Definitions

  • the invention relates to a device for severing a web of material running to a driven winding roll and for fixing the trailing start of the web on a winding core or a winding tube with a winding roller leading the web to the winding roll, to which a winding tube can be adjusted, with a knife cutting the web and with means for redirecting the start of the web from the winding roller to the driven winding tube.
  • Continuously produced material webs for example flat-lying tubular webs produced in a blown film line or single-layer webs made of thermoplastic material, must be wound up into winding rolls for storage and handling.
  • the web running to a winding roll must be cut after the winding of a winding roll has been finished and the beginning of the web of the trailing web must be set for winding on a winding core or a winding tube in order to be able to continue the winding process without disturbing or redirecting the continuously fed web. It is known to wind up the beginning of a web to be wound into a winding roll on a winding tube which is provided with an adhesive application to fix the beginning of the web.
  • a known device for adhesive-free winding of a beginning of a web on a winding core or a winding tube consists of a winding tube attached to a feed roller provided with suction bores in its jacket, onto which, after the web has been severed, the beginning of the web thus formed is wound up by the fact that in the nip a suction box is inserted between the feed roller and the winding tube, which is provided on an extended edge with a knife that cuts the web and then on the blade with a shell-shaped curved wall that forms a shell-shaped curved channel with a region of the circumference of the winding tube whose front end in the area of the nip is sucked in air by the suction box in such a way that the beginning of the web is sucked into the guide channel, and thereby is fixed to the winding tube that the beginning of the web enters the gap between the feed roller

  • a particular problem with the winding of winding cores or winding cores with a start of the web is, however, that the webs to be wound into winding rolls are asymmetrical, which means that they have sides with different properties.

Abstract

L'invention concerne un dispositif permettant de séparer une bande roulant en direction d'un rouleau de bobinage entraîné et de fixer le début de la bande qui suit sur l'axe de bobinage ou sur un mandrin de bobinage. Ledit dispositif comprend un cylindre de bobinage guidant la bande jusqu'au rouleau de bobinage, cylindre sur lequel un mandrin de bobinage peut être monté, une lame séparant la bande et des moyens pour dévier le début de la bande du cylindre de bobinage sur le mandrin de bobinage entraîné. Afin de permettre de manière simple, sans application d'adhésif, d'enrouler le début d'une bande, dégagé par coupe, des rouleaux inverseurs montés sur des supports sous forme de pinces peuvent être insérés dans l'espace entre cylindre entre le cylindre de bobinage et le mandrin de bobinage monté dessus, au moins une bande sans fin passe par lesdits rouleaux inverseurs, ladite bande entourant et serrant la partie de mandrin de bobinage (4) opposée au cylindre de bobinage, au moment où les rouleaux inverseurs sont introduits dans l'espace entre cylindres (10). Le cylindre de bobinage est muni d'une lame de séparation pouvant être sortie d'une fente située dans une génératrice et comporte dans le sens de rotation derrière la lame de séparation, un dispositif insérant le début de la bande résultant de la coupe de séparation, dans la fente entre le mandrin de bobinage et la bande passant sur le mandrin de bobinage par l'intermédiaire des rouleaux inverseurs.
