Abstract

DC60 (15/12/43) This invention involves a method and equipment for making a spiral tube. The hollow thermoplastic periphery (1) has a significant rectangular cross-section, which This method consists of steps of The thermoplastic outer contour curl (1) around the barrel (2) and the confluence of the adjacent rings by welding and smoothing the outer seam (13) by means of Extra heat and body for smoothing against weld joints (13) This invention has a special effect and that the outer contour of the thermoplastic (1) when fed to the barrel (2) ) Comes down on the first stationary part (3), consisting of a way of spaced shifting (5) provided throughout the figure around which the welding is performed. After which the molded inner weld joint (11) is provided, it runs through the circular groove (14), running around the first stationary part (3) where the weld joint The inside (11), as well as the outer weld seam (13), are done by using more heat. And the body for the smoothing, stationary (10), against that weld, and by this pipe, when both of the welded surfaces (11,13) were transmitted to the section (4) of the rotary ejector cylinder (4) causes the tube to circulate and create a coiling motion. Of thermoplastic periphery (1) Invention This involves a method and equipment for making a spiral tube. The periphery of a hollow thermoplastic (1) having a significant rectangular cross-section, in which the method consists of steps; The thermoplastic periphery curl (1) around the barrel (2) the confluence of the adjacent loops by welding and smoothing the outer seam (13) by means of a Extremely hot and the body for smoothing lean against the weld joint (13) This invention has the effect that the outer contour of the thermoplastic (1) when fed to the barrel (2) comes. On the first part that is stationary (3) It consists of an indeterminate sliding path (5) provided throughout, surrounding a figure where welding is an integral part. After the formed inner weld joint (11) is provided, it runs through the circular groove (14), running around the first stationary section (3) where the inner weld seam. (11) Likewise, outer weld seams (13) are performed by heat rather than normal. And the body for the smoothing, stationary (10), against that weld, and by this pipe, when both of the welded surfaces (11,13) were transmitted to the section Of the rotary driven cylinder (4) causes the tube to circulate and the coiling motion is generated. The perimeter of the thermoplastic (1):
