Abstract
An apparatus for attaching belt-like materials has a rotating unit for rotating a forming drum, a holding unit located apart from the forming drum for holding continuous belt-like materials along entire widths to be supplied to the forming drum, embracing units located between the forming drum and the holding units for embracing the belt-like materials along entire widths. A reciprocating unit is used for reciprocating the embracing units between the holding unit and the forming drum. A cutting unit is used for cutting in width directions the belt-like materials held by the holding unit and the embracing units. The apparatus includes control unit for controlling the rotating unit and the reciprocating unit so that circumferential speeds of the forming drum and moving speeds of the embracing means are at a constant ratio.
