Title: Surfacing foam with e.g. scourer layer - by coating moving substrate with fused resin powder from heated roller and bonding prod. to web of surfacing material with pressure roller
Inventor: SICKINGER ERICH
IPC: B29C63/02
Filed: 1992-12-01
Abstract: A surfacing device utilises a fusible resin powder on the back of a foam substrate of 5-80 kg/m3 polyether, polyester, "Pantex" or a viscose resin/mat slab material etc. The coating bonds a harder material e.g. a scouring mat, a massaging surface, cleaning surface, etc. onto it. The fusible powder is fed from a hopper onto a revolving heated roller and the substrate is passed to that roller on a conveyor belt. A melted film is rolled onto the substrate and the harder skin material is bonded onto it by a second roller. Resin powder (6) is deposited from the hopper (1) onto the roller (2) below, using e.g. a screw feed or a vibrator. The roller (2) is driven and (e.g.) doctored. It is heated e.g. by a silicone oil agent or by a radiation heater, so that the deposited resin powder (6) forms a liquid film (7) which is applied to the substrate (8) passing underneath. The speed of rotation of the roller (2) is selected to produce a resin film of the desired thickness (7). The substrate (8) lies on the belt (4). An infra-red heater (5) can further fuse the resin coating before the material plus an added skin (9) (e.g. scouring mat) are bonded together by the next roller (3). The product (10) is finally cut to size as required. ADVANTAGE - The arrangement can cheaply surface sheets or webs of any width.
