Definitions
- ABSTRACT The device includes a displaceable workpiece clamp on a two-needle sewing machine which is pivotable about a pivot axis coinciding with the'axis of symmetry of the needles into selected angular positions defined by the displacement direction of the clamp and the longitudinal axis of the sewing machine arm shaft, the sewing machine being lockable in adjusted positions.
- a guide mechanism is provided for folding a braid strip, and a cutting knife is provided to make a longitudinal slit and works between the two needles, the cutting knife being driven by a drive member included in the sewing machine.
- a set of individually controllable angle knives are provided for making diverging incisions at the ends of the longitudinal slit.
- the angle knives are mounted separately from the sewing machine for conjoint rotation about respective axes each of which is parallel to the motion path of the associated angle knife, and a crank and link arrangement connects the angle knives to the sewing machine for positive angular adjustment responsive to pivoting of the sewing machine.
- a support for the cutting knife is mounted separately from the sewing machine and is slidable on fixed guides.
- the mounting for the cutting knife support is formed with an elongated slot having generally a figure eight configuration, and the cutting knife drive member extends through this slot and is coupled to the cutting knife support, the arrangement providing for relative movement between the cutting knife support and its drive member.
- the present invention relates to a device for making braid openings extending straightly or obliquely to the hem edge of cutout pieces of garments.
- the necessary offsetting of the ends of both seams in case of a changed oblique position of the braid opening relative to the hem edge of the cutout piece, while maintaining the equal length of the seams, is obtained by a corresponding control of the individually engageable and disengageable needle bars of the sewing machine.
- the wedge-shaped cutting blades of the angle knives are mounted in sets of two on respective knife spikes, for pivotal motion about horizontal hinge pins provided near the tips of the spikes. At its free end, each cutting blade is formed with a control arm.
- the control arms engage into corresponding recesses of triangular swinging arms which are pivotable about the vertical longitudinal axis of the spikes by means of doublemotion control levers, in accordance with a pre selected oblique position of the braid openings.
- the individual cutting blades are swung, by the control arms which are laterally spaced from the respective axis of rotation of the triangular swinging arms, in mutually opposite directions about their hinge pins fixed near the spike tips so that, in conformity with the oblique position of the braid opening, the two cuts of the angle incision become unequal in length while the depth of penetration of the knife spikes into the workpiece is always the same.
- the invention is directed to the problem of reducing the costs incurred in the manufacture of complicated devices for making straight and oblique braid openings, and of providing an arrangement permitting, within certain limits, to make braid openings extending at any desired angle to the hem edge of the workpiece.
- the problem solved by the invention is to appropriately arrange the angle knives and the central knife, and to provide drive connections, between the sewing machine and the angle knives as well as between the sewing machine and the central knife, such that, when the sewing machine is swung into any angular position relative to the advance direction, the angle knives are automatically brought into a corresponding position while the cutting knife mounted in the center remains in its position aligned with the advance direction, irrespective of the angular adjustment of the sewing machine.
- this problem is solved in that the angle knives are mounted independently of the sewing machine for conjoint pivotal movement about respective axes parallel to their respective paths of motion, and connected to the sewing machine through transmission means effecting positive adjustment of the knives corresponding to the angular adjustment of the sewing machine, and that a support for the cutting knife is mounted separately of the sewing machine for sliding on fixed guide means and is connected to its drive mechanism by coupling means permitting a relative motion between the support of the cutting knife and its drive mechanism.
- An object of the invention is to provide an improved device for making braid openings in cutout pieces of garments.
- Another object of the invention is to provide such a device in which the cost of manufacture is greatly reduced.
- a further object of the invention is to provide such a device including an arrangement permitting the making of braid openings extending at any desired angle to the hem edge of the work piece.

- Each blade 58, 59 is engaged, by its forward narrow forked end, into a slot 62, which is provided on the tip of the respectivespike-like portion 54, 55, and which is open at its side opposite tothe working direction of the knife.
- Each blade 58, 59 is fixed against position changes so that its narrow forked end engages over a cross pin 63 projecting from tip of the respective spike-like portion 54, 55 and its wide end is secured to the latter by means of a screw 64 (FIG. 1).
- each knife carrier 56, 57, with the respective angle knife 52, 53 mounted thereon, is actuated by a respective pneumatic cylinder 65, 66. Electromagnets might also be used for the same purpose.
- the carrier 56 of angle knife 52 is fixed to the upper end of the piston rod 67 of pneumatic cylinder 65
- the carrier 57 of angle knife 53 is fixed to the upper end of the piston rod 68 of pneumatic cylinder 66.
- the top ends of pneumatic cylinders 65, 66 are secured to the horizontal leg of a supporting angle 69 mounted on frame 2.
- Piston rods 67 and 68 extend upwardly through the horizontal legs of angle 69 and are freely movable therein.
- Two guide members 70, 71 having a rectangular C-section and legs of unequal length, are mounted so that their legs embrace the horizontal leg of supporting angle 69 and rotatably receive piston rods 67, 68 extending therethrough.
- Respective guide rods 72, 73 for knife carriers 56, 57 are passed through corresponding bores in guide members 70, 71 and secured thereto, for example, by brazing, pinning, or screwing.
- Each knife carrier 56, 57 is formed with a respective forked end portion 74, 75 in which the associated guide rods 72, 73 are received. This arrangement permits a straight line guidance and conjoint angular adjustment of knife carriers 56, 57, along with angle knives 52, 53 about piston rods 67, 68 of pneumatic cylinders 65, 66.
- guide rods 72, 73 are connected to each other by means of a link 76.
- a push bar 77 connects guide rod 72 to the stud 78 of a crank 79.
- Crank 79 is rigidly fixed to pivot pin 5 mounted in base casing 6 of sewing machine 7, so that it follows the pivotal movement of sewing machine 7 about pivot pin 5.
- An opening 80 is provided in bed plate permitting angle knives 52, 53 to pass therethrough, the width of the opening being dimensioned so that, in any adjustable orientation of sewing machine 7, angle knives 52, 53 are unimpeded in their upward working motion.
- Sewing machine 7 is adjustable to any angular posi tion between the end positions designated R and L.
- a clamping mechanism is provided comprising a clamp rail 81, secured to the base casing and engaging table plate 1 from below, and a threaded bolt 83 extending through an arcuate slot 82 in table plate 1 and screwed into clamp rail 81.
- Bolt 83 is made in one piece with a handle 84.
- the inventive device operates in the following manner.
- a cutout piece W (FIGS. 5 and 7), which has been provided with markings for slit 32 of a braid opening and for the angle incisions at the ends of slit 32, is placed on table plate 1 and bed plate 20 in accordance with optical markings, so that the advance direction V of workpiece clamp 21 corresponds to the marking for slit 32 and, consequently, cutting knife 33 for making the slit is aligned with the marking and cutout piece W occupies a definite initial position relative to needles 12.
- Braid strip P having a predetermined length and folded into an inverted T form by guide mechanism 50, is fed below the pressure feet and needles 12, so that cutting knife 33 is positioned between the two raised borders of braid strip P.
- the pressure feet 9 are then lowered on braid strip P at both sides of the raised borders thereof, and workpiece clamp 21 is brought above the aligned cutout piece W and lowered on the same by means of hand lever 26.
- Tension spring 29 holds work-- piece clamp 21 down and presses cutout piece W firmly against bed plate 20 so that any unintentional displacement of cutout piece W is prevented and the advance of workpiece clamp 21, along with cutout piece W, is made possible.
- sewing machine 7 and advance unit 23 are started. While sewing machine 7 is running, the movement of workpiece clamp 21 is controlled, preferably step-by-step in synchronism with the stitch'formation, by supplying pressure fluid through the connections of the double-acting working cylinders of advance unit 23 so that, initially, the two threads are locked at the starting end of seams 13 by condensing the stitches or by a temporary reversal of the advance direction and then the two seams 13 are sewn.
- a programmed control of the individual mechanisms of the device can be effected in various ways, for example with the aid of fixed switches arranged in rows and actuated by corresponding rows of trip cams which may be provided on a supporting plate secured to workpiece clamp 21.
- a selector switch may be provided, by means of which the different switches or rows of trip cams are preparatorily selected, for example for making braid openings of unequal lengths.
- Another possibility is to use a control cylinder carrying carns for actuating the corresponding switches and connected to the drive of the sewing machine. Particularities of an electric control may be dispensed with, since such a control is wellknown and does not constitute an object of the present invention.
- cutting knife 33 is engaged. In operation, cutting knife 33 is projected into slot 35 of throat plate 36 and, during the sewing, cuts central slit 32 extending between the two seams 13 and also the layer of folded braid strip P reposing directly on cutout piece W.
- the first angle knife 52 is actuated at the respective point by admitting compressed air into the pneumatic cylinder 65, so that angle knife 52, whose carrier 56 is fixed to piston rod 67 of pneumatic cylinder 65, moves through opening in bed plate 20 upwardly and, during this motion, forms the first angle cut 51 in cutout piece W and the layer of folded braid strip P reposing immediately thereon.
- the finished angle cuts extend from the ends of slit 32 in a V-form up to the ends of the parallel seams 13.
- Angie knife 52 may be returned into its initial position either by means of a return spring or by admitting compressed air through a second connection.
- Cutting knife 33 is disengaged at the point provided for the second angle cut, the seams are finished up to the predetermined length and locked, the threads are cut during the last upward motion of needle bar 10, the pressure feet 9 are lifted, and sewing machine 7 is stopped.
- clamping mechanism 81-84 For making a braid opening extending obliquely to the hem edge of a cutout piece, as shown in FIG. 6, where the sequence of operations is the same as in the case of straight braid openings, clamping mechanism 81-84, locking the sewing machine in its middle position M (FIG. 2), is disengaged and sewing machine 7 is pivoted about an axis coinciding with the longitudinal axis of pivot pin 5 and the longitudinal axis of the needle-bar into a position indicated by the line L (FIG. 2),
- sewing machine 7 is locked in the frame by means of clamping mechanism 8l84. If desired, sewing machine 7 may. be locked in any position within the pivotal zone limited by lines R and L. To facilitate the exact positioning, table plate 1 may be provided withappropriate markings adjacent arcuate slot 82, as indicated in FIG. 2.
- kidney-shaped opening 44 through which knife-driving rod 34 extends, makes possible a relative movement between the latter, which is mounted for up-and-down motion in the head of the sewing machine-and laterally spaced from needle bar forming the axis of. rotation of the machine, and, consequently, pivoted along with the machine, and support 37 of cutting knife 33, which is slidable on fixed guide rods 42, 43.
- the center offset between support 37 and knife-driving rod 34, produced by the pivoting of sewing machine 7 about pivot pin 5, is thereby compensated.
- cutting knife 33 Due to this and to the mounting of support 37 of cutting knife 33 on fixed guide rods 42, 43 separated from the sewing machine, cutting knife 33 keeps its constant alignment with the advance direction while maintaining the coupling connection between support 37 and knifedriving rod 34 so that, even in non-central positions of the sewing machine, slit 32 is cut in a smooth and neatv manner.
- guide rods 72, 73 are connected to each other by link 76 and that the forked end portions 74, 75 embrace guide rods 72, 73.
- Knife support 37 is designed so that the center offset between knife driving rod 34 and support 37, produced by the pivotal movement of sewing machine 7,. is compensated. Also, angle knives 52, 53 adapt themselves automatically to any oblique position of sewing machine 7 relative to the advance direction.
- the device can be used for making straight as well as oblique braid openings. The changeover to the respective desired oblique position can be effected without any difficulty. Therefore, it is irrelevant in which sequential order the straight and oblique braid openings are made on lefthand and righthand cutout pieces of garments such as, for example, jackets. For controlling the machine in all provided positions, a single basic program, needed in any case for making a braid opening, is sufficient.
- the device can be used for making braid openings of different lengths.
- workpiece clamp 21 can be equipped with a holder for a pocket flap for making braid pocket openings with flaps.
- a device for making braid openings extending either straightly or obliquely to the hem edge of cutout pieces of a garment, of the type including adisplaceable workpiece clamp, on a two-needle sewing machine which is pivotable about a pivot axis, coinciding with the axis of symmetry of the needles, into selected angular positions, defined by the displacement direction of the workpiece clamp and the longitudinal axis of the sewing machine arm shaft, and lockable in these positions, a folding guide mechanism for a braid strip, a cutting knife, for making a longitudinal slit, working between the needles, a drive memberfor the cutting knife included in the sewing machine, and a cutting mechanism, including a set of individually controllable angle knives, for making diverging incisions at the ends of the longitudinal slit: the improvement comprising, in combination, means mounting said angle knives separately from said sewing machine for conjoint rotation about respective axes each of whichis parallel to the motion path of the associated angle knife; transmission means connecting said angle knives to said sewing machine
