Apparatus for attaching belt-like materials

An apparatus for attaching belt-like materials, comprising rotating means for rotating a forming drum, holding means located apart from said forming drum for holding continuous belt-like materials along their entire widths to be supplied to the forming drum, embracing means located between said forming drum and the holding means for embracing the belt-like materials along their entire widths, reciprocating means for reciprocating said embracing mans between the holding means and the forming drum, cutting means for cutting the belt-like materials in their width directions along lines between said holding means and said embracing means which have been stopped in the proximity of said holding means, said belt-like materials being held by said holding means and said embracing means, and control means for controlling said rotating means and said reciprocating means so that circumferential speeds of the forming drum and moving speeds of the embracing means are at a constant ratio, thereby after holding one portions of the belt-like materials attached to said forming drum with predetermined amounts along their entire widths by means of said holding means and embracing means, cutting said belt-like materials between said holding means and embracing means by means of said cutting means, and rotating said forming drum, while moving said embracing means embracing trailing ends of the belt-like materials toward said forming drum in controlling said circumferential speeds of said forming drum and said moving speeds of said embracing means at a constant ratio to attach remaining portions of the cut belt-like materials to said forming drum under an appropriate tensile force.
