Abstract
Abstract Winders capable of production of consumer rolls of an elongated web. A turret assembly has spindles rotatable about respective spindle axes and movable along a path through a series of index stations. A spindle drive is operable to produce spindle rotation at least at the start-up station and a turret drive is operable to move the spindles through the stations. A roll unloader is adjacent the roll unload station, a core loader is adjacent the core load station, and the loader and unloader each have elements movable parallel to the spindle axes to respectively slide fresh cores over and remove wound rolls from the spindles. A roll starting or tucking assembly comprises an enveloping member mounted adjacent the start-up station and movable across the path between a retracted position and an enveloping position adjacent a spindle at the start-up station, and a web tucking member mounted for movement about a tucking axis between a retracted position and a tucking position. The tucking member when in the tucking position extends between the enveloping member and the spindle at the start-up station, whereby the enveloping and tucking members cause the web to envelop the spindle from opposite sides thereof. Also shown are a core loader in the form of a tray and pushers; a core unloader in the form of grooved rings confined to the spindles and engaged by a stripping fork; simultaneous dependent drive of the loader and unloader; a hopper having a wall moving to and fro through a special path; a triggered idler method of controlling belt drive of the spindles and other important features. In another aspect spindle start-up for webs having perforations is accomplished by a blunt-edged blade which by impact breaks the perforations, with the free end carried about the blade edge into tucked relation. For nonperforated webs there is a severing member downstream from the tucking blade.
