TH30754B - Sealing unit for applying plastic foil to substrates. - Google Patents

Abstract

DC60 (08/06/54) This invention involves a sealing unit (8) for the application of plastic foil (7) to a flat substrate (1) by means of heat treatment and pressure by applying the sealing plate (11) to the active surface and the back plate (9), which will then be able to move relative to the plate, where the sealing unit (8) is bonded. with the die cutting unit (16), with the die cutter (15) and the opposite plate (21) for the subsequent cutting section (6) at the selected position in the flat substrate ( 1) In the area of the plastic film used In order to improve the sealing unit (8) according to the earlier Renaissance so that the cutting edge of The mold will no longer be the frayed fragments created by the backing or plastic, but will be clean and free of protrusions. According to this invention The sealing strip (11) of the sealing unit (8) has a convex area (14) and a concave area (13) on the active surface of the sealing plate facing. to the back plate (9) and the position of the concave area (13) in the sealing plate (11) will correspond to The position of the die cutter (15) so that the cutting section (6) is performed at the selected position in the Measured as the substrate (1), where due to the concave area (13) of the sealing strip (11), there is almost no Substrate heating (1) and laminating of the substrate This invention involves a sealing unit (8) for the application of plastic foil (7) to a flat substrate (1) by means of applying heat and pressure using a sealant. leak (11) to the active surface and back plate (9), which will then be able to move relative to the plate, where the sealing unit (8) is bonded to the template cutting unit (16 ) with die-cutting knife (15) and opposite plate (21) for cutting sections. (6) Subsequently at the selected position in the substrate, flat (1) in the area of the applied plastic film. in order to improve the sealing unit (8) according to the earlier Renaissance so that the edge of The mold will no longer be the frayed fragments created by the backing or plastic, but will be clean and free of protrusions. According to this invention The sealing strip (11) of the sealing unit (8) has a convex area (14) and a concave area (13) on the active surface of the sealing plate facing. to the back plate (9) and the position of the concave area (13) in the sealing plate (11) will correspond to The position of the die cutter (15) so that the cutting section (6) is performed at the selected position in the Measured as the substratum (1), where due to the concave area (13) of the sealing plate (11), there is almost no Substrate heating (1) and laminating of the substrate

Claims (9)

1. A sealing and cutting unit for applying plastic foil to a flat substrate material to form a laminate material by means of heat and pressure, comprising; a sealing unit, a die cutting unit and a drive for moving the laminate material from the sealing unit to the die cutting unit, said sealing unit comprising a sealing plate having a heated active surface and a backing plate capable of moving relative to said die cutting unit comprising a die cutter having at least one die cutter, and a mating plate for forming a body of the mold at a location selected in the planar substrate material in the area of the plastic foil used, wherein the sealing plate of the sealing unit has at least one set of convex and one set of concave surfaces facing the top of the backing plate to form a heat-reduced zone of the plastic sheet above the concave area and a drive for movement. Laminating material The laminating material is arranged to the die cutting unit so that the heat-reduced area aligns with the location of the die cutter during cutting, so that the cut is made only in the heat-reduced area. 2. The sealing and cutting unit of claim 1, wherein the sealing and cutting unit comprise a sealing unit coupled to a cutting unit of the mold. 3. The sealing and cutting unit of claim 2, wherein the cutting unit of the mold is positioned at the end of the sealing unit in the direction of the machining of the substrate material at a predetermined distance therefrom, and the sealing unit and mold body unit are controlled in a coordinated manner so that a selected position in the substrate material in the sealing unit enters a position above the lowering area and thereafter enters a corresponding position under the cutting knife in the cutting unit of the mold. 4. The sealing and cutting unit of claim 3, wherein a plurality of concave areas in the active surface of the sealing plate form a pattern which is an image of the cutter pattern of the plurality of molds of the cutting unit of the mold so that the two patterns are aligned. 5. The sealing and cutting unit of claim 3, wherein the planar substrate material is moved by a discrete driving path from the sealing unit into the cutting unit of the mold. 6. The sealing and cutting unit of claim 2, wherein the planar substrate material is moved by a discrete driving mechanism from the sealing unit into the cutting unit of the mold. 7. The sealing and cutting unit of claim 1, wherein the concave area of the sealing plate is wider than the die cutting blades of the die cutting unit so that the reduced heating area encircles the body of the die cutting unit on all sides. 8. The sealing and cutting unit of claim 1, wherein the sealing plate is formed from metal, wherein a path is made on its active surface to form a concave area, and wherein the active surface is coated with a scratch-resistant plastic material. 9. The sealing and cutting unit of claim 1, wherein it forms part of an assembly forming an opening for a packaging machine for packaging liquids and materials, the substrate being a sheet of carrier material prepared with a layer of plastics having a notch for producing a packaging material with a tear-off strip above the opening, and the form for the die-cutting knife being a circle. The sealing and cutting unit of claim 1, wherein the upper portion of the back plate is a flat portion.
