  • a web feeding mechanism for photographic copying apparatus in which a supply roll of the web is at least partially, and optionally entirely, surrounded by a coaxial arcuately curved supporting surface having its leading edge terminating adjacent a pair of feed rollers, which rollers are capable of independent rotation about their own axes and of bodily translation about the web roll axis with said arcuate supporting surface, a mechanical drive being operative during the bodily translating movement of the feed rollers to rotate the same about their axes to positively withdraw a length of the web material from the web roll which length is received on the arcuate supporting surface.
  • the mechanism includes a cutting device for severing the web length thus produced from the remainder of the web adjacent the feed rollers.
  • the feed rollers and the supporting surface can be arranged to rotate in a circular path around the web roll with the feed roll drive being operative through only a portion of that path allowing an opportunity for electrostatic charging and exposure of the length of Web material to an image of the original to be copied while the web material is supported on the arcuate surface as such surface is translated through a further portion or portions of the circular path.
  • the feed rate of the original to be copied through an exposure system can be synchronized with the rate of linear travel of the web length on the supporting surface so that an optical image of the original can be projected onto the web length while both the original and that length are moving in synchronlsm.
  • This invention relates to apparatus for separating rolled material into pieces of material of a required length or lengths.
  • the invention can be usefully applied in the packaging industry and'in the document copying field. (These are only examples of the potential uses of the invention.)
  • Constructions of apparatus capable of continuously separating rolled material into shorter pieces have already been proposed but for one reason or another these constructions are not appropriate for apparatus to be embodied in or used in conjunction with photographic or other document copying apparatus. It is an object of the invention to provide a construction of apparatus which is suitable for application in this way as well as in other ways.
  • Apparatus comprises means for rotatably supporting a said roll about its axis, rollers which are bodily rotatable about such axis and which grip between them during such bodily rotation the free end of the material of the roll, means for rotating such rollers about their axes during their said bodily rotation thereby to cause material to be drawn from the roll, and cutting means operative after each of successive intervals of time during such rotations of the rollers so as each time to cut the material along a transverse line at a position between its then free outer end and the position at which the material is gripped by such rollers.
  • the rolled material remains gripped by the rollers at or near its free end, throughout the operation of separating the material into separate lengths.
  • the cutting is performed at one or more fixed cutting stations past which the successive portions of material drawn off from the roll by the rollers are drawn in the course of the rotation of the said roll and rollers.
  • the cutting is performed while the portion of the material to be cut oif is folded back so that the free end of the material is trailing the transverse zoneat which the cut is to be made.
  • the cutting means then operates at a position such that it cannot impede the ongoing rotating motion of the rollers with the gripped fresh end of the rolled material and the necessity of this unimpeded motion does not place restriction on the design of the cutting mechanism and its operation or the design of guide means for guiding the severed length of material to a delivery point.
  • the successive portions of the rolled mate rial drawn off from the roll by the rollers are caused to fold back over a curved surface which is substantially concentric with the roll of material and rotates bodily therewith, and in the most preferred embodiments of the invention such curved surface is provided by a drum within which the material roll is mounted and which is provided with an exit slot, parallel with the drum axis, through which the rolled material is drawn by the rollers, these latter being located in the immediate vicinity of such, slot.
  • the material emerging from the slot may be caused to lie flat against the outer surface of the drum, at least just prior to the severance of such portion from the roll, by one or more outer rollers co-operating with the drum surface and/ or by a fixed curved guide or guides spaced from the drum surface and substantially concentric therewith.
  • a very high capacity apparatus can be realised by causing material withdrawn from the roll to be folded back over a drum enclosing the roll and by providing cutting stations at successive positions around the periphery of the drum for cutting two or more separate sheets from the roll during each rotation thereof.
