Definitions

  • This invention relates to a process and apparatus for providing a web of paper, plastics material or the like, which web is intended for use in the manufacture of carrying bags, with U- Sl-IAPED CARRYING HANDLES MADE FROM ELON- GATED STRIPS OF PAPER OR PLASTIC MATERIAL BY FOLDING BOTH END PORTIONS THROUGH 90.
  • a striplike blank is moved to the folding cylinder parallel to the longitudinal axis of the same and is received by the grippers carried by said cylinder. This will result in a change of the direction of travel of the strip through 90 from the previous direction of travel.
  • the strip held on the folding cylinder is provided in a scoring station with score lines extending at an angle of 45 and facilitating the subsequent exact folding of the two strip end portions by means of a folding device.
  • the two strip end portions are folded out of the peripheral surface of the folding cylinder and turned through 90 opposite to the direction of travel with the aid of suitably arranged folding plates.
  • each carrying handle must be applied to the moving web at the trailing end of the web portion intended to make a carrying bag, so that the legs of the carrying handles lead the intermediate portion of the carrying handle in the direction of travel of the web.
  • the carrying handles are formed on the folding cylinder in that the strip end portions are folded oppositely to the direction of travel so that the carrying handles delivered by the folding cylinder have leading intermediate portions.
  • the completed carrying handles with a leading grip portion are moved into a stationary, magazine-like holder and this holder deflects each carrying handle from the folding cylinder and arrests each handle.
  • the magazine is arranged so that the exposed leg end portions of the U-shaped carrying handles are closely over the web, which is trained in this area over a reversing pulley and travels in a direction that is opposite to the direction of rotation of the folding cylinder.
  • a carrying handle is applied to the trailing end portion of the previously perforated web section.
  • the adhesive-coated leg end portions of the carrying handle are blown down by a suddenly initiated air stream onto the passing trailing end portion of the web section and are applied to the same by pressure rollers, which are swung down immediately thereafter, so that the carrying handles are pulled out of the magazine oppositely to their original direction of travel.
  • Two such carrying handles are applied in pairs one beside the other to the web of plastics material to lie opposite to each other on the inside surfaces of the tubing during the subsequent formation of the tubing.
  • the grip portions then lie on the inside of the leg end portions, as is desirable for the subsequent gripping.
  • Individual tube sections are then severed from the preperforated tubing and the leading end of each tube section is completely folded to form a bottom.
  • the applying process which is carried out with that apparatus has the disadvantage that the exposed leg end portions of the carrying handle in the magazine will not be at an exactly spaced distance from the web if the handle is slightly deformed so that an exact application of the carrying handles is rendered more difficult. Because the pressure rollers are swung down immediately after the handle leg end portions have been blown down, there will be in any case a relative movement between the adhesive-coated leg end portions which have been blown down and the web so that the latter is smeared. When the carrying handle is to be applied it must be accelerated from the standstill to the web speed. Depending on the web speed, this will result in smaller or larger inaccuracies in the application step and also in a smearing of adhesive. The different springback due to the 45 folds has also different effects on the forces which act as the carrying handle is pulled out of the magazine so that the inaccuracy of the application step may be increased.
  • the carrying handles formed on a folding cylinder and having leading grip portions are not arrested in a magazine and are not subsequently accelerated in the opposite direction but without an interruption of their travel are turned so that the originally trailing legs of the carrying handles lead as they are applied to the moving web.
  • the process according to the invention is characterized in that the strip is first gripped in known manner in its intermediate portion and the strip end portions are folded through opposite to the direction of travel of the strip, the resulting legs of the carrying handle are then gripped at their end portions and advanced further, whereas the intermediate portion is released, the carrying handles are then turned over through opposite to the direction of travel of the gripped ends and with their now leading legs are connected to the web moving in the same direction.
  • the process according to the invention results in a positive control of the carrying handle in each phase of the operation and enables a supply of the carrying handle to the web at the direction of travel of the latter.
  • This control of the carrying handle and the fact that a relative velocity between the carrying handle and the web during the application of the web is avoided will prevent an inaccurate positioning of the carrying handle just as a smearing of the web.
  • the carrying handles may be turned over in that they are moved past a stationary turning plate, such as is known for the folding of the legs of the carrying handles through 90.
  • An apparatus for carrying out this process may be characterized in that a known folding cylinder serving to fold the strip end portions through 90 is succeeded by a turning cylinder which rotates oppositely to the folding cylinder and which comprises a gripper for receiving and holding the carrying handles, which are supplied by the folding cylinder with trailing legs, and a stationary turning device for the carrying handles is disposed near the peripheral surface of the turning cylinder.
  • the turning cylinder receives the carrying handles, which are supplied from the folding cylinder with leading grip portions, and continues to move them initially with leading grip portions until the carrying handles are gripped by the turning device and by the latter are turned to extend opposite to the direction of travel whereas the gripped leg end portions continue to move with the turning cylinder.
  • Both gripper halves of the gripper of the turning cylinder are desirably movable and the trailing half is opened to receive the carrying handles whereas the leading half is opened to deliver the carrying handles to the web.
  • This operation will take into account the fact that the carrying handles extend forwardly in the direction of rotation of the turning cylinder as they are received and extend opposite to that direction of rotation as they are delivered.
  • the leading and/or trailing gripper half comprises a pressure contact member which is curved to conform to the peripheral surface of the turning cylinder. The pressure contact member of the leading gripper half ensures that the handle legs remain in pressure contact with the folding cylinder as they are received whereas the free end portions are folded into the gripper opening, e.g., by
  • the web e.g'., by adhesion, are forced against the web.
  • the turning device associated with the turning cylinder may desirably consist of a guide plate which extends around part of the periphery of the turning cylinder and which adjacent to the receiving zone has a width corresponding to the overall width of the carrying handles whereas the width of said plate in a succeeding portion is smaller than the, distance between the inside edges of the carrying handles, and glue-applying segments for applying glue tothe adheringtportions of the carrying handle legs are provided in the latter portion.
  • glue-applying segments for applying glue tothe adheringtportions of the carrying handle legs are provided in the latter portion.
  • the turning cylinder is so driven by a varying ratio transmission that it rotates at the peripheral velocity of the folding cylinder as it receives the carrying handles and at the web' velocity as it delivers the carrying handles, the web velocity being variable independence on size.
  • the varying ratio transmission may 'suitably consist of a cam-controlled differential gear having a cam which is selected in dependence on size- If a folding knife is provided on the folding cylinder to introduce the leg end portions of the carrying handles into the gripper of the turning cylindenthe end portions of the legs of the carrying handles musthave a relatively large fold-in length allowance because the folding gripper, cannot be closed until the folding knife has .been withdrawn from the gripper and the end'portions of the legs of the.
  • the trailing gripper half is adapted'to be moved out of the peripheral surface of the turning cylinder when it is opened so that this gripper half serves also to infold theend portions of the legs of the carrying handles because the jaw of that gripper half is disposed above the .leg end portions during the opening move'mentof the gripper and pulls in these end portions between the jaws as'the gripper is closed.
  • the trailing gripper half may suitably be mounted on a slider, which is movableby means of a stationary control cam in a substantially radial guide slot.
  • the guide slot may be so designed that the trailing gripper half is lifted from the peripheral surface of the turning cylinder as the gripper is opened and at the same time moves in the peripheral direction from the leading gripper half.
  • the same eflect can be produced by a strictly radial movement of the trailing I folding jaw but the latter will have to be lifted considerably in this case to ensure that the leg end portions are received under the jaw.
  • the trailing gripper half may also be pivoted to the turning cylinder on an axis which is highly eccentric relative to the axis of the turning cylinder and succeeds the gripper opening in the direction of rotation.
  • the folding cylinder may be provided with additional grippers for gripping theend portions of the legs of the carrying handles when these end portions have initially been turned over the rear whereas the intermediate portion of the carrying handle is gripped by the gripper and is released by it when said end portions are gripped by the additional grippers.
  • the carrying handles will then have to be held by a turning plate and turned rearwardly as the movement of the gripped end'portions of legs of the carrying handlesis continued.
  • the use of a turning cylinder has the advantage that the design will be simplified. Besides, the use of the apparatus which has been described hereinbefore will cause the intermediate portions of the handles to lie on the other side of the handle legs. 7
