Definitions

  • ABSTRACT An electro-pneumatically controlled mechanism is provided, for instance for use with a sewing machine having a rectilinear feed means, to enable the curved and/or straight marginal portions of flexible sheet-like material to be automatically fed and processed continuously through the operating zone of a tool (such as a needle) of the machine.
  • a work supporting table has an at least partly arcuate periphery over which the work may be draped.
  • a corner sensing means actuates a mechanism for gripping a portion of the work at the proper time and swinging it approximately about a turning center thereby progressively positioning the work relative to the tool.
  • a rectangular work piece thus progressively has its successive comers trimmed to a predetermined radius and sewn.
  • a second sensor counts the successive comers turned in order to automatically stop operations when all or a desired portion of a periphery has been processed.
  • a third sensor automatically serves to check pressure of the engagement of a work edge with the edge gage to prevent unwanted buckling or folding of the work edge.
  • a further object is to provide an easily operable overedging machine capable of continuously and automatically processing. straight edges and interconnecting curved portions of wipe towels, face cloths, and the like.
  • auxiliary control system of electropneumatic type for enabling a sewing machine to stitch the whole or a selected portion of a work margin including corners of predetermined curvature, an operator or other device merely presenting each work piece initially.
  • an illustrative overedge sewing machine of suitable character is fixedly mounted with its throat plate substantially horizontal and overlying conventional feed dog means.
  • the throat plate defines a needle operating zone relatively to which work pieces are to be progressively guided.
  • a novel and substantially flat work supporting table even with the throat plate and usually of less width than the work which may overhang, has a convexly arcuate edge disposed ahead of the needle operating zone and extending toward but spaced from an edge gage to aid edge guidance as hereinafter explained.
  • an edge folding device immediately ahead of the stitch forming means is an edge folding device, and still further ahead is an edge gage for guiding the edge of the work to the folder.
  • a plurality of sensors adjacent to the latter and preferably fluidic are thereby actuated to control the operating cycle.
  • air flow switching of a corner turning sensor signals for operation of a turning arm to swing the work as the rectilinear work feeding means continues to operate, bodily about a center spaced from the needle axis.
  • Another sensor counts the number of corners so turned in order to actuate accessory devices such as a thread cutter, and to elevate a work spreading plate from the work table to provide passageway for a final overlapping seam portion before terminating a cycle of operation.
  • a third sensor controls air flow directed against a side of the work piece to stabilize and yieldingly limit the pressure with which an edge of the flexible work shall bear against the edge gage.
  • each of the fluidic sensors may be provided with graded orifices, the larger pairs of orifices being closer to the edge gage, whereby appropriate functioning is attained on work pieces of different mesh or porosity.
  • FIG. 1 is a perspective view, from the front, of work guidance means and accessories as provided for an overedging machine indicated by dash-lines in the background;
  • FIG. 2 is an end view, largely in vertical section, showing a work spreader plate, work guidance means, and other instrumentalities as seen in their inoperative or up positions relative to a work supporting table;
  • FIG. 3 is a view corresponding to FIG. 2 but illustrating the several parts lowered into operative work-engaging relation;
  • FIG. 4 is a section taken on the line IV-IV of FIG. 3 showing work guidance elements in relation to different positions of the work;
  • FIG. 5 is a view somewhat similar to FIG. 4 but showing stitching operation following corner trimming and counting;
  • FIG. 6 is a schematic diagram of a fluidic control circuit which may be employed.
  • a machine 10 for instance an overedging machine such as a commercially available Merrow model M3DR, is fixedly mounted with its throat plate 12 (FIGS. 1 4 and 5) disposed at a convenient horizontal position.
  • the plate overlies rectilinear feeding feed dog mechanism 13 (not shown except in FIG. 5) for incrementally advancing a work piece W to the left as seen in FIGS. 4 and 5 and parallel to a straight stop cover 14.
  • the plate 12 defines a needle operating zone It is to be noted that other forces are also simultaneously tending to aid in restoring the work edge to be overedged into contact with the gage 24.
  • the feed dog repeatedly exerts feeding movements tending also to swing the work counterclockwise, a portion of the work overhangs the convex outer edge 22 of the table 20 and tends to slide circumferentially thereby shifting the horizontally supported portion of the work toward the edge gage independently of any urging of the swing finger tip 72.
  • the width of the table 20 should be appropriate for the nature of the work and not provide excessive drag tending to misalign the work with the gage 24.
  • the sensors 60, 62 are provided for counting the desired number of comers, i.e. occasions when edge curvature of the work is sufficient to require work swinging by means of the finger 70 in response to noninterruption of the sensors 56, 58.
  • the control circuitry responsive to the sensors 60, 62 counting the four corners will stop the machine and, in this case, automatically actuates a chain stitch cutter 102 (FIGS. 1-4) controlled by fluid pressure admitted to a cylinder 104.
  • This cylinder is supported from a bracket 106 depending from the plate 26 and has a piston rod 108 operatively connected to the cutter 104.
  • the corner counting circuitry may be adjusted to actuate the cutter and stop the machine at any selected number of corners turned.
  • the sensors 60, 62 also serve another important purpose. When the last corner has been overedged, they act automatically to exhaust the cylinder 50 thereby allowing the spreader plate 30 to be spring-lifted sufficiently to enable the additional thickness of the seam of the initial overedging to pass thereunder. The full perimeter of the work piece W may then be processed and the overedging overlapped adjacent to the final corner as desired. Also, the present comer count being completed, the turning tip 72 remains down engaging the workpiece as the finger 70 is rotatively retracted to move the material about to engage the trimming knife and presser foot away from the sewing area.
  • the sensors, 64, 66 are disposed to prevent such misalignment and operate as will next be described.
  • the sensors 64, 66 are disposed immediately adjacent to the edge gage 24 in position to be interrupted just prior to work edge crowding of the gage.
  • a sequence of principle operations of the machine will now be briefly described having reference in part to FIG. 6.
  • a rectangular work towel W for instance, is inserted on the table 20 under the plate 30 and with a starting portion of a first straight side in the needle operating zone Z.
  • a presser foot 112 (FIG. 1) of the machine 10 and the spreader plate 30 are then lowered either manually or, in the illustrative machine, automatically following closure of a starting switch 114 (FIG. 6).
  • Presentation of the work W with its straight trailing edge in contact (or near contact) with the gage 24 interrupts the fluidic sensors 56, 58 and 60, 62.
  • the arrangement in the control and counting circuit shown preferably is such that Schmitt triggers 3-9 and 2-8 respectively associated therewith have their bias pressure so adjusted that they switch on when two air jets are interrupted by the work and switch off when only one is thus interrupted. A single thread or small opening between threads of the work. will not trigger the switches.
  • the work presentation also interrupts the sensor 64, 66 shifting its Schmitt trigger l-7 and causing signals to be applied to valves V-7 and V-9.
  • the valve V-7 supplies air flow to the nozzle of the antiedge folding means above described.
  • Signals are applied to fluidic devices 4-10, 5-11 and 6-12 properly to shift each counter stage, and to a valve V4 to supply air pressure to switch PS-l, to valve V-3 which lowers the presser foot 112, and to a clutch (not shown) controlling drive of the motor 10 and operated by a piston cylinder device 116 (FIG. 6).
  • the actuation of the switch PS-l is effective to draw suction via the duct 18.
  • valve V-1 is shifted to pressurize the cylinder 50 and lower the plate 30.
  • a signal is sent to valve V-6 pressurizing cylinder 98 to lower the finger tip 72 into work engagement at the position shown in FIG. 1, and a signal is sent to a valve V-S pressurizing the cylinder 82 to cause the finger 70 to rotate counterclockwise thereby turning the work piece W so that a corner C is overedged and registering the first comer in the counting means.
  • the earlier mentioned steps are now repeated for further rectilinear overedging.
  • the machine 10 at no time necessarily slows or stops as the corner is formed and sewn. As the next straight edge portion of the work piece interrupts the sensors 56, 58 and 60, 62 and contacts the edge gage 24 the signal is removed from the valves V-5, V-6, respectively, and the turning tip 72 is lifted from the work and returned angularly to its starting position in readiness for the next work comer. The machine does not stop but continues sewing the next straight edge.
  • a signal from the fluidic device 18 causes the valve V-l to shift and exhausts the cylinder 50 thus allowing raising of the spreader plate 30 by the return spring of that cylinder and accommodating the thicker previously rolled and sewn work edge.
  • the corner tuming mechanism operates as previously described, and the fluidic device 13-19 (FIG. 6) signals devices 15, 16 and 21 (a time delay determining how much longer the machine is to operate) whereby the valve V-S is shifted causing the turning tip 72, while still engaging the work, to return clockwise from its dashed to solid line positions shown in FIG. 4.
  • a signal to PV-l initiated by the time delay associated with fluidic device 20 (FIG. 6), causes the valve V-2 to effect one operating cycle of the cutter 102 to sever the thread chain automatically and allow removal of the work from the machine.
  • Actuation of a valve V-8 (FIG. 6) will cycle the thread cutter 102 when desired, and actuation of a valve V-10 is effective to operate the sewing machine 10 without benefit of its work guidance system.
  • a machine for progressively operating on the margin of a flexible work piece having curved and/or straight peripheral portions comprising an operating tool, a work support, an edge gage on the support ahead of the tool, feed means for rectilinearly moving the work piece on the support past the gage and to and through the operating zone to the tool, work guidance mechanism responsive to the position of an edge of the work ahead of the tool for urging the work edge toward progressive contact with the gage, and a work spreader plate movable toward and from parallel operative relation to the work support to aid said guidance mechanism in progressively presenting the work edge to the tool with the work outspread.
  • an overedging machine having stitch forming instrumentalities including a needle and a folder, a flat bed for slidably supporting a flexible work piece to be overedged, rectilinear feed mechanism adjacent to the needle, means including an edge gage ahead of the needle for progressively guiding an edge of the work piece to and through the operating zone of the needle and said folder, said guidance mechanism comprising a spreader plate mounted for relative movement heightwise of the bed for accommodating a work piece on the bed substantially in its own plane, a work turning member engageable with the work on the bed, and means automatically operable to rotate said member while engaging one locality of the work to slidably swing the work between the spreader plate and the table and tend to maintain an edge of the work to be overedged progressively in contact with the folder and contact or near contact with said edge gage.
  • said circuit includes a sensing means adjacent to the edge gage for controlling by air flow the pressure of edgewise engagement of the work with said gage.
  • said sensor includes a pair of fluidic elements respectively having graded orifices aligned for communication and interruption by the work edge to provide a range of sensitivity in accommodating work pieces having different degrees of perviousness.
  • a work support having an edge gage positioned thereon ahead of the tool, a work spreading plate smaller than and overlying the work support and movable heightwise thereof to accommodate reception of the work piece therebetween, means operative adjacent to the operating zone of the tool for rectilinearly feeding the margin through said zone, a work turning member cooperative with the work support and movable heightwise thereof, and corner sensing means responsive to relative movement of approach of the work edge with respect to said gage for angularly operating the turning member to urge a comer portion of the work piece to progressively pass response to operation of the corner sensing means a predetermined number of times.
  • control circuit is adapted to maintain said work turning member in work engaging relation after a predetermined number of corners are sensed by said corner sensing means whereby angular return of the member is effective to remove the work piece from said tool and edge gage.
  • a tufted pile fabric and method of making the same in which rows of pile tufts are formed extending upwardly from the upper face of a backing fabric or base and have lower bights at least partially positioned above the plane of the lower face of the backing fabric to permit use of less pile yarn for obtaining any given height of pile; Also, a plurality of stitching threads are positioned along the lower face of the backing fabric and portions of the stitching threads are inserted through the lower bights of the tufts to secure them to the backing fabric.
