Definitions

  • ABSTRACT A web support moves about the drive drum from a [52] US. Cl. 242/56 R, 83/557 [51] Int. B65h 19/26 parked position to a iti supporting the web mate- [58] held of Search' 242/56 56 A; 83/337 rial away from the drive drum.
  • a toothed knife then 83/557 severs the web, with the teeth of the knife being received in complementary grooves in the web support so that the knife contacts only the web.
  • the present invention provides a cutting means for use on continuous web winding machinery, such as the single drum winder illustrated.
  • the cutting means of this invention is particularly well adapted for cutting thick and resistant materials.
  • a web support is mounted for rotation in a circular path about the surface of the drive drum of the single drum winder.
  • the web support moves from a parked position where it is out of contact with the web to a cutting position intermediate the nearly full roll, presently being wound, and the new core onto which the web is to be transferred. ln this position the web support removes the web from contact with the corresponding region of the drive drum.
  • a knife is mounted above the drive drum for movement toward the web'support when the web support is in the cutting position.
  • the knife has a plurality of teeth on the leading edge thereof which serrate the web of material and thus provide a much more effective cutting action than with a straight, flat blade.
  • a plurality of channels in the web support receive the knife teeth therethrough in complementary fashion, and enable the teeth to penetrate the web by passing into the channels during the cutting action. At no time, however, does the knife actually contact anything but the web. The knife teeth never touch the web support, the drive drum, the nearly full roll, nor the new core.
  • the web support thus provides firm support for the web during the cutting action while the complementary arrangement of the web support channels and the knife teeth permits the supported web to be cut without knife contact against anything but the web itself.
  • FIG. 1 is a partial view of a continuous single drum winder apparatus, showing the web cutting means in the parked position;
  • FIG, 2 is a view similar to FIG. 1, showing the web support advanced to the cutting position;
  • FIG. 3 shows the knife and web support cooperating to sever the web for transfer onto a newv core
  • FIG. 4 shows the web support and knife returned to the parked positions and the new core partially ad vanced to the position of the earlier full roll
  • FIG. 5 is an enlarged fragmentary view of the cutting action of the knife relative to the web support, showing successive knife positions, and i FIG. 6 is a cross sectional view of the knife and web support taken generally on line 66 of HG. 5.
  • Winder 10 is thus of conventional design and includes a drive drum 12 for driving a web 13 onto a take up roll 15 at constant roll surface speed.
  • a pair of primary arms 17 supports a new core 19 for starting a new roll-when roll 15 is full.
  • the present invention provides a cutting means including a knife 20 and a web support 25.
  • Web support 25 is movable from a parkedposition (FIG. 1) to a cutting position (FIG. 2) where the web support is then located between drum l2 and web 13.
  • the web support cutting position places the web support in the path of the cutting stroke from knife .20, and supports the web material away from drum l2 toassist knife 20 in cutting the web.
  • the cutting action of the knife' is further enhanced by the provision of teeth 27 on the leading edge of the knife, and the provision of complementary channels 28 within web support 25 (FIG. 6).
  • the teeth arethus able to penetrate through and to cut the web in a multiplicity of locations, effectively serrating the web, while the web support continues to support the web between the teeth.
  • the tooth and channel configuration also enables knife 20 to cut through web 13 without contacting the web support 25 itself. Further, the movement ofweb 13 away from drum 12 and over web support 25 provides an open space 31 just before web support 25 and above drum 12 into which the knife 20 may move, during completion of the cutting action, without contacting drive drum 12. As a result, the knife is able to remain totally free of contact with the web support, drive drum, core, roll, and other portions of winder 10. Wear of knife 20 and web support 25 is thus minimized, while the web cutting means of this invention is able to cut even the most thick and resistant of web materials.
  • This invention therefore includes means for moving the web support 25 from the cutting position, where it is between the drum 12 and web 13, and in supporting contact with the web, to a parked position (FIG. 1), where the web support is free of contact with web 13.
  • a pair of web support arms 35 supports web support 25 for rotational movement in a single direction about the axis of rotation of drive drum l2 and adjacent to the surface thereof.
  • An appropriate drive means 36 is connected in conventional fashion to web support arms 35 to move web support 25 as desired.
  • the cutting and roll changing sequence thus proceeds as follows. Starting with FIG. 1, the roll 15 is nearly full and web 13 must shortly be transferred to a new core 19. Web support 25 is therefore moved from the parked position of FIG. 110 the cutting position of FIG. 2, following which the new core 19 is moved down to drive drum l2 and brought up to speed (FIG. 3).
  • the knife strikes the web rapidly (FIG. 3) and the severed web is transferred to the new core 19 by conventional means, such as an adhesive on the new core.
  • the cutting action of the knife is illustrated in detail in FIG. 5, where successive positions of the knife are shown as it moves toward the web support and as the knife teeth move through the web support channels.
  • this invention has numerous advantages. Due to the support provided by the web support 25 and due to the teeth 27 on the leading edge of knife 20, even the thickest and most resistant of materials can be cut quickly, cleanly, and efficiently. The cutting action is far more effective than would be possible if the web were unsupported. At the same time, however, the complementary nature of the knife teeth and web support channels join with the open space 31 to enable the knife to strike the web power- 4 fully and sharply while the knife itself remains totally free of contact with any other portion of the winder 10 machinery. Thus wear of the knife and knife teeth is minimized; damage to the web support and to the drive drum is avoided; and undesirable cutting actions against either the full roll or the new roll are prevented.
  • the web support is easily movable into the cutting position when the transfer cycle is to be initiated, and is readily storable in the parked position during the remainder of the winding cycle. This minimizes frictional wear and heating of the web support. Further, the web support easily and automatically moves beneath the web, when moved into the cutting position, and cycles in such a fashion that'it also easily avoids interference with both the full roll and the new core.
  • An additional advantage of this invention is that the web support and knife are easily useable in a broad range of web handling machinery, to provide a substantial improvement in the ability thereof to. handle difficult webs of the nature described.
  • a continuous winder for web material including a frame, a driven drum supported in the frame for driving the roll being wound, main support means on the frame for supporting such roll in driven position with respect to the drum, and primary support means for re-' d.
  • said web support supporting means further comprises'means for moving said web support about the axis of the drive drum.
  • a continuous winder for web material including a frame, a driven drum supported in the frame for driving the roll being wound, main support means on the frame for supporting such roll in driven position with respect to the drum, and primary support means for receiving and supporting a new core in starting position with respect to the drum, the improvement comprising:
  • a knife for cutting the web said knife having a plurality of teeth on the leading edge thereof,
