Patent number: 5503705Abstract: A device and process useful for producing a plurality of individual film composites is disclosed. A temperature-controllable roll serves as a sealing tool, on the circumferential surface of which a number of plastic film webs are sealed together under the application of pressure and heat. The plastic film webs come into contact with the circumferential surface of the roll at equal or varying distances from each other and are guided over pressure rolls. These pressure rolls contact the circumferential surface of the temperature controllable roll under pressure. The plastic film webs pass through the contact areas between the pressure rolls and the temperature controllable roll. The plastic film webs are provided on one or both sides with sealing layers, which are fused by the action of heat, so that sealing of the superposed laminated plastic film webs on the circumferential surface of the temperature controllable roll occurs.Type: GrantFiled: October 20, 1994Date of Patent: April 2, 1996Assignee: Hoechst AktiengesellschaftInventors: Sabine Rohleder, Jochen Coutandin, Burkhard Hoppe

Process for producing a multilayered film composite from thermoplastic, coextruded plastic film webs
Patent number: 5429696Abstract: A temperature-controllable roller 1 is used as the sealing tool, on whose circumferential surface a plurality of plastic film webs are sealed together under the action of heat and pressure. The plastic film webs, which are conveyed about compression rolls, run at equal or different mutual distances onto the circumferential surface of the temperature-controllable roller. These compression rolls rest against the circumferential surface of the temperature-controllable roller and exert pressure onto the latter. The webs of plastic film run through the contact nips between the compression rolls and the temperature-controllable roller. The plastic film webs are provided on one or both sides with sealing layers, which are incipiently melted by the action of heat, so that a sealing of the plastic film webs in layers one on top of the other occurs on the circumferential surface of the temperature-controllable roller.Type: GrantFiled: May 11, 1994Date of Patent: July 4, 1995Assignee: Hoechst AktiengesellschaftInventors: Sabine Rohleder, Jochen Coutandin -
Patent number: 5328536Abstract: Along a plane sealing zone, a number of plastic film webs are sealed together under pressure and heat application. The plastic film webs run at equal or different distances from one another into the sealing zone and are guided over compression rolls. Between the compression rolls, which lie opposite each other in pairs, the plastic film webs are introduced and subjected to both pressure and heat. The plastic film webs are provided on one or both sides with sealing layers, which are incipiently melted by the action of heat, so that a sealing of the plastic film webs in layers one on top of the other occurs in the sealing zone.Type: GrantFiled: October 22, 1993Date of Patent: July 12, 1994Assignee: Hoechst AktiengesellschaftInventors: Sabine Rohleder, Jochen Coutandin

Patent number: 5283017Abstract: A device and method of producing a multi-layer film composite is provided. In accordance with the device and method, a temperature-controllable or heatable roll serves as a sealing tool, on the circumferential surface of which a number of plastic film webs are sealed together under the application of pressure and heat. The plastic film webs come into contact with the circumferential surface of the roll at equal or varying distances from each other and are guided over pressure rolls. These pressure rolls are in contact with the circumferential surface of the heatable roll under pressure. The plastic film webs pass through the gaps between the pressure rolls and the heatable roll. The plastic film webs are alternately sealing layer-free or provided on one or both sides with sealing layers, which are fused by the action of heat, so that sealing of the laminated plastic film webs on the circumferential surface of the heatable roll occurs.Type: GrantFiled: November 5, 1992Date of Patent: February 1, 1994Assignee: Hoechst AktiengesellschaftInventors: Sabine Rohleder, Jochen Coutandin, Erna Kastl

Patent number: 5185832Abstract: Process for producing an optical coupler for polymer optical waveguides by arranging the optical waveguides in the same sense and bundling them by means of a plastic shrink-on sleeve. In this process, two to 10.sup.5 polymer optical waveguides are arranged in the same sense and bundled and a plastic tube is put over the mixing region. Then a piece of plastic shrink-on sleeve is pushed over the plastic tube and the shrink-on sleeve is heated to a temperature at which it contracts. The shrinkage temperature of the shrink-on sleeve is inside the thermoelastic temperature range of the plastic tube. The optical waveguide bundle may be stretched during or after heating.Type: GrantFiled: April 24, 1991Date of Patent: February 9, 1993Assignee: Hoechst AktiengesellschaftInventors: Jochen Coutandin, Jurgen Theis, Werner Groh, Andreas Brockmeyer
