Abstract
A web storage and handling system employing two concentric rings of rollers. The web is wound around the outer of the concentric arrangement and therefrom wound around the inner of the concentric arrangement. From the inner of the concentric arrangement the web passes over two canted idlers to be removed from the plane of the concentric rings to permit viewing and final storage.
Claims16
Web handling apparatus for use with first and second web storage means, comprising:
- a first plurality of rotatable members mounted proximate a first plane and arranged around a first axis, each rotatable member of the first plurality being rotatable about axes substantially perpendicular to the first plane;
- a second plurality of rotatable members mounted proximate the first plane and arranged around the first axis and surrounding the first plurality, each rotatable member of the second plurality being rotatable about axes substantially perpendicular to the first plane;
- canted means rotatable about an axis at an acute angle with the first plane, the web being wound around the first and second pluralities of rotatable members and the canted means between the first and second web storage means, the windings of web around the first and second pluralities being substantially parallel to the first plane, a predetermined one of the rotatable members of the first plurality operating to direct the web between the first and second pluralities and a predetermined one of the rotatable members of the second plurality operating to direct the web between the second plurality and the canted means so that the web is directed out of parallelity with the first plane between the second plurality and the second storage means;
- and
- control means operable to rotate the second plurality of rotatable members as a group around the first axis.

Web storage and handling apparatus comprising:
- rotatable means mounted for rotation about a first axis;
- a first plurality of rotatable members mounted on the rotatable means to rotate on axes substantially perpendicular to a first plane and spaced about the first axis;
- stationary means;
- a second plurality of rotatable members mounted on the stationary means to rotate on axes substantially perpendicular to the first plane and spaced about the first axis, the first and second plurality of rotatable members lying generally in a first plane;
- web supply means for moving a web along a path around the first and second plurality of rotatable members, one of the rotatable members operable to transfer the web between the first and second plurality of rotatable members;
- and
- canted means mounted for rotation about an axis at an acute angle to the first plane, the canted means receiving the web from one of the second plurality of members to transfer the web between the first plane and a second plane.
