Abstract
An apparatus for automatically cleaning the clips on a web processing apparatus is described. The apparatus includes a scraper for scraping the web supporting surface of the clips on the web transporting machine, and also desirably includes a clip opener, for facilitating opening of the clip to enable the scraper to easily access the clip web support surface. The scraper is desirably supported in a manner that enables it to move upwards and downwards relative to the web supporting surface of the clips, to account for variations in clip height and positioning. The clip cleaner can be readily applied to existing web processing apparatus, such as tenter frames, and desirably can be selectively moved from an operative position to an inoperative position.
Claims19
An apparatus for cleaning the clips on a web processing device comprising:
- a scraper having a substantially planar edge and means for supporting said scraper proximate the clips of a web processing apparatus, whereby said scraper contacts a web supporting surface of the clips as the clips travel past the scraper when the web processing apparatus is in operation.
A web processing apparatus comprising:
- a plurality of clips adapted to hold the sides of a web and travel along an endless pathway including a first web holding pathway section and a second return pathway section, and a clip cleaner comprising a scraper having a substantially planar edge, said scraper being operatively associated with said apparatus such that said substantially planar edge contacts said clips as they travel along said endless pathway to thereby scrape and remove debris therefrom.
A method of cleaning the clips of a web processing apparatus having a plurality of hinged clips that travel along an endless pathway to carry a web through at least one processing station, said method comprising the step of:
- securing to the web processing apparatus a scraper having a substantially planar edge such that said scraper contacts a web supporting portion of said clips as they travel along their endless pathway, to thereby scrape and remove debris therefrom.
