Embodiment Construction

[0031] The following terms used here have the following meanings:

[0032] The "machine direction", denoted MD, is the direction parallel to the direction of paper movement within the paper processing equipment.

[0033] The "cross machine direction", denoted CD, is the direction perpendicular to the machine direction.

[0034] A "nip" is a loading surface that connects the centers of two parallel axes.

[0035] A "core winding cycle" is the time required to complete the rewinding of a predetermined length of paper onto a single core to produce a consumer product roll.

[0036] A "log" is a roll of paper wound on a core that has completed a core winding cycle.

[0037] to attach figure 1 By way of example, it is a web rewind device 60 that rewinds a web 50 from a parent roll (not shown) onto a core layer 302 supported on a mandrel 300 of a rotary turret winder 100 . During web rewinding, web 50 travels in machine direction path 53 into perforation roll 54 which travels in ...

Abstract

A web transfer and chop-off assembly for a paper web rewinder used in a paper converting operation capable of maintaining positive control of the web (50) at all times. The web transfer and chop-off assembly delivers a web (50) to an empty core (302) faced with glue and supported on a mandrel of a web winding turret assembly (100), at about the same time the web is severed from a fully wound core (51) supported on a second mandrel on the turret assembly (100).A web transfer and chop-off assembly for a paper web rewinder used in a paper converting operation capable of maintaining positive control of the web (50) at all times.

Description

technical field [0001] The present invention relates to a web rewinder for unwinding a parent roll of web stock material, such as paper, and rewinding the web onto a core to make a consumer roll of web product, such as paper towels or Toilet paper rolls. More specifically, the present invention relates to a web cutting and transport mechanism providing improved reliability to the web rewinder. Background technique [0002] A rewinder is a device used to unwind a parent roll of web stock, such as paper, and rewind the web into a consumer product roll. Such consumer product rolls include paper towels as well as toilet paper, which typically consist of parallel tearable individual sheets. The rewinder may include perforated cylinders for producing transverse seam lines on the web at sheet-length intervals, these lines of weakening being provided to facilitate tearing. Rewinders often include a rotating turntable set supporting a number of mandrels which in turn support the c...
