DEVICE FOR MANUFACTURE OF FLOOR COVERINGS FROM ROLL THERMOPLASTIC MATERIALS Russian patent published in 1997 - IPC

FIELD: welding of long-length polymeric articles. SUBSTANCE: material alignment mechanism is arranged between unwinding and edge shearing mechanisms and is made in form of heated table for resting the material. Ready product collecting mechanism is located at side from welding mechanism. Heated table for resting the material is made in form of thermal pan with support framework and coil for heat carrier. Edge shearing mechanism is made in form of measuring plate located along processing path and furnished with disk shears for cross and longitudinal cutting of material. Welding mechanism is made in form of conveyor for transportation of material and two infra-red radiation sources installed in tandem over transported material. Ready product collecting mechanism is made in form of inclined plane located at level of welding mechanism conveyor and containerization device located under inclined plane. EFFECT: enlarged operating capabilities. 5 cl, 3 dwg
