supplying mechanism in such a way as to permit a specific action. CONSTITUTION:A slide base 44 is retracted, a support plate 43 is pulled out of a sheet material S, the piston rod 12 of an air cylinder 11 is projected, and the rear end of the sheet material S is supplied to a molding drum 1. At the same time, a movable base 6 and a rectifying part 18 are moved, and the position of the rear end of the sheet material S is retracted by as much as thickness of the rectifying projection from the position of the tip face Sa at the starting time of bonding. The piston rod of the cylinder 40 is projected, a pressing claw 38 is turned, and the rear end of the sheet material s rectified in a straight line from is pressed on and bonded to the molding drum 1. Since the tip and rear ends Sa and Sb of the sheet material S are rectified in parallel and in a straight line form, both the ends Sa and Sb are easily and exactly butted against and bonded with each other. At this time, an electromagnet 26 is demagnetized. |
