Abstract

DC60 (04/07/54) The first (20) edge sewing unit and second (30) edge stitching printing unit are installed in a single extrusion machine. The first (20) edge stitching unit (20) is partially bending the edge (95) of the workpiece (93; 96), the part (93; 96) which has been partially bended. The second edge stitching (30) printing unit to the second edge stitching unit (30) will bend the edge of the workpiece (93; 96) as memory pending in. Here, bending the remainder of the edge (95) of the workpiece (93; 96) can be obtained. Can be completed with only one compression machine By moving downwards of Top-of-the-line (24,34) of the first-edge-sewing and the-first-edge-printing units. Sew the second edge (20,30) only, neither the cam nor the cam drive will be used. The first (20) edge sewing unit and the second (30) edge sewing unit are installed in a single extrusion machine. The first edge stitching unit (20) is partially bending the edge (95) of the workpiece (93; 96), the part (93; 96) where the bending is thin. Then part The print unit for second edge stitching (30) will perform the bending of the workpiece (93; 96) as necessary. Here, bending the rest of the edge (95) of the workpiece (93; 96) can be done completely. Can be achieved with a single extrusion machine By moving downward of the top form (24,34) of the first edge sewing unit and second edge sewing unit (20,30) only, no cam or cam drive is used. Somehow

Claims (4)

1.How to bend the edge It consists of the following steps: installation of the first (20) edge sewing and the second (30) edge stitching printing unit into a single extrusion machine. In order to make the first (20) edge stitching unit work on only partially bending the edge (95) of the workpiece (93; 96), this conveys the workpiece (93; 96), which There has been a partial perm. To move to Second (30) edge sewing unit and which in order to make the second (30) edge sewing unit work in the The remainder of the edge bending of the workpiece (93; 96), therefore, the preset bending of the edge (95) of the workpiece (93; 96) can be performed completely with the extrusion machine. Just one machine 2.Edge cutter Which will include The first (20) edge sewing unit for bending the edge (95) of the workpiece (93; 96) to half of the pre-determined full bending angle and the printing unit for edge stitching. The second (30) for bending the edge (95) of the workpiece (93; 96) in addition to half the corner. To the pre-determined full bending angle, such First (20) Edge Stitching Type Unit and such Second (30) Edge Stitching Print Unit are installed. In the same machine extrusion machinery 3. Edging tool, which is entitled under Clause 2, which also includes The first (40) transport part, which can be moved upward and downward via The top (22) of the first (20) edge sewing unit in order to place the workpiece (93; 96) on the first (20) edge sewing unit or so that The workpiece (93; 96) is fed to the first (20) stitching unit. The second workpiece (50) can be moved upwards and downwards through the Bottom form (32) of the aforementioned second (30) edge sewing unit for placement of the workpiece (93; 96) onto the print unit for such second (30) edge sewing or for protection. Send the workpiece (93; 96) to the second (30) edge stitching printing unit and the center workpiece conveyor (60), which is positioned between the first conveyor (40) as follows. And the aforementioned second (50) workpiece in order to support the above workpiece (93; 96) to be transported along the level from the first (40) workpiece to the Conveyor part The second (50) as above 4. Edge bending tools, which are entitled in accordance with claim 3, where each such first (40) conveying part, such second (50) workpiece conveyor and the center workpiece conveyor ( 60) It also includes rollers (61), which are arranged in order to protrude above the surface. Top of each section In such a way that the aforementioned workpiece (93; 96) can be conveyed in accordance with Levels can easily be placed on various (61) rollers through manual operation of the operator.
