摘要

The subject of the present invention is a device for cutting and attaching the leading end of a web of a new roll onto a core of a winder. Device, essentially consisting of a cutting means (3) interacting with a means (4) for gripping the web and of a means (5) for attaching an adhesive strip or the like to the cut end of the web and for pressing and attaching the latter and the adhesive strip onto the core (1) of the new roll, characterised in that the cutting means (3) has the form of a caisson (box) (7) for accommodating and guiding a cutter (8) which can be displaced in a slot (8'), the said caisson being mounted on the chassis (9) for guiding the web, arranged with the possibility of tilting, under the action of a jack (ram) (10), in the chassis (11) of the winder (2), the said caisson (7) being displaceable transversely to the direction of advance of the web, its face bearing the slot (8') being turned towards the said web. The invention is more particularly applicable to winding up fragile materials. IMAGE
