Scraping treatment for leather hides - eliminates unpleasant manual labour and improves utilisation of scraping machine

摘要

The scraping treatment involves bringing a hide from a supply station, inserting about half the length of the hide between the open tools of a scraping machine, closing the tools and drawing out the hide which scrapes the first half. The hide is then reversed and the untreated half inserted into the scraping machine for treatment. The half-treated hide is now returned to a waiting station upstream of the scrapping machine and pref. alongside the supply station. The scraping machine is then fed alternately with a fresh hide from the supply station and a reversed, half-treated hide from the waiting station. Hides sent forward from both the supply and waiting stations to the scraping machine are pref. suspended by hook attachment of trolley of an overhead runway conveyor. The runway is pref. a closed circuit track so that a trolley can move around from the rear of the scraping machine back to the supply station.
