Abstract: A machine for fusing plastic plates includes a frame and a movable table mounted to the front end of the frame and movable along a longitudinal direction of the frame. Two spaced screw driving devices are secured to the underside of the movable table. Two screw rods are provided and each has a first end fixed to the frame and a second threaded end coupled to an associated screw driving device. The screw driving devices are driven to urge the movable table to move along the longitudinal direction of the frame. A rear compressing device is mounted behind the movable table for clamping a first plastic plate. A front compressing plate that is movable in a vertical direction is provided so as to cooperate with the movable table for clamping a second plastic plate. A fusion blade is provided for fusing a front end face of the second plastic plate with a rear end face of the first plastic plate. The front compressing plate further includes a fixed seat mounted thereon.

Abstract: A machine includes a frame having a first vertical track, a second vertical track, and a horizontal guiding device. A lower press plate is movably guided by the first vertical track. An upper press plate is movably guided by the second vertical track. The upper press plate and the lower press plate may tightly hold two plastic foam slabs therebetween. A heating blade is heated and passed through an interface between the two plastic foam slabs to join the plastic foam slabs together.
