A mandrel cupping assembly for releasably engaging unsupported ends of a plurality of mandrels is disclosed. The mandrel cupping assembly comprises a cupping arm turret having a cupping arm turret central axis, a mandrel cup cooperatively associated with each mandrel of the plurality of mandrels, and a first actuator.

Mandrel cupping assembly

A web rewinding apparatus having a mandrel cupping assembly for releaseably engaging unsupported ends of a plurality of mandrels is disclosed. Each of the plurality of mandrels extends generally parallel to the web winding turret assembly axis. Each of the mandrels is driven in a closed mandrel path about the web winding turret assembly axis. The mandrel cupping assembly comprises a cupping arm turret having a cupping arm turret central axis, a mandrel cup cooperatively associated with each mandrel of the plurality of mandrels, at least three motion limiting devices disposed upon the cupping arms, and a first actuator.

A winder for winding continuous webs or interleaved web segments into rolls is disclosed. The winder has first and second rollers, a pressure assist device, a winding spindle, and a continuous belt having first and second surfaces. The belt is disposed about the first and second rollers. The web material is disposed upon at least a portion of the first surface of the belt. The winding spindle receives the web material when the spindle is proximate to the web material disposed upon the first surface of the belt. At least one of the longitudinal axis of the first roller and the longitudinal axis of the second roller is adjustable relative to the winding spindle. The pressure assist device is disposed proximate to the second surface of the belt and is adjustable relative to at least one of the second surface of the belt and the winding spindle.

Hybrid winder

A method for rewinding a web material is disclosed. The method comprises the steps of: a) providing a conveyor belt having opposed first and second surfaces; b) providing a pressure assist device proximate to the second surface of the conveyor belt; c) disposing the web material on the first surface of the conveyor belt; d) providing at least one winding spindle having a speed profile proximate to the web material disposed upon the first surface of the conveyor belt; e) adjusting a position of at least one of the conveyor belt and the pressure assist device relative to the winding spindle to provide a compressive force to the surface of the winding spindle by the conveyor belt; f) adjusting a speed of the at least one winding spindle according to the speed profile; and, g) transferring the web material to the at least one winding spindle from the conveyor belt.

Process for winding a web material

A web winding apparatus and a method of operating the apparatus are disclosed. The apparatus can include a turret assembly, a core loading apparatus, and a core stripping apparatus. The turret assembly supports rotatably driven mandrels for engaging hollow cores upon which a paper web is wound. Each mandrel is driven in a closed mandrel path, which can be non-circular. The core loading apparatus conveys cores onto the mandrels during movement of the mandrels along the core loading segment of the closed mandrel path, and the core stripping apparatus removes each web wound core from its respective mandrel during movement of the mandrel along the core stripping segment of the closed mandrel path. The turret assembly can be rotated continuously, and the sheet count per wound log can be changed as the turret assembly is rotating. The apparatus can also include a mandrel having a deformable core engaging member.
