  • the cross-cutting and Anwickelvorgang takes in this known device is relatively long.
  • Another disadvantage is that with this known device an envelope-free winding of the tail to the winding tube is not possible.
  • the invention the technical problem of providing a device of the type mentioned above, which is relatively simple and inexpensive, with a speedy Quertrenn- and Anwickelvorgang is possible and with an unencumbered Anwickeln to the winding tube is guaranteed.
  • the invention teaches a device for cross-cutting and winding a fed material web, in particular plastic film web to a winding tube in the course of winding the continuous material web to coils, wherein a Anwickel driven is provided, in which the winding tube is introduced for winding, wherein the Anwickel Hughes has a the winding tube to form a flow gap partially surrounding Leitschale, wherein a separating device for the transverse separation of the material web is connected to the guide shell, wherein the Anwickel insightful further comprises a Einblas driven, with the air with the proviso in the flow gap is inflatable that the tail formed by the transverse separation is sucked into the flow gap and on the winding tube is anwickelbar and wherein an electrostatic charging device is provided for improving the adhesion of the tail to the winding tube.
  • the continuous fed material web or plastic film web is separated in the course of the finish winding of a coil by means of the separating device.
  • the finished wound coil is then expediently removed with the wound-up trailing end.
  • the leading tail of the cross-separated material web is wound on a newly wound winding tube.
  • the winding tube is rotated during Anwickelvorgang or driven in rotation.
  • an air flow of high flow energy is introduced or blown into the flow gap, so that at the entrance of the flow gap, a negative pressure is generated, through which the tail is drawn into the flow gap. Due to the additional electrostatic charging according to the invention an optimal adhesion of the retracted tail to the winding tube is achieved.
  • the invention is based on the recognition that on the one hand it is of great advantage that the separating device is connected to the guide shell for the transverse separation of the material web or is part of the guide shell.
  • the electrostatic charge is of very particular importance.
  • this combination ensures a very rapid and immediately reliable threading to the new winding tube.
  • it is possible to work with an overall higher winding speed and, above all, an envelope-free winding can be realized in a functionally reliable manner.
  • the Leitschale is connected to the connected separating device expediently pivoted to the newly wound winding tube, so that the material web or plastic film web is severed with the separation device.
  • the material web is guided over the winding tube and the guide shell with the connected separating device is pivoted or pivoted to the winding tube, so that the material web is traversed in the conveying direction behind the winding tube of the separator.
  • the cross separation takes place with rotating winding tube. Swiveling the guide shell to the winding tube means, moreover, that a gap corresponding to the flow gap between the winding tube and the guide shell remains.
  • the separator is firmly connected to the Leitschale.
  • the separating device is thus movable or pivotable together with the guide shell.
  • a very particularly preferred embodiment of the invention is characterized in that the separating device connected to the guide shell is a chopping blade.
  • the separating device is a serrated knife or a cleaver designed as a serrated knife.
  • the design as a chopper or as a javelin knife has proven particularly useful in the context of the invention.
  • a particularly reliable and precise Anwickeln is possible if processed with a firmly attached to the Leitschale chopping knife or serrated knife and in combination to continue the electrostatic charge is realized.
  • the air is blown or introduced into the flow gap in the region of the separating device. It is advisable to air high flow energy or high flow rate.
  • injection device means on the one hand a device with which the air is blown into the entrance of the flow gap.
  • this also means a suction device which draws or sucks air into the flow gap, so that the negative pressure already described is generated at the inlet of the flow gap.
  • the injection device is part of the guide shell or is connected to the guide shell. According to a particularly preferred embodiment of the invention, the injection device is a transvector.
  • Transvector means in the context of the invention a slot nozzle, which expediently extends over at least the greater part of the width of the material web and preferably extends over the entire width or virtually the entire width of the material web. From this slot nozzle an air curtain high flow energy or high flow velocity is imitated and injected into the flow gap, so that the negative pressure at the entrance of the flow gap is formed. As a result, the web end of the transverse separated running material web is drawn into the flow gap (injector principle) and the web end is applied to the new winding tube.
  • electrostatic charging in the context of the invention is of particular importance in combination with the other features according to the invention.
  • the electrostatic charging device is expediently at least one charging electrode.
  • a very preferred embodiment of the invention is characterized in that the newly wound winding tube is charged electrostatically with the electrostatic charging device. This way you can particularly functionally safe winding of the tail to the winding tube can be achieved.
  • the material web or film web is charged electrostatically.
  • the tail is incidentally to the (otherwise) unprepared - wrapped in particular winding-free - winding sleeve.
  • the winding sleeve-side surface of the guide shell is porous or microporous.
  • the invention is based on the finding that a very rapid cross-cutting and Anwickelvorgang can be realized with the device according to the invention.
  • the tail can be wrapped with the device according to the invention very reliable function on a newly wound winding tube.
  • the Anwickeln in contrast to known from the prior art measures envelope can be realized.
  • the device according to the invention is further characterized by a simple and inexpensive structure. Therefore, in comparison to known from the prior art devices advantageously less expensive maintenance and repair measures are necessary.
  • a particular advantage lies in the fact that even existing or in operation winding systems can be equipped with the components of the invention. As a result, surprisingly simple, rapid and precise winding is possible with the device according to the invention.
  • a device for cross-cutting and winding a supplied material web to a winding tube 1 in the course of winding the continuous material web to coils 2 is shown.
  • the web is preferably a plastic film web 3.
  • the web 3 is guided around a contact roller 4 in the exemplary embodiment and then passes over a new winding tube 1 to be wound, which is introduced into an application device 5 for winding.
  • This Anwickel Anlagen 5 has a Leitschale 6, which surrounds the winding tube 1 in the Anwickelposition shown in the figures partially. Between winding tube 1 and 6 Leitschale a flow gap 7 is formed in the Anwickelposition.
  • a separating device for the transverse separation of the web 3 is connected to the guide shell 6.
  • the separating device is preferably, and in the exemplary embodiment, a chopper designed as a serrated knife 8.
  • the guide shell 6 is pivoted to the connected serrated knife 8 to the winding tube 1 and thereby the guided over the winding tube 1 web 3 is severed.
  • the pivoting mobility of the guide shell 6 has been indicated by an arrow.
  • the Anwickel adopted 5 further comprises a provided on the guide shell 6 blowing device 9, with the air high flow energy or high flow velocity in the flow gap 7 is inflatable. The leading end formed by the transverse separation is thereby sucked into the flow gap (injector principle) and in this way a functionally reliable winding on the winding tube is effectively supported.
