  • the present invention relates to difi'erent width reels (i.e. reels having different flange member spacing) on which corresponding width strips of web material can be wound and, more particularly, to different width reels which are adapted to be supported on a spindle in a manner such that the longitudinal center line of each wound strip (regardless of width) will be disposed at the same location with respect to the spindle. Moreover, this invention relates to a mounting for securing different width reels respectively on a spindle, in the foregoing manner.
  • this spindle in addition to the stepped shoulders, includes a separately formed spring and detent which are connected to the spindle for the purpose of respectively securing the different width reels on the spindle. More specifically, the detent is pivotally mounted on the spindle and spring biased for engagement with a tab on each of the difierent width reels.
  • Such a mounting could, for example, include a detent member which is integrally formed with the reel and adapted to cooperate with an engageable portion of the spindle for securing the reel on the spindle so that the longitudinal center line of a web wound on the reel will be disposed at the same position with respect to the spindle regardless of the corresponding web and reel widths.
  • a detent member which is improved so as not to rely on a separate spring for movement to engage the spindle.
  • This detent member could, for example, be resiliently flexible and integrally formed with the reel hub.
  • Yet another object of the present invention is to provide a reel on which web material can be wound and which is adapted to be supported on a spindle in a manner such that, regardless of the reel width, the longitudinal center line of a wound web will occupy the same position with respect to the spindle.
  • a further object of the present invention is to provide a reel construction for accomplishing the foregoing objectives and which is readily and inexpensively fabricatable.
  • a reel for web material including two spaced opposed flange members and a hub member which supports the flange members in their spaced relation.
  • the reel hub is provided with an opening adapted to receive a drive spindle for rotation of the reel.
  • a flexibly movable finger member of the reel hub is supported, in a cantilevered manner, within a hub slot which communicates with the hub opening.
  • This finger member has a cam detent which is adapted to impart flexing movement to the finger member and to engage an engageable portion of the drive spindle for securing the reel on such spindle.
  • cam detent is disposed at a location which is substantially midway between the reel flanges, reels of the foregoing kind having different flange member spacing for supporting various width webs can be respectively located on the drive spindle in a manner whereby the longitudinal center line of each supported web will be disposed in the same position with respect to such spindle.
  • the hub member is provided with an outer tubular portion which supports the flange members and with an inner core portion which is disposed within the tubular portion in radially spaced relation.
  • the hub opening adapted to receive the drive spindle for rotation of the reel, is disposed in the core portion. Therefore, the torque effected by the drive spindle is absorbed by the core porn'on and will not be transmitted to the reel flanges since such flanges are separated from the core portion.
  • FIG. 1 is a perspective view of a reel for web material in accordance with a preferred embodiment of the present invention, showing a portion of the reel broken away to best illustrate certain details of the reel;
  • FIG. 2 is an underside view of the reel depicted in FIG. 1;
  • FIG. 3 is a section view of the reel as viewed along the line 33 in FIG. 2, further showing the reel mounted on a spindle for rotation therewith;
  • FIGS. 4, and 6 are perspective views of three different kinds of spindles with which the reel is adapted to be used.
  • center plane as used hereinafter with reference to a reel of the kind including a hub member and spaced opposed flange members is intended to define that plane which is perpendicular to the longitudinal axis of such reel and equally distant from the reel flanges.
  • a reel 1 including a hub member 2 on the opposite ends of which are disposed generally circular flange members 3 and 4 in substantially parallel, spaced opposed relation.
  • the reel hub 2 has an outer tubular portion 5 supporting the reel flanges 2 and 3 and an inner core portion 6 concentrically located within the tubular portion and radially spaced inwardly from the last-mentioned portion.
  • a ring-like base portion 7 of the reel hub 2 supports the outer and inner hub portions 5 and 6 in their spaced relation so that an open, annular channel 8 is thereby defined.
  • the hub core 6 is provided with an outer annular wall 9 and a spaced inner wall 10 having a substantially square cross-sectional configuration which defines an elongate opening or bore 11 in the hub core.
  • the opening 11 is uniformly disposed about the longitudinal axis of the reel 1 and, as will be described hereinafter, is adapted to receive any one of several different kinds of spindles on which the reel may be respectively secured for rotation.
  • a slot 15 on the outer hub portion 5 of the reel 1 is disposed in radial alignment with openings 16 and 17 in the reel flanges 3 and 4, see FIGS. 1 and 2.
  • This slot 15 is of dimensions suitable for the receipt of web material (not shown). Accordingly, to thread web material onto the reel 1, a leading web end is passed in edgegiiding relation between the reel flanges 3 and 4 into the slot 15 and thence into the annular channel 8.
  • the web material is wound about the outer hub portion 5 between the reel flanges 3 and 4 so as to cinch or snub the web to such hub portion.
  • FIGS. 4, 5 and 6 drive spindles 18, 19 and 20, the first of which has a substantially square cross-sectional configuration and the remaining two of which have a substantially circular cross-sectional configuration.
  • Each of the spindles 18, 19 and 20 is of dimensions suitable to be received in the hub core opening 11 of the reel 1 in the manner illustrated by FIG. 3 and is provided with a collar base 21, 22 and 23 on which the reel can be seated.
  • the collar bases 21, 22 and 23 are preferably adjustable along the spindles 18, 19 and 20 to accommodate difierent width reels.
  • Peripheral recesses or grooves 24, 2S and 26, the significance of which will become apparent hereinafter, are located between the opposite ends of the spindles 18, 19 and 20.
  • One of the spindles 20 difiers from the other two spindles 18 and 19 in that the spindle 20 is further provided with a key member 27 which is adapted to be received in the key channel 12 of the reel 1.
  • the inner wall 10 of the hub core 6 is provided with a slot 28 which extends through the previously described center plane of the reel.
  • This finger member 29 is supported within the slot 28 in a cantilevered manner such that the cam detent 31 lies midway between the reel flanges 3 and 4 and is movable in the center plane of the reel 1 towards and away from the longitudinal axis of such reel.
  • the cam detent 31 extends radially inwardly toward the reel axis and is of sufficient radial extent and appropriate surface configuration to be received in each of the peripheral recesses 24, 25 and 26 of the spindles 18, 19 and 20 upon receipt of such spindles respectively in the hub core opening 11.
  • the cam detent 31 upon first placing the reel 1 on any one of the spindles 18, 19 and 20, the cam detent 31 will abut against the spindle surface so as to be slightly moved outwardly away from the reel axis (together with the resiliently flexible finger member portion 30) against the normal urging force of the last-mentioned portion.
  • the cam detent 31 When a spindle is fully received in the hub core opening 11, as illustrated in FIG. 3, the cam detent 31 will be moved back to such illustrated position by the normal urging force of the finger member portion 30 and there will be so held in tight abutment against the spindle at the spindle recess.
  • the driving torque effected by such rotating spindle will be absorbed by the hub core 6 and will not be transmitted to the reel flanges 3 and 4, since these flanges are separated from the hub core by the annular channel 8. Furthermore, since the cam detent 31 is disposed in the center plane of the reel 1 and is thus located midway between the reel flanges 3 and 4, reels of the foregoing kind having different flange member spacing, i.e.
  • FIG. 3 shows the reel 1 in full line and another reel 1 in broken line.
  • the reel 1 is identical to the reel 1 but for a smaller width dimension.
  • each of the reels 1 and 1' can be supported on the spindle 19 (or the spindles 18 and 20) with the center planes of the different width reels in the same position with respect to the spindle.
  • the reel 1 preferably comprises a single unitary form and, therefore, need not be assembled piece-wise as in the previously described prior art instances.
  • the reel 1 may be secured on a spindle in either of two orientations. That is to say, the reel 1 may be secured on the spindles 18, 19 and 20 so that either one of the reel flanges 3 or 4 is disposed in contiguous relation with the spindle collars 21, 22 and 23, see FIG. 3.
  • the reel 1 is adapted for use with several different kinds of spindles.
  • the cam detent 31 on the finger member 29 serves to secure the reel 1 on each of the spindles 18, 19 and 20 for synchronous rotation respectively therewith.
  • the key member 27 of the spindle 20 and the substantially square cross-sectional configuration of the spindle 18 also serve to secure the reel 1 for such rotation.
  • a hub member having a longitudinal axis and a plane disposed substantially perpendicular to said hub member axis;
  • said hub member including:
  • a finger member including an elongate portion flexibly movable within said slot and a cam detent adapted to impart flexing movement to said finger member and to engage the engageable portion of such a spindle;
  • a hub member having a longitudinal axis and a plane disposed substantially perpendicular to said hub member axis;
  • said hub member including:
  • a finger member including an elongate portion flexibly movable within said slot and a cam detent disposed in angular relation to said elongate portion and adapted to impart flexing movement to said finger member and to be received in the recess defining the engageable portion of such a spindle for engagement with the last-mentioned portion;
