ABSTRACT:
A surface winder and roll changing mechanism includes primary arms rotatable through 360.degree. between a substantially horizontal initial position where a new core can be loaded, a second position where the primary arms transfer the new core with the roll being formed thereon to secondary arms, and an intermediate position between the initial and second positions in which the web is cut and started on the new core, the primary arms being rotatable in one direction to return them to the initial position. In one embodiment, a grab knife is carried by the primary arms, and the web cutting knife is separately mounted on the frame, while in a second embodiment, both the grab knife and the cutting knife are carried by the primary arms. A single cutting knife or a reciprocating double cutting knife assembly may be used in either embodiment.
