Definitions

  • This'invention comprises improvements in or relating to means for cutting fabrics into lengths or portions.
  • This is a division of application Serial Number 173,017, filed March 5, 1927.
  • V The invention has particular, thoughnot exclusive, reference to fabriowhich is produced in a continuous piece and subsequently out intothe requisite lengths to form towels, cleaning clothsand other like articles.
  • In the manufacture of fabric forproducing such articles it is customary at predetermined intervals "to discontinue for a certain specified time the lay or feed of the yarn which extendstransversely across the longitudinally extending threads and binds to- 'gether such threads, thus producing lengths of fabric connected at intervals by comparatively j narrow.
  • tra isv'eise bands composed solely? of longitudinally extending threads. This, in fabric'composed of warp and weft, produces Weftless bands between predetermined lengths of complete or solid? fabric, and for convenience these bandswill hereinafter be referred to "as weftless divisions; i
  • Affeature of the present invention consists in the, pro'vision'of a machine for cut ting fabrics into lengths or portions com-' prising a rotary fabric feed ng. frame, a'
  • Another feature resides in the provision of an intermittently rotatable fabric feeding frame hpvi'ng elements thereon which 7 serve thedu'al purpose of intermittentlywithdrawing a predetermined length of fabric from the'supply and anchoring the fabric in position for being acted upon by the cutter.
  • j V 1 7 Further features reside in the provision of means for alternately movingthe cutter into] and' out of cutting. positioii,ancl means for'en'ablingthe length or quantityof fabric withdrawn andseverecl at each operation to be variably adjustedas required;
  • Figure 2 is an elevation'al view of part'of the machine shownin Figure 1 looking at y
  • Figure 8 is a planview showing the cutte'rs used on the machine.
  • Figure 5 is a side! elevational view showing a further modified construction.
  • the fabric rollers 1 (four of which are to rotate within brackets or bearings 2 ad- V, In the one method of carrying out the 'in '80 illustrated) are mounted one above the other j'ustably or otherwise'carried at. the rear l part of the machine frame 8,1 the'brackets at either or both ends of thetrollers preferably being hinged or formed with a hinged or displa'ceable portion for facilitating 1 the withdrawal of anemptyroller 'or'beam and the insertion ofla fresh roller.

  • the fabric 8 isguided to the rotating frame and the separate lengths of said fabric maintained out of contact with each other prior to reaching the frame 1 by suitably disposed and adjustably i'uounted rollers or the like 10.
  • frame +1 may be effected from disc crank or eccentric 11 carried by shaft 12 driven fronil any convenient source of power, said crank carrying a pivoted pawl 13 projecting upwardly therofron'rand held in engagement. by a suitable spring 14 with a ratchet wheel 15 keyed on t 1e central spindle 1(3 of f 'ume l the number of teeth on the ratchet coinciding with, and being angularly spaced to the same extent as the arms 4:.
  • a suitable stop 17 limitstheilateral movement of the pawl 13 under the influence ofits spring.
  • a plurality of rotary cutting discs 18 are rotatably mounted upon separate laterally aligned ares, said discs being arranged to overlap each other to a suitable extent.
  • These cutters are mounted upon a suitable plate or frame 19 which is slidahly adjustable within or upon another plate or frame 20 in a direction at right angles to the axis of the rotary frame at. the adjustment being effected by any suitable means such as a screw memher 21.
  • the plate or frame member 20 is also slidable to and fro within suitable guides 22 carried by or forming part of the machine frame 2 ⁇ , this reciprocative sliding movement of the frame 20 being required in order to move the cutters 18 alternatively into and out of engagement with the fabric 8, the cutters being brought into engagement with the fab- .ric when the frame 4t stationary and moved away from said fabric after the cutting operation and before the frame a commences to rotate to bring further fabric into position for cutting.
  • This reciprocative movement of the frame 20 with cutters 18 may be effected from the shaft 12 through the intermediary of a second disc crank carried by this shaft, a horizontally extending rod or link 2%, an upwardly extending centrally pivoted lever 25 pivotally connected at itslower end to rod 21 and at its upper end by pin and slotpcon' nection to the sliding frame 20.
  • the operation is so timed that while the pawl 13 is rotating the frame 1 the frame 20 is away from the fabric and. while said pawl 13 is being brought down and the frame f is maintained stationary, the frame 20 is moved towards the fabric so as to enable the cutters to sever same.
  • Simultaneous rotating of the cutting discs may be effected in any desired manner such,
  • n-es-edpin 81 (I igures 2 and 5) .may be provided adapted to engage withone of a series of peripheral notches 32 in wheel 33 thearm'being sufiicient to move the cutter throughthe fabric" and clear of same' ateach stroke, 'this movement being; timed so that while/the frame 4 is being rotated the arm35 isstationary, and whilethe frame-4 is sta- V e p I ternally screw threaded'holes ineach transtionaryith'e,cuttingstroke is effected.
  • arm-as has pivotally-connect-ed thereto at a.
  • The' arrangement is such that as the shaft 42 with half cog 41 rotates, the latter transmits during one half of its revolution rotary motion to the gear wheel and the disc crank rotating therewith, during which movement the cutter arm 35 is, through the medium of the connecting rod .37, angularly displaced to traverse the cutter across the machine.
  • the second half of the revolution of the half cog 41 which coincides with the rotative movement of the frame'4-no motion is transmitted to the cutter arm by reason of'there being no intermeshing engagement between the half wheel 40.
