Patent name for equipment for gluing two packaging material patents T.T. Laval Shareholding Finance Co., Ltd. Principal Applicant Address Swiss Ply Inventor M. Gajusky; M. Huen; M. Mu Le.; F.M.; K. Spechit (patent) No. 03814246.5 Date of Application 2003.06.06 Approval Date Approval Notice No. 1662437 Date of Publication Approval 2005.08.31 Instruction Manual CD-ROM D0535 Main Classification Number B65H19/18 Classification Number B65H19 /18 Subsequent to the original application number priority item 2002.6.13 DE 10226148.2 Abstract This invention discloses a device for the gluing of two packaging material sheets (3, 4) for producing liquid-tight containers, each material sheet (3, At least one surface of 4) is coated with a liquid-tight, heat-activated adhesive layer. The device comprises means (5, 21, 27) for gripping the material sheets (3, 4), a cutting mechanism (11) for producing an oblique cutting face running substantially perpendicular to the material sheets (3, 4) and A welding unit (30) which applies heat and pressure along the adhesive sheet to glue the material sheets (3, 4) together. In order to provide an effective surface of the material plate with a very good quality of effective bonding sites and to guarantee an improved and more reliable liquid tightness when replacing the empty reel with a new full reel, the welding unit (30) is provided with an edge A carriage with a transverse rail (28) that is substantially perpendicular to the running direction (9) of the material plates (3, 4), a heater (33) mounted on the carriage and said heating in the direction of movement Pressure roller after device (33). Sovereignty item 1. A device for gluing two sheets of packaging material (3, 4) for the production of liquid-tight containers, in particular for liquid-sealed containers of liquid foods, wherein the sheets of material (3, 4) are at least one The side is covered with a liquid sealing adhesive layer (58, 65) that can be activated by heating, the device comprising: clamping means for fast clamping of the material plates (3, 4) (5, 21, 27) ), a cutting unit (11) for applying an inclined cutting surface (16) extending substantially transversely with respect to the material plates (3, 4), and for applying a glue material plate along the adhesive band (3) (3) , 4) A welding unit (30) for heat and pressure, characterized in that the welding unit (30) has a running direction with respect to the material plate (3, 4) along a transverse guide (28) ( 9) A skidder (31) moving substantially laterally, on which a heating device (33) is provided, and followed by a pressure roller (38) along the direction of movement (20).
