Abstract
Web preparation apparatus for use on splicers of the type employing a web positioning bar supporting the leading end of the ready web includes a series of teeth spaced along the length of the preparation bar at one face thereof and a pressing and cutting tool which cooperates with the positioning bar and projections so that when the leading end segment of a ready web is draped over the positioning bar and the tool is engaged to the bar and manipulated in association with the bar, the tool presses a web segment against the face of the bar so as to impale that segment on the teeth thereby removably securing that segment to the bar while simultaneously trimming the web along a line downstream from the impaled web segment.
Claims15
In a splicer of the type having a splicing station, a web preparation station and a web positioning bar movable between the two stations, web preparation apparatus comprising
- A. a series of projections spaced alone the length of the positioning bar at one face thereof, and
- B. a tool engageable against the positioning bar after the leading end segment of a ready web is draped over the bar, said tool having means for pressing the draped web segment against said face of the bar so that said web segment becomes impaled on said projections thereby removably securing said web segment to said bar.
In a splicer of the type having a splicing station and an elongated web positioning means located at the splicing station, web preparation apparatus comprising
- A. a series of projections spaced along the length of the positioning means, and
- B. a tool engageable against the positioning means after the leading end segment of the ready web is located at the positioning means, said tool having means for pressing the web segment against said positioning means so that said web segment becomes impaled on said projections, thereby removably securing said web segment to said positioning means.
Web preparation apparatus for use in a splicer having a splicing station and elongated web positioning means located at the splicing station which positioning means has a series of projections, said apparatus comprising
- A. a bracket,
- B. retaining means secured to the bracket,
- C. a roller having a circumferential groove,
- D. a circular knife blade mounted coaxially to the roller, and
- E. means for rotatively securing the roller and knife blade bracket so that the peripheries of the roller and blade are spaced from the retaining means a distance whereby, when the bracket is placed against the positioning means with the roller, and blade and the retaining means engaging opposite surfaces of the positioning means and the bracket is drawn lengthwise along the positioning means, said roller presses a web end segment located at the positioning means onto said projections, said projections being received in the groove in said roller, while said knife blade trims off the leading edge of said web.
