Definitions

  • ABSTRACT A sewing machine having a base plate and a head carrying a vertically reciprocable needle and means adjacent the needle for moving superposed layers of fabric through a stitching zone beneath the needle to form in the superposed layers of fabric an edge seam comprising a line of stitching extending in a stitching direction.
  • An intermediate plate above the base plate moves up and down into and out of contact with the base plate to grasp and release a lower layer of fabric between the intermediate plate and the base plate.
  • Needles convey superposed layers of fabric from the intermediate plate to the stitching zone in a direction perpendicular to the stitching direction.
  • a support plate extends from the stitching zone in the direction the conveying needles move and is connected to the intermediate plate.
  • This invention relates to an assemblage for the connection together of a plurality of sewable material layers, which in the region of an introduction position are orientated with respect to each other at at least one position, and are conveyed with the aid of a conveyor from the introduction position to the stitch-forming position of a sewing machine which has a guide device which is provided with a plurality of support plates each for the reception of a respective one of the said layers in the vicinity of the said stitch-forming position, the said layers when connected together being deposited lying on a support table at the stitch-forming position.
  • the invention provides an arrangement which makes it possible to place together upon one another the layers of sewable material to be connected with one another within an introduction position spaced from the stitch-forming position and so far as necessary to orientate them with one another, in order to bring them thus in common to the stitch-forming position so that each layer of material comes to lie upon the support plate appertaining to it.
  • the free end of the support plate is connected to the intermediate plate.
  • At least one preferably angularly-shaped abutment which is movable up and down and which after introduction of the material layers can be brought out of the subsequent path of movement thereof by a lifting motion.
  • the introduction of the two layers of material to be sewn can be facilitated and also may likewise be mechanized in a simple manner if the intermediate plate is disposed at an acute angle to the plane of the support table.
  • the invention further provides at the same time a conveying means which ensures secure guiding of the layers of material to be sewn from the introduction position to the stitch-forming position of the sewing machine.
  • the conveying arrangement of the conveyor arranged between the introduction position and the stitch-forming position is orientated perpendicularly to the stitch-forming direction and the conveyor comprises holder needles penetrating through the layers of material from the underside thereof, which needles are movable within a slot extending perpendicularly to the stitch-forming direction.
  • the layers of material to be sewn, thus held, can thereby be guided each with its respective end directly under the needle or the presser foot of the sewing machine, so that any contrariwise creasing is impossible.
  • the holder needles In the region of the stitch-forming position and the introduction position to be movable up and down as appropriate and to arrange them at the introduction position in relation to a device for holding down the layers of material to be sewn, which device is movable in alternation with the abutment.
  • the support table is sub-divided into two planes disposed at different levels in the region following after the stitch-forming position, and between these two table parts is arranged an outlet nozzle for an air jet for assisting the movement of the material which has been sewn together.
  • FIG. 1 is a plan view of the machine
  • FIG. 2 is a plan view of the engagement device
  • FIG. 3 is an elevation of FIG. 2 in the direction of the arrow F
  • FIG. 4 is a partial elevation of FIG. 2, in the direction of the arrow F'I,
  • FIG. 5 shows a sectional view of the device for conveying the cloth pieces towards the sewing machine
  • FIG. 6 is a plan view of a detail of the machine
  • FIG. 7 is a partial sectional view of the machine.
  • FIG. 8 is an elevation of the ejection device.
  • the automatic assemblage for the uniting of pieces of cloth or other materials by means of a seam along one of the sides of these pieces has a positioning surface 1 prolonged by the work table, which is subdivided into a part 2 situated at the same height as the surface 1 and a part 3 disposed at a slightly lower level. While the engagement frame 4 and the stop abutment 5 are fixed on the positioning surface 1 so as to be displaceable upwards and downwards, for example by means of jacks, beneath this surface 1, beside the engagement frame 4 there are provided the transport needles 6 (FIG.
  • the needles 6 constituting the drive elements of a device 6 which moves beneath the surface 1 and brings the cloth pieces towards the sewing machine 10.
  • the guide 11 which is constituted by three superposed plates, of which the middle plate 11' is prolonged to extend close to the engagement frame 4, in order to connect therewith.
  • the device for engagement and alignment of the edges of two pieces of cloth is composed of the engagement frame 4 and the angular abutment stop 5, which are disposed above the surface 1.
  • the frame 4 is constituted by a small plate equipped for example with two pairs of rods 19 subject to the action of two jacks 20 and passing through the surface 1. In the low position the frame 4 contacts the surface 1 and in the position raised under the action of the jacks 20 it is displaced vertically above the surface 1 by a distance permitting the free passage of a piece of cloth.
  • the abutment stop 5, constituted by an angular piece, is also connected by means of a rod 21 to a jack 22, one of the ends of the stroke of which applies the abutment 5 against the surface 1 and the other end of the stroke of which raises the abutment 5 from the surface 1 by a distance such that the passage of the pieces of cloth to be united can take place.
  • the descending and/or rising strokes of the frame 4 and/or of the abutment 5 can be effected by mechanical, pneumatic, electric, electro-magnetic or the like means.
  • the surface 1 and the intermediate engagement frame 4 are slightly inclined downwards in the direction of the abutment 5 so as to form a slight angle with the horizontal so that the assembly of the two pieces of cloth may slide by its own weight against the abutment 5.
  • blowing mechanisms l2, 12' which serve to assist the cloths in their displacement after their seaming.
  • the automatic assemblage as described comprises also the various contacts and detectors of known type which permit the starting and stopping of the various described elements for the realisation of the successive and/or simultaneous progress of the uniting, transport and stacking operations.
  • the automatic assemblage according to the invention is also characterized in that the surface for positioning the pieces to be united is at such a distance from the sewing machine that an assembly of pieces treated by the sewing machine in no way hinders the positioning of another assembly of pieces to be treated.
  • the direction of feed of the sewing machine preferably forms a right angle with the transport direction of the said machine.
  • the engagement frame 4 In the starting position, the engagement frame 4 is in the high position and the stop abutment 5 in the low po-. sition against the surface 1. Then the first piece of cloth is introduced between the frame 4 and the surface 1 until it abuts against the abutment 5. After this operation, the frame 4 is lowered against the surface 1 by operation of the jacks 20, which has the effect of immobilizing this first piece of cloth.
  • the needles 6 trip the displacement of the device 6' in the direction of the arrow F.
  • the device 6 actuates another contact, whereupon the needles 6 descend beneath the work table, the device 6 returns into its initial position, and a detection means chronologically causes the descent of the presser foot 17 of the machine, the starting of the machine 10, the raising of the thread cutter l8 and the starting up of the blowing mechhanisms 12, 12.
  • the pressure of the presser foot 17 is reduced. Then as the detection means 19 is also released, the machine 10 stops, the presser foot 17 is lifted, the blowers l2, 12' are stopped, the thread cutter 18 descends and the stacking system 13, 13', l4, 15 is set in action.
  • the automatic assemblage according to the present invention is applied particularly to the uniting of two pieces of cloth or similar materials by means of a seam, along the curve of one of their sides.
  • a sewing machine having a base plate and a head carrying a vertically reciprocable needle and means adjacent the needle for moving superposed layers of fabric through a stitching zone and beneath the needle to form in the superposed layers of fabric an edge seam comprising a line of stitching extending in a stitching direction; the improvement comprising an intermediate plate above the base plate for receiving a lower one of said layers of fabric beneath the intermediate plate and an upper one of said layers of fabric on top of the intermediate plate, means for moving the intermediate plate up and down into and out of contact with the base plate to grasp and release said lower one of said layers of fabric between the intermediate plate and the base plate, conveyor means for conveying said upper and lower layers of fabric in superposed relationship from said intermediate plate to said stitching zone for insertion beneath said needle, said conveyor means extending at an angle to said stitching direction, and a support plate extending above said base plate from said stitching zone in the direction of said conveyor means close to said intermediate plate in order to connect to said intermediate plate whereby said layers of fabric assembled one above and one below said intermediate plate will be convey
