Title: Circular knitting machine - has enclosed lubrication system
Inventor: ARNOLD ROLF
IPC: D04B35/28
Filed: 1990-12-05
Abstract: A lubrication system for a circular mesh formation assembler in which the mechanical elements surround a central tube. The tube stands on a base welded into an oil tank. The tank pref. contains a sump of oil which is sealed in by welding a short tube into the base. The longer tube stands on this. to pass the meshed article down the centre with oil surrounding the outside. The oil is pumped internally to the working elements which are mounted on the outside of the tube, lubricating mesh assembly elements or circular knitting elements. The tank is sealed at the top by a lid sealed by welding to the tube but left open at the edges. This gives ease of access for repairs to the working elements. ADVANTAGE - The oil is sealed into the tank and working elements. (3pp Dwg.No.0/1)
