Definitions

  • ABSTRACT A web severing apparatus is adapted for use with flexible web material of a kind (a) which is to be withdrawn from a web holder and (b) which has a trailing end portion anchored to the web holder and a free leading end portion.
  • the apparatus includes a web pulling mechanism for pulling such web material, in either of first and second different orientations, longitudinally along a web path from the web holder. When substantially all but the trailing end portion of such web material is withdrawn from the web holder, the web pulling mechanism serves to shift a particular web portion which closely precedes the trailing web end portion laterally out of the web path.
  • a web cutter blade in the apparatus is disposed to sever the free leading web end portion from a remainder ofsuch web material at the web holder, in the event the web material is initially pulled in the second orientation along the web path. Also, the web cutter blade is disposed to sever such web material at the particular web portion which closely precedes the trailing web end portion, when substantially all of the web material has been withdrawn in the first orientation from the web holder and the particular web portion is shifted out of the web path.
  • the present invention relates to apparatus for severing web material and, in particular, to web severing apparatus which is adapted to sever web material generally in response to the state of withdrawal of such material from a web reel, web cartridge, or other web holder.
  • control mechanism detects the presence of the web hole upon withdrawal of the particular web portion from the web holder.
  • the web pulling mechanism will be deactuated in response to substantially completed withdrawal of the web material from the web holder.
  • the web material is manually severed at the particular web portion so as to separate the withdrawn web from the anchored 'web end portion. Accordingly, whiletheapparatus is adapted to stop pulling of the web material away from the web holder on the occurrence of substantially completed web withdrawal, no means-is included in the apparatus for thereafter automatically separating the withdrawn web from the anchored web end portion.
  • the web material to be withdrawn from the web holder is provided with two opposite surfaces which must be oriented in a givenrelative mannerduring such web withdrawal.
  • the film strip preferably should be oriented so that the base surface which is inert, rather than the emulsion surface which is sensitive, will abut against at least the majority of web guiding shoes and rollers in the processor. This is to reduce the possibility of scratching or marring the emulsion surface of the film strip, in the processor.
  • the previously described apparatus for stopping web movement in the event of substantially completed withdrawal of the web material from the web holder cannot satisfactorily be used in' the present example, because the film strip should be advanced without interruption from the web holder to the film processor.
  • such apparatus does not include means for distinguishing between withdrawal of the film strip, in desired and undesired orientations, from the web holder.
  • the film strip may be withdrawn from the web holder and ushered into the film processor in a manner causing the film emulsion surface to abut against most of the web guiding shoes and rollers in the processor.
  • apparatus has been devised in accordance with the present invention (1) which is adapted to automatically sever a leading end portion of the web material from a remaining web length upon initial withdrawal of such leading web end portion, in an undesired orientation, from the web holder and (2) which is adapted to automatically sever the. web material from a trailing web end portion, anchored to the web holder, upon substantially completed withdrawal of the web material, in a desired orientation, from the web holder.
  • a general object of the invention is to provide apparatus for severing web material in response to the condition of withdrawal of such material from a web holder.
  • Another object of the present invention is to provide web severing apparatus which is-adapted to sever a leading end portion of the web material from a remaining .web length upon initial withdrawal of such leading web end portion, in an undesired orientation, from a web holder.
  • Yet another object of the present invention is to provide web severing apparatus which is adapted to sever the web material from a trailing web end portion, anchored to the web holder, upon substantially completed withdrawal of the web material, in a desired orientation, from the web holder.
  • a further object ofthe present invention is to provide web severing apparatus which is adapted both to (l) sever a leading end portion of the web material from a remaining web length upon initial withdrawal of such leading web end portion, in an undesired orientation, from a web holder and (2) sever the web material from a trailing web end portion, anchored to the web holder,
  • a web severing apparatus adapted for use with flexible web material of a kind (a) which is to be withdrawn from a web holder and (b) which has a trailing'end portion anchored to the web holder and a free leading end portion.
  • the apparatus includes a web pulling mechanism for pulling such web material, in either of first and second oppositely twisted orientations, longitudinally along a web path from the web holder.
  • the web pulling mechanism serves to shift a particular web portion which closely precedes the trailing web end portion laterally out of the web path.
  • a web cutter blade in the apparatus is disposed to sever the free leading web end portion from a remainder of such web material at the web holder, in the event the web material is initially pulled in the second twisted sense along the web path. Also the web cutter blade is disposed to sever such web material at the particular web portion which closely precedes the trailing web end portion, when substantially all of the web material has been withdrawn in the first twisted sense from the web holder and the particular web portion is shifted out of the web path.
  • FIG. 1 is a perspective view of a web bearing cartridge, a web material being withdrawn from such cartridge, and a web severing apparatus in accordance with a preferred embodiment of the present invention
  • FIG. 2 is a fragmentary view of the web severing apparatus depicted in FIG. 1 (the web bearing cartridge being omitted), showing the manner in which the web material is severed in response to substantially completed withdrawal of such material from the cartridge;
  • FIG. 3 is a perspective view similar to FIG. 1, showirig the manner in which the web material is severed in response to initial withdrawal of such material, from the web bearing cartridge, in a web orientation different from that depicted in FIG. 1..
  • the core 3, in the present illustration, is adapted to support a convoluted roll of photographic film strip material 4.
  • the film strip 4 is wound about the core 3 in a manner such that an emulsion surface 5 of the film strip is located on the interior side of a strip convolution and a base surface 6 of the film strip is located on the exterior side of the same convolution.
  • the film strip 4 may be withdrawn from the cartridge 1 through a strip egress opening 7 in the cartridge body 2 (by means known in the art).
  • a trailing or rearmost end portion 8 of the film strip 4 is anchored to the core 3 by four strip engaging lugs 9, so that a substantial force would be required to separate the trailing film strip portion from the core.
  • FIG. 3 a support plate 10 on which is received the web roll cartridge 1.
  • Several cartridge positioning bars 1 1, fixed to the support plate 10, serve to firmly seat the cartridge 1 for withdrawal of the film strip 4 through the cartridge opening 7.
  • a free leading end portion 12 of the film strip 4 is first threaded about three idler rollers 13, 14 and 15 which are mounted on the support plate 10 in spaced relation. Once threaded about the idler rollers 13-15, the film strip 4 is passed through an opening 16 to rotate in a counterclockwise direction generally indicated by the arrow 21 in FIG. 3.
  • successive portions of the film strip 4 will be pulled longitudinally from the cartridge 1 and, in order, about the idler rollers 1'3, 14 and 15.
  • the idler rollers 14 and 15 are mounted on the support plate 10 in a manner such that the respective roller axes of rotation 22 and 23 are disposed in nonparallel, nonintersecting relation. Accordingly, as can be realized from a comparison of FIGS. 1 and 3, the emulsion and base surfaces 5 and 6 of the filmstrip 4 can be supported by the idler rollers 14 and 15, for movement therebetween, in either of two different relative orientations. That is to say, successive portions of the film strip 4 will be supported for movement from the idler roller 14 to the idler roller 15 in a first longitudinally twisted sense, as shown in FIG. 1, or in a second longitudinally twisted sense, as shown in FIG. 3.
  • a web cutter blade 24 is mounted on the support plate 10 at a location generally intermediate the idler rollers 14 and 15. This blade 24 is disposed so as to be spaced from a film strip portion 4' which extends in the first longitudinally twisted sense between the idler rollers 14 and 15, as in FIG. 1, and so as to sever a film strip portion 4" which extends between such rollers in the second longitudinally twisted sense, as in FIG. 3. Accordingly, as shown in FIG. 3, the free leading end portion 12 of the film strip 4 will be severed from a remaining length of the film strip when the drive and pressure rollers 17 and 18 pull the film strip, in the second longitudinally twisted sense, from the idler roller 14 to the idler roller 15. However, such severance of the film strip 4 will not occur when the film strip is similarly pulled in the first longitudinally twisted sense.
  • the idler roller 14 is located on a lever arm 25 which, in turn, is pivotably mounted on the support plate 10 by means of a pivot pin 26.
  • a helical tension spring27 interconnecting the supportplate 10 and the lever arm 25, serves to urge such arm (with the idler roller 14) in a clockwise direction, as viewed in FIG. 1, about the pivot pin 26.
  • a stop pin 28, fixed to the support plate 10, is disposed to limit such clockwise urging of the lever arm 25.
  • the idler rollers 13, 14 and 15 are equally spaced apart along the path of film movement between such rollers. Moreover, this path of film movement includes an abrupt change of direction or bend at the idler roller 14.
  • FIGS. 1 and 2 will show that when substantially all but the trailing end portion 8 of the film strip 4 has been withdrawn from the web roll cartridge 1, the continued pulling of the film strip by the drive and pressure rollers 17 and 18 will cause the film strip portion 4' to laterally shift out of the path of film movement between the idler rollers 14 and 15 and, thence, into abutment against the web cutter blade 24. In this way, severance of the film strip 4 at the film strip portion 4 will be effected as shown in FIG. 2.
  • Such shift of the film strip portion 4' out of the film movement path serves to pivot the lever arm 25 through the intermediary of the idler roller 14, in a counterclockwise direction as viewed in FIGS. 1 and 2, since the pulling force which is exerted by the drive and pressure rollers 17 and 18 on the film strip 4 is sufficient to overcome the bias of the spring 27.
  • the spring 27 returns the lever arm 25 to the position shown in FIG. 1, and the drive and pressure rollers 17 and 18 continue to rotate so that substantially all but the trailing end portion 8 of the film strip is advanced (without any interruption) between the drive and pressure rollers.
  • a web handling apparatus adapted for use with web material of a kind (a) which is to be removed from a web holder and (b) which has a trailing end portion anchored to such web holder; the combination comprising:
  • means for defining a web path means for moving successive portions of such Web material along said web path from such web holder and, when substantially all but such trailing end portion of the web material is removed from the web holder, for inducing movement of a particular web portion which closely precedes the trailing web end portion out of said web path;
  • a web handling apparatus adapted for use with web material of a'kind (a) which is to be withdrawn from a web holder and (b) which has a trailing end portion anchored to such web holder, the combination comprising:
  • an idler roller for supporting such web material
