Abstract: PURPOSE:To permit to eliminate temperature difference between both side members and keep them in the same temperature by a method wherein a heater, extending in the longitudinal direction of the mouthpiece, is provided near the outlet port of molten resin of a slit clearance in a member provided with a regulating means. CONSTITUTION:The plate-like heater 39, extending along the whole length of the lip member 33 in the longitudinal direction thereof, is attached to a part near the outlet port of molten resin of slit clearance 35 of the lip member 33 provided with the regulating means 38, or the lower surface side of the lip member 33. A drip plate 41, for preventing dropping of resin through the part of the regulating bolt 38, it attached to the lower surface side of the heater 39 through an insulating member 40. Temperature difference between the lip member 32 and the lip member 33 is eliminated by setting the voltage of the heater 39 properly. On the other hand, the heater 39 is extended in the longitudinal direction of the mouthpiece 30, therefore, the lip member 33 may be heated uniformly in the longitudinal direction of the cap 30.

Abstract: PURPOSE:To clean a roll automatically with high efficiency by providing a cleaning head for removing dust adhered onto the surface of sheet carrying roll movably in longitudinal direction of roll while contactably/separatably against the roll. CONSTITUTION:When cleaning a sheet carrying roll 2, a motor 10 is first driven to travel a truck 5 along a rail 9 thus to move to the lower position of specific roll 2. Then a motor 14 is driven to move the rail 9 through a chain 13 in longitudinal direction Y of roll 2. Consequently, a cleaning head 3 mounted on the truck 5 is moved from the retreated position A to specific position B where the roll 2 is contaminated. Thereafter, the cylinder 7 is lifted to contact the cleaning head 3 against the lower face of roll 2 and to rub against the surface of roll 2 through rotation of roll 2 thus to clean off dust adhered onto the surface of roll.
