The scraper 41 of the scraper unit 4 can be adjusted in position and angle according to different widths of the workpiece (cloth S). In addition, as shown in FIGS. 1 and 3, the scraper unit 4 may further include a rubber collecting box 42 for receiving the rubber scraped by the scraper 41. As shown in the figure, each scraper 41 is equipped with a rubber material collection box 42. The rubber material collected by the rubber material collection unit 42 can flow to other collection containers as desired via the rubber pipe or be reused as required.
