초록

A method and system for determining the lateral position of an edge of a web are disclosed. The system includes an array of light transmitting elements and a corresponding array of lenses and an array of light receiving elements and a corresponding array of lenses. The light transmitting elements are each paired with a light receiving element and the light transmitting elements each transmit a beam of light energy towards the corresponding receiving element. The beams of light can be occluded by a web passing between the transmitting elements and the rec...

청구항

The invention claimed is: 1. A system for use in detecting an edge of a web of material, the system comprising; a plurality of light sources being operative to transmit light, the plurality of light sources being arranged in two substantially parallel rows that are offset from one another so as to form a staggered pattern; a first plurality of lenses positioned such that each of the first plurality of lenses focuses light transmitted from one of the plurality of light sources; a second plurality of lenses positioned such that each of the second pluralit...
