ABSTRACT:
Web-splicing apparatus comprises a web splicer and, associated therewith, an air mover and web-presentation means operable to present to the inlet end of the air mover the leading end of a first web extending from a reel and the leading end of a second web extending from another reel, which air mover is operable to feed the leading end of said first web from said presentation means to and through a splicing zone, to serve as a guide for subsequent continuous passage of that web and further operable to feed the leading end of the second said web from said presentation means to said splicing zone during continuous passage of the first web through the air mover. Web-severing means may be disposed for operation in the splicing zone and web-withdrawal means, suitably further air-mover means, downstream of that zone. Splicing-patch supply means comprises a continuous backing strip carrying spaced adhesive patches, means for advancing the said strip past patch-detachment means, a movable vacuum-supplied holding element for receiving detached said patches, and a vacuum-supplied stationary element on the side of the web path remote from said movable element, a detached patch being pressable onto a web by movement of the first-named element towards the second-named element.
