Abstract

A score knife positioner includes a carriage bracket having a locating tab for receiving a score knife assembly. Linear bearings are attached to the carriage bracket and are configured to engage with a pair of guide rails. The linear bearings are each staggered with respect to linear bearings of adjacent carriage brackets and located so that score knife positioners on either side of a particular score knife positioner can be nested together. The carriage bracket has a width less than a width of the score knife assembly and allows adjacent score knife assemblies to be positioned so that there is less than one-half inch between score knifes. Score knife positioners can be moved to a desired location and locked into place via a carriage brake attached to the carriage bracket.

Abstract

A web is wound onto an in-line core instead of a separate core. At the start of the winding process, a core-forming substrate attached to the leading edge of the web is wound into an in-line core. The web is wound around the in-line core. For streaming operation, a composite substrate-web stream comprising an alternating sequence of attached core-forming substrate segments and web segments is produced. The first core-forming substrate segment is wound into a first in-line core, and the first web segment is wound around the first in-line core. The composite substrate-web stream is cut. The second core-forming substrate segment is wound into a second in-line core, and the second web segment is wound around the second in-line core. The composite substrate-web stream can be slit longitudinally to produce multiple composite substrate-web stream strips. Multiple composite substrate-web stream strips can be wound in parallel on a single mandrel.

Abstract

In a winding assembly (630) for winding web rolls (830), an enveloper assembly is used to initiate winding of a web stream onto a pre- formed core (820) or to initiate winding of a core- forming substrate into an in-line core. The enveloper assembly comprises a first support arm (870) operatively coupled to a second support arm (872); a third support arm (874) operatively coupled to the second support arm; and an enveloper roller (846) operatively coupled to the third support arm. The enveloper roller is movable along a cylindrical surface from a first position (889 ) to a second position. The enveloper assembly accommodates a wide range of core diameters. For winding non-adhesive web streams, a tail tucker can be used in conjunction with the enveloper assembly to initiate winding. In conjunction with apparatus for inserting core-forming substrates or adhesive tabs onto a web, the winding assembly can perform high-volume, streaming production of wound web rolls.

Abstract

A system for slitting a web includes a carriage assembly having an elongate housing including a first wall, where the first wall defining a longitudinal axis. A first plurality of rails can be mounted on the first wall, wherein the plurality of rails extends parallel to the longitudinal axis. At least one of the plurality of rails can have a substantially circular cross section, among others. The system also includes a first plurality of carriers. Each carrier can be adapted and configured to support an instrumentality such as a blade for performing an operation (e.g., cutting) on a web of material. The carrier body includes a first body portion and a second body portion. Each of body portion includes at least one mounting feature for mounting the carrier on a the plurality of rails.
