摘要： PROBLEM TO BE SOLVED: To obtain a resin sheet having beautiful appearance on both surfaces thereof. SOLUTION: The resin sheet 33 is extruded from an outlet 22 of a T-die, and one surface thereof is cooled by a first cooling roll 23 while the other surface thereof is immediately cooled by a second cooling roll 24. By parallelly providing the first and the second cooling rolls 23 and 24 as shown by Fig 1, the cooling interval between both surfaces of the resin sheet 33 is formed shorter than before and the gloss difference between both surfaces of the resin sheet is eliminated.

摘要： PROBLEM TO BE SOLVED: To certainly prevent the generation of excess or shortage of storage while achieving the miniaturization of an apparatus or molding line by minimizing the storage capacity of an accumulator part. SOLUTION: The accumulator part is provided to the molding line for using the strip continuously extruded from an extruder to mold the same into a product by a molding drum. When a molding time for molding the product by moving the molding drum is set to Tw, the standard extrusion speed during the molding time Tw of the strip from the extruder is set to Vw, the standard extrusion speed during a stop time is set to Vr and the standard supply speed of the strip to the molding drum is set to VO, formula (1): VO=(Vw×Tw+Vr+ Tr)/Tw is formed. The residual amount J in the accumulator part is measured, at each time when one molding of the product is completed, to obtain the difference F (=S-J) with standard storage quantity S and, during the stop time Tr, the molding drum is operated at the adjusted extrusion speed Vnr calculated by formula (2): Vnr=F/Tr.

摘要： PROBLEM TO BE SOLVED: To provide a sheet treating system having an integral accumulator to be compactly adopted in a structure of the system. SOLUTION: The sheet treating system continuously manufactures plastic sheets to be continuously supplied to an intermittently winding system by utilizing a sheet forming unit, a conveyor, the accumulator and a winder. In this case, the sheet is supplied to the accumulator disposed integrally with the conveyor along the conveyor. The accumulator is controlled in a circulating operation for providing a storage of continuously supplying sheet materials to enable the intermittent operation of the winder. Edge trimming of the sheet is continued to the operation of the accumulator.

摘要： PROBLEM TO BE SOLVED: To stably convey for a long distance even in the case of an intermittently rotatable operation or the like without generating a deformation or an elongation at a rubber strip, by holding a lengthy rubber strip made of an unvulcanized rubber on one surface of a non-stretchable endless tape guided by a guide roller, and conveying the strip. SOLUTION: A non-stretchable endless tape 4 guided circumferentially by a guide roller is provided. A rubber strip P is held on one surface S1 of the tape 4, and conveyed from a rubber extruder 3 to a former. The tape 4 is folded to provide a stored accumulator 10, and the tape 4 is wound in a zigzag state between upper and lower guide rollers R1U and R1L at its forward accumulator 10A. The tape 4 is similarly wound between upper and lower guide rollers R2U and R2L even at the return accumulator 10B. Thus, a speed difference between circumferential speeds of the former and that of the extruder 3 is absorbed.
