Abstract
Abstract Apparatus for winding a continuous web into a plurality of spools. The web partially wrapping a power driven winding drum is in a nipping relationship between the winding drum and the winding web spool. A core in synchronous speed is brought into light engagement with the web and winding drum. The core is then indexed to the position where the new spool will be started. Simultaneously, a driven enveloper roll is brought into engagement with spool to keep it winding while being moved away from the winding drum. Partially wrapping the core and enveloper roll the web is ready to be severed by a power actuated knife and transferred to the core. The knife is located transversely across the moving web between the core and enveloper roll. Severing the web near the core the knife urges the leading end of the severed web to wrap the core and be carried into the nip between the core and winding drum. Without stopping or slowing down the web and without adhesives on the core, a new spool is started winding. The knife may be provided with a means, such as a brush or sponge to assist in wrapping the web against the core.
