Definitions

  • ABSTRACT An edge finishing machine for an opening in a garment, the machine comprising a table movable on a frame by cam means, a sewing machine mounted on a shaft rotatably supported on the table.
  • the cam means and the rotational movement of the sewing machine causing the sewing machine needle to traverse a path which is a duplicate of the profile of the garment opening and a garment support located adjacent the machine.
  • the present invention has been devised primarilyto provide a machine which will edge finish and if desired simultaneously elasticise the leg openings of female briefs.
  • the invention provides an edge finishing machine for an opening in a garment; said machine comprising in combination with a body form on which a semi-finished garment can be mounted with the opening to be finished in juxtaposition to said machine, said opening being circular with respect to an axis; a main frame, a table mounted on the mainframe and movable to and fro, a work shaft rotatably mounted on the table co-axial with said axis, a sewing machine support fixed to the work shaft, cam means on a drive shaft rotatably mounted on the frame to engage and move the table to and fro in a path which represents the'profile of the garment edge to be finished in a plane at right angles to said axis, power transfer means coupling the work shaft and the drive shaft to effect rotation of the former, a sewing machine drive comprising a lay shaft mounted rotatably on the table co-axial with the work shaft and adapted to transfer a drive from a sewing machine motor when mounted on said table to a sewing machine when mounted on said sewing machine support and control means for ener
  • FIG. 1 is a perspective side view of the machine.
  • FIG. 2 is an enlarged view of part of FIG. 1 and FIG. 3 is an end view.
  • a body form support 1 shaped like the waist 2 to leg part of the body torso which isjuxtaposed a finishing machine 3.
  • the machine comprises a main frame 4 on which is mounted a movable table 5.
  • Two pairs of arms 6 connect the table to the frame 4 and on the upper surface of the table 5 there is secured a drive motor 7.
  • Rotatably supported in bearings on the underface'of thetable 5 is the outer of a pair of concentric tubes and through the centre of the inner tube there is a shaft 8.
  • the shaft 8 is slidably mounted in the inner tube and is connected by a cylinder 9 whereby the shaft 8 may be moved into and out of an aligning socket 10 in the body form.
  • the support 1 would in a production situation be ideally mounted on a rotatable work head so as to be indexed between various positions where the garment would be (a) loaded (b) sewn (c) removed. With such an arrangement, in order to accurately position the support I in the garment finishing position, a combination of the shaft 8 and the socket 10 would be essential.
  • the table 5 is moved to and fro so as to bring a sewing machine (not shown in the interest of clarity) mounted on a carrier indicated generally 11, into sew- -ing vicinity with the leg opening of the body form.
  • sewing machine could be a standard Singer sewing machine Type No. 246 K43 as commonly used in the garment industry or a similar machine.
  • the inner tube indicated 13 has a pulley l4 fixed to it, the pulley l4 drives the sewing machine through a belt.
  • the drive for the tube 13 is by means of the pulley l5 and belt 16 coupling pulley 15 to motor 7.
  • the motor 7 has an air cylinder operated clutch, the control cylinder and operating lever therefore are indicated generally by the numeral 160.
  • the sewing machine carrier 11 is rotatably mounted relative to the table 5 and is secured to the outer tube 17 of the concentric tubes. Also secured to the outer tube 17 is a wide spur gear 18. This spur gear 18 is driven by a gear 19 fixed to a shaft 20 rotatably mounted in bearings 21 and 22 on the frame 4. The shafts 20 is driven from a main drive shaft 23 through a pair of bevelled gears 24. From the foregoing it will be seen that rotation of the shaft 23 causes the shaft 20 to rotate thereby driving gear 18 through gear 19 with the result that the sewing machine carrier 11 rotates with the sewing machine needle concentric with the concentric tubes and the shaft 8 and hence the leg opening of the body form.
  • the gear 18 is made suffrciently wide so that as the table 5 is moved to and fro under the influence of cam means the gears 18 and 19 will remain in driving engagement.
  • the cam means comprises a rotating cam 26 fixed to the shaft 20 and a co-operating cam roller 27 mounted on the underface of the table 5.
  • the load on the cam and roller 26, 27 is lightened by means of a chain supported counter balance weight 28.
  • the to and fro movement of the table 5 can be modified as required to accommodate the shape of an edge to be hemmed.
  • the leg opening in the body form, when looked at in the direction of the shaft 8, is circular in cross section but the edge 29 of the opening when viewed at right angles to the axis of the shaft 8 is not in the one plane.
  • the sewing machine clutch arrangement 16a includes an air cylinder which must be operated at an appropriate time.
  • the sewing machine carrier 11 carries three air cylinder control valves indicated generally 30. These air control valves areoperated from cams (not shown) on plate 30a.
  • the valves 30 provide for normal sewing machine functions for example the operation of a thread cutter (in known manner) and the blowing away of threads and flufi".
  • the sewing machine may be of the known type which trims the edge of the garment just prior to hemming thereby requiring the trimmings also to be blown away.
  • the cam carrying plate 30a is moved into and out of alignment with valves 30 by an air cylinder 31 which with cylinder 32 of the assembly 16a and cylinder 9 are operated by valves 33 and earns 34 on the shaft 23.
  • a gland of known tyPe is mounted around tube 17, so that air can pass into an air take-off manifold on the tube 17 and from there to the valves 30 by piping.
  • the spool indicated 35 indicates elastic thread which may be sewn simultaneously around the leg opening of the garment with an overlocking stitch using cotton indicated 36.
  • an edge finishing machine for an opening in a garment, said machine being used with a body form on which a semi-finished garment can be mounted with the opening to be finished located adjacent said machine, said opening being circular when viewed along its axis and the garment edge having an uneven profile when viewed perpendicular to the axis, said machine including a main frame, and a support on the main frame for supporting a sewing machine to be used for performing the finishing operation, the improvement comprising a table mounted on said main frame and movable to and fro relative to the main frame, a work shaft rotatably mounted on the table co-axially with said axis, a main drive shaft rotatably mounted on the frame, cam means mounted on the drive shaft, a cam follower connected to said table and engaged with said cam means whereby rotation of the drive shaft moves said cam follower to impart said to and fro movement to the table, said cam means defining a configuration such that the movement of the table corresponds with said uneven profile of the edge of the garment, power transfer means coupling said work shaft and
  • the machine as claimed in claim 1 including first and second control means, said first and second control means being operated upon rotation of the main drive shaft to energize said sewing machine motor and to control other sewing machine operations.
  • control means comprises a plurality of air cylinders, air valves and cams, said valves and cams being brought into operative engagement as a result of the rotation of said work shaft.
  • the machine claimed in claim 1 including counterweights to facilitate the movement of the table.
  • a loeating bar comprising an axially movable shaft which is co-axial with the work shaft and mounted on said table, moving means to axially move said locating bar, and a socket opening in the body form in line with said axis and dimensioned to slidingly receive the locating bar.
