Abstract

A device for the inspection and repair of a roll of web material includes an unwind mandrel, a rewind mandrel, an inspection area and a splice area. A flaw in the web is detected at the inspection area, whereupon the web is braked to a halt.
Where the splice area is adjacent to or coincident with the inspection area, the flawed portion of the web can pass well beyond the splice area before the web comes to a halt. Provided herein is a web-indexer device that includes a reciprocating indexer shuttle having idler rolls mounted thereon, with further idler rolls mounted to the machine such that the web material can be strung between them in a substantiallyboustrophedonic configuration. Control means are provided to allow the operatorwho has caused the web to be braked to a halt upon detecting a flaw, to move theindexer frame so as to retrieve a portion of the web so as to bring the flaw back to the splicing station for repair, without having to reverse the rotational direction of the unwind mandrel or the rewind mandrel.
