Winder roll starting apparatus for thick webs

摘要

A winder has a scraper mounted about the axis of a winder drum for circumferential movement. The scraper has a semi-cylindrical concave surface which extends in the cross machine direction, the concave surface meets a second surface to form a scraping edge. The scraping edge engages the winder drum, scraping a web from the surface of the winder drum and pressing the web into engagement with double-sided sticky tape on a winder core with the concave surface. An alternative embodiment scraper has a flexible blade which extends in the cross machine direction and which functions similar to a spatula to scrape the pulp web off the surface of the winder drum and wipe the pulp web onto the double-sided sticky tape on the winding core.
