Definitions

  • This invention relates to a method of and a device for embroidering a web of cloth or the like traveling between a cloth supply roller and a cloth take-up roller of an embroidering machine, by means of embroidering needles and an embroidering frame, which needles and frame are adapted for operation in program-controlled working cycles.
  • the embroidering area is considerably smaller than in the large high-capacity embroidering machines and the web of cloth must be fed at shorter intervals.
  • care must be taken that between two subsequent working cycles no undesirable pattern displacement occurs.
  • the vertically cloth stretching means i.e. the cloth supply roller and the cloth take-up roller
  • the horizontally cloth stretching means i.e. the pin racks
  • the vertically and horizontally cloth stretching means are reset, thereby to re-establish the connection to the previously embroidered length of cloth as satisfactorily as possible.
  • a really satisfactory continuation of the pattern with almost invisible connections is to a large extent dependent on the skill of the operators.
  • only lengths of cloth corresponding to the width of the embroidering frame can be stretched in the latter so that the lengths 'of the finished goods are dependent on this size.
  • the embroidering needles remain in the cloth during the feed thereof so that a satisfactory connection to the previously embroidered length of cloth is always ensured.
  • any manual setting or readjustment is intended to be dispensed with so that the cloth can be fed fully automatically and rapidly.
  • the web of cloth is intended to be fed through the embroidering frame in its longitudinal direction, i.e. in the direction of the warp threads, so that any desired lengths of finished goods can be produced.
  • the invention provides a method of and device for embroidering by means ofprogram-controlled embroidering needles a web of cloth or the like having an area thereof stretched in a program-controlled embroidering frame arranged between a cloth supply roller and a cloth take-up roller of an embroidering machine, which comprises the steps of embroidering the area of the web of cloth stretched in said embroidering frame by moving said embroidering frame from the supply end to the take-up end of the web of cloth, leaving the embroidering needles in the web of cloth after completion of the last program of the pattern, stretching the web 'portions outside the embroidering frame, shifting said embroidering frame along the stretched web of cloth from the take-up end to the supply end thereof, slackening the web of cloth and initiating the subsequent working cycle.
  • the embroidering machine For automatically feeding the web of cloth the embroidering machine is stopped with the embroidering needles remaining in the web of cloth at the end of the last program of the pattern after which the area of the web of cloth stretched in the embroidering frame has been embroidered, the stopping of the embroidering machine being brought about by a signal provided by a punched card controlling the movement of the embroidering frame, and the cloth supply roller and the cloth take-up roller then are turned in such a manner that the portions of the web of cloth located outside the embroidering frame are stretched, whereupon a presser foot is actuated to urge the web of cloth against a stitch plate and after withdrawing a lock pawl through the action of a solenoid and releasing the movement of the embroidering frame through the action of a further solenoid, rotation is im parted to a driven roller of the embroidering frame thereby to move the embroidering frame along the stretched portion of the web of cloth until when moving into its opposite end position the embroidering
  • the invention provides a device which comprises an embroidering frame arranged between a cloth supply roller and a cloth take-up roller of an embroidering machine and adapted to hold the web of cloth in the stretched condition required for embroidering, said embroidering frame including a first driven roller and a second driven roller for stretching the web of cloth in the feed direction thereof and means for stretching the web of cloth transversely of the feed direction thereof, the two driven rollers being lockable.
  • a pair of idler rollers is associated with each of the driven rollers to form a set cooperating rollers at either end of the embroidering frame, said two sets of rollers being spaced from each other a distance corresponding to the length of stretching of the web of cloth led around each of the sets of rollers in such a manner that the driven rollers will be urged against the associated pair of idler rollers by the action of the web of cloth when this is being stretched.
  • FIG. 1 is a side elevational view of an embroidering frame and of a web of cloth guided thereon;
  • FIG. 2 is a front elevational view of the embroidering frame looking from left to right at FIG. 1;
  • FIG. 3 is a side elevational view, on an enlarged scale, of a roller locking device
  • FIGS. 4 and 8 show various modifications of means for stretching the web of cloth transversely of its feed direction.
  • FIG. 1 shows an embroidering frame 1 which comprises a first driven roller 4 provided with a friction 'coating and rotatably and swingably mounted in brackets 2 and 2 at one end of the frame and a second driven roller 3 likewise provided with a friction coating and rotatably and swingably mounted in brackets 2 and 2 at the other end of the embroidering frame 1.
  • the driven rollers 3 and 4 are lockable and serve for stretching a web of clock 5 to be embroidered and are urged by the tension of the Web of cloth 5, acting in ,the directions of arrows 42 in FIG.
  • the drive for the first driven roller 4 is derived from an electric motor 9 through the intermediary of a reduction gear 7 and a flexible shaft 8.
  • the second driven roller 3 is positively coupled to the first driven roller 4 through the intermediary of a roller chainlti led around a sprocket wheel 7,1, secured to the first driven roller 4, and a sprocket wheel 12, rotatably mounted on the second driven roller 3 and provided with a pressure surface, the sprocket wheel 12 being adapted to be urged by the action of a pressure spring 13 with adjustable force against a friction disc 14 rigidly connected to the second driven roller 3.
  • the sprocket wheel 12, the pressure spring 13 and the frictiondisc 14 are arranged for co-operation in the manher of a slip clutch.
  • the spocket wheel 11 has less teeth than the sprocket wheel 12, so that when the electric motor 9 is switched on the first driven roller 4 will rotate more quickly than the second driven roller 3 until the web of cloth 5 between the two driven rollers 3 and 4- is stretched to an extent determined by the frictional force generated by the slip clutch formed by the sprocket wheel 12, the pressure spring 13 and the friction disc 14.
  • the sprocket wheels 11 and 12 may be of the same size and driven at different speeds. In any event, by providing a pcripheral speed differential between the respective sprockets, i.e., driving sprocket 11 faster than sprocket 12, tension will occur in web 5 controlled by the slip clutch afforded by elements 12, 13 and 14.
  • the slip clutch will out of the teeth of the ratchet wheel 15 when the web of cloth 5 is to be moved in the feed direction designated by arrow 24, i.e. when the driven roller 3 is to rotate in the locking direction of the lock pawl 16.
  • the reduction gear 7 is constructed as a self-locking worm gear and thus adapted to prevent the first driven roller 4 from the turning back and, likewise, the stretched web of fabric 5 from slackening. If the reduction gear 7 used is not of the self-locking type, the driven roller 4 can be prevented from turning back by inserting a conventional one-way clutch, such as shown in Patent 2,051,385, thereby preventing counter-rotation of roller 4.
  • FIGS. 2 and 4 show means for stretching the cloth transversely of the feed direction 24 of the web of cloth 5.
  • the intensity of the stretching in transverse direction can be considerably less than that in the feed direction of the web of cloth 5.
  • These means are embodied in small pin rollers 22 mounted on bars 19 and 20 secured to the embroidering frame 1.
  • the pin rollers 22 are mounted for free rotation on axles extending at an angle 21 to the transverse direction of the web of cloth 5.
  • the border zones 23 of the web of cloth 5 are pulled outwards laterally by the pin rollers 22 when the web of cloth 5 is advanced in the feed direction indicated by the arrow 24, as shown in FIG. 4.
  • the length of the web of cloth 5 between the driven rollers 3 and 4 of the embroidering frame 1 and the bars 1) and 2t fitted with the small pin rollers 22 will be stretched in the feed direction 24- and in the transverse direction while the web of cloth 5 is being fed from the supply roller 25 and wound onto the take-up roller 26.
  • FIGS. 5, 6, 7 and 8 show different means for stretching the cloth in the transverse direction.
  • These means consist of small pin wheels or discs 27 rotatably mounted on angular bars 45) and 41 secured to the embroidering frame ll.
  • By arranging the small pin wheels 27 at an angle 28 (FIG. 7) as well as at an angle 29 (FIG. 8) it is ensured that the individual web lengths will be reliably engaged, stretched and released by the pin wheels 27.
  • By the angle 28 it is ensured that the web of cloth engages the pins on the wheels 27 where indicated by arrows 3% (FIG. 6) and comes off the pins at, or as short a distance as possible behind, the points indicated by arrows 31.
  • the amount of stretching at the outer sides of the web determines the tension of the web in the transverse direction, one half of this amount being indicated in FIG. 6 by the reference numeral 32.
  • the angle 29 ensures that the pins after having left the web of cloth 5 at the points shown by the arrows 31 do not contact the web until they regain the points shown by the arrows 30', with the pin wheels 27 moving in the direction of rotation 33 determined by the feed direction of the web indicated by the arrow 24.
  • a warp thread 34 of the Web of cloth 5 is shown in FIG. 6 in relatively heavy lines and in each of FIGS. 1, 7 and 8 a shuttle 35 and an embroidering needle 36 are represented for reference.
  • the vertical frame adjustment as shown diagrammatically in FIGURE 1, may be accomplished by a chain or belt which has sections 48, these sections having outer ends attached to the frame 1 and inner ends attached to a rack, these sections extending over the rollers 47.
  • An electric motor 46 drives a pinion which engages and moves the rack, and thus the frame.
  • a so-called special function out is punched in at the end of the program, which function, however, is only connected through to the disconnecting contactor for the main motor when a limit switch is simultaneously closed.
  • This limit switch can beset so that it acts only in the zone of the last program with which the embroidering area of the web of cloth 5 stretched in the frame 1 can be embroidered, i.e., only when the embroidering area of cloth 5 within the frame 1 is completely embroidered and the frame 1 has moved into its end position shown in FIG. 1.
  • the special function out stops the device when the embroidering needles 36 are in the cloth.
  • a limit switch is operated to switch off the electric motor 9 and switch on a time relay working with a delay great enough to permit the electric motor 9 to come to a standstill before transmitting the impulse received.
  • This impulse is transmitted to the cut-off relay for the solenoid 18 and the solenoid which has effected the release of the vertical movement of the embroidering frame 1.
  • the second driven roller 3 and the embroidering frame 1 are fixed again.
  • the return travel of the presser foot 37 is initiated and simultaneously the cloth supply roller 25 and the cloth take-up roller 26 are unlocked so that the lengths of the web of cloth 5 which are located between the second driven roller 3 and the cloth supply roller 25 and between the first driven roller 4 and the cloth take-up roller 26 are slackened and the embroidering frame 1 can easily be moved during the embroidering process following thereafter.
  • a method of automatically feeding a length of cloth tensioned inan embroidering frame to permit continuous embroidering of a pattern repeat comprising the steps of:
  • a device for automatically feeding a web of cloth or the like in an embroidering machine having a cloth supply roller, a cloth take-up roller, and needle means extending transversely of said web comprising a movable embroidering frame located between said supply and take-up rollers, said frame having mounted thereon a first driven web engaging roller and a second driven web engaging roller at opposite ends of the frame in the feed direction, means driving said rollers to rotate the peripheries thereof at relatively different velocities for moving said frame longitudinally along the web toward the supply roller while placing the web between said rollers under tension'in the feed direction, said two driven rollers having means for retaining said rollers in fixed position against rotation, and means on said frame for stretching said web of cloth transversely of the feed direction thereof.
  • each of said driven rollers is movable transversely of its axis of rotation and wherein a pair of idler rollers is positioned adjacent each of said driven rollers, each of said pair of idler rollers having fixed axes of rotation spaced apart a distance corresponding to the amount of stretching in the web of cloth, whereby each of the driven rollers will be urged against its associated adjacent pair of idler rollers by the action of said web of cloth when it is being tensioned.
  • means including a speed change drive operatively connects said driven rollers, said driven roller on said cloth supply end of said frame being rotated at a slower relative speed than said driven roller on said cloth take-up end of said frame, whereby the web of cloth will be tensioned in its feed direction.
  • said means for stretching said web of cloth transversely of said feed direction includes planar pressure surfaces mounted on said frame on opposite sides of said web of cloth, said surfaces being in engagement with one face of. said web at the longitudinal edgesthereof, and pin rollers rotatably mounted on said frame adjacent said planar pressures surfaces and engaging said web of cloth on the opposite face thereof, the edges of said cloth passing between said pin rollers and said pressure surfaces and being gripped thereby.
  • each of said pin rollers is substantially parallel to the plane of said web of cloth and is angled forwardly in the feed direction of said Web of cloth.
  • said means for stretching said web of cloth transversely of said feed direction includes planar pressure surfaces mounted on said frame on opposite sides of said web of cloth, said surfaces being in engagement with one face of said web at the longitudinal edges thereof, and rotatable discs mounted on said frame adjacent said pressure surfaces, each of said discs having pins on the radial face thereof engaging said web of cloth on the opposite face from said pressure surfaces, the edges of said cloth passing between said discs and said pressure surfaces and being gripped thereby.
