Definitions

  • the invention relates to a device for winding a new empty winding core to replace a full roll, with a continuous, uninterrupted via a feed roller, flexible web, which is in the winding position center distance to the full roll, with a tube feeder through which a new empty tube is brought into the winding position in circumferential contact and drive contact with the feed roller, in which it is partially wrapped around by the web stretched between the feed roller and the full reel, with a piecing guide on which a roller is loosely rotatably mounted axially parallel to the feed roller and of which the empty one The side facing away from the sleeve, the web being moved entrainingly in the direction of advance of the empty winding core over an interspaced web in its advancing direction, whereby the wrap angle of the web of the new winding core is increased to more than 180 degrees, with a knife, by means of which the web stretched across the space between the roller and the full core is cut and by means by which the new gate of the web, while continuing to wrap the empty core with a crease ahead
  • the material web can be woven or knitted fabrics, cloths and the like, as well as lattice-like plastic fabrics and foam.
  • a turning racket is provided, around the front edge of which the beginning of the new web is turned over.
  • the turning racket is then knocked into the gap between the feed roller and the new empty sleeve to be wound with the cover of the web.
  • the beginning of the web is driven into the gap with the folding edge formed by the envelope, until it is carried along between the feed roller and the new sleeve by the turning racket. Once this has been done, the turning racket is slid out of the envelope of the material web and thus also out of the gap.

  • the swivel racket is pivotally mounted.
  • the turning racket offers an inevitable guidance of the beginning of the new web of material until it is clamped and pulled at the end of the gap between the feed roller and the empty sleeve.
  • the invention has for its object to simplify a device of the type mentioned, in particular so that it can easily be adapted to different qualities in terms of flexibility, strength and the like, to be processed webs.
  • the invention is characterized in that a guide plate is arranged on the attachment guide, which extends over the entire width of the roller and at a radial distance from the circumference of the roller and over a portion of the circumference of the roller that the guide plate is at its front in the feed direction End has a front edge which extends axially parallel to the feed roller that the guide plate outside a guide surface for the has a new cut of the web on which it can be spread out and slide flat and that in the end position of the feed movement of the piecing guide the empty sleeve is wrapped by the web with a wrap angle of at least 240 degrees and the front edge of the guide plate with a radial distance to the circumference the empty sleeve and with a radial distance to the circumference of the feed roller, which is 0.3 to 2 times, preferably 0.7 to 1.3 times, the diameter of the roller.
  • the invention takes advantage of the fact that it is not necessary to safely guide the new web in the gap between the feed roller and the new sleeve, the web on the last piece of the feed movement, as in the known device, inevitably .
  • the beginning of the new web which is held ready on the guide plate, slides over the guide plate and thereby comes into contact with the web sections lying over the circumferential sections of the feed roller and the sleeve delimiting the gap.
  • the start of the new web which initially spans the gap, is drawn into the gap by the rotary movement of the feed roller and the sleeve, forming a fold.
  • the turning racket which has driven the beginning of the web into the gap in the known device described above, is no longer required. This also eliminates the very complex, fast-moving drive parts for this turning racket. Only one guide plate is required, which, on the other hand, has to be of simple design and moved slowly.
  • the new section of web slides under the influence of its weight and also of the decreasing tension in the gap as soon as it is cut off.
  • This sliding movement can affect the flexibility and weight, and the other qualities the processing web are coordinated by appropriate design and arrangement of the guide plate in its winding position. It is important that the web can be inserted in the desired manner by a sufficient distance at the front edge of the guide plate. Instead, it is necessary for a corresponding adaptation in the known device described at the outset to convert or convert the turning racket and its drive means.
