Adhering device for bandlike material

Abstract

Abstract PURPOSE:To enable both ends of a bandlike material to be connected uniformly by a method in which the bandlike material is cut, and when the residual part is adhered, the final end of said material is pinched over its total width by the pinching means, and then moreover the peripheral speed of a forming drum and the moving speed of the pinching means are controlled so as to provide a constant ratio. CONSTITUTION:The initial end 9a of a bandlike material 9 is held by pinching over the total width by pinching means 88, 89 until immediately before the adhesion. Simultaneously with cutting, by the operation of a motor, the final end 9b of the residual bandlike material 9 is adhered to the periphery of a forming drum 1, while said final end is pinched by the pinching means 88, 89. The moving speed of the pinching means 88, 89 and the peripheral speed of the forming drum 1 are controlled so as to provide a constant ratio at any continuous points, and the adhesion is carried out, whereby the initial end and the final end of the bandlike material 9 are caused to exactly coincide with each other. When a pinching part 106 is brought into contact with the top part of the forming drum 1, the rotation of the forming drum 1 and the movement of the pinching means 88, 89 are stopped. The initial end 9a of the bandlike material is connected uniformly and firmly to the final end 9b thereof.
