Abstract: A laminate placed on a supporting belt is covered with an air-impermeable sheet, then compressed by sucking air from sucking mechanisms, and the laminate is cut by a cutter which is supported at two locations. A belt retaining mechanism comprises a number of belt support plates for supporting a belt, support posts extending downwardly therefrom, and receiving plates supported by a receiving plate retaining mechanism disposed on longitudinal beams. A travel body and cam plates are operatively connected, and the support posts are supported on the receiving plates at a location other than a cam groove of each cam plate to stabilize the belt support plates. The receiving plates are separated within a movable recess of the belt, so that the support plates are raised by the cam groove.
Abstract: A laminate 88 placed on a supporting belt 3 is covered with an air-impermeable sheet 89. Air is withdrawn from suction ports 37 and 44 formed in upper surfaces of a number of belt support plates 9 constituting a first suction mechanism 34 and an upper surface of a second suction mechanism 35 disposed proximate to front and rear sides of a movable recess 6 formed in the supporting belt 3 through vent holes 3a formed in the supporting belt 3, respectively. The laminate 88 is supported on the supporting belt 3, and cut by a cutter 26 which is supported at upper and lower parts thereof.
