ABSTRACT:
An apparatus for applying an adhesive coated tape on a core mounted on a mandrel, includes a mounting frame having mounted thereon an adhesive tape supply roller, a rewind roller, an idler roller mounted between the supply and rewind rollers such that the adhesive tape on the idler roller can be sandwiched between the idler roller and mandrel and transferred to the mandrel with the carrier layer being wound on the rewind roller, a motor for rotating the rewind roller, and a knife assembly pivotally mounted thereon adjacent the idler roller for cutting the adhesive layer extending between the supply roller and mandrel after the adhesive layer has been transferred to the mandrel; two link arms pivotally connecting the mounting frame about a pivot shaft secured to a main frame; a piston-cylinder assembly for pivotally moving the mounting frame about the link arms and relative to the mandrel such that the adhesive tape around the idler roller can be transferred to the mandrel; and a cam plate for pivotally moving the knife assembly to cause the adhesive layer which sticks to the knife to disengage from the knife assembly and fall onto the carrier layer.
