  • both sewing machines 20, 21 are provided with conveyers 26, 27 which, after the material piece has left the region of the delivery conveyers l6, 17, provide for the advancing of the material through the sewing stations.
  • the conveyer bands 26, 27 move the material pieces and press them on a glide surface provided within the sewing stations and thereby one attains an advancing movement of the material through the friction coupling between the conveyer bands 26, 27 and the material itself.
  • Both conveyer bands 26, 27 are arranged parallel with respect to each other and serve at the same time as the removal means from the sewing stations. There are a pair of conveyer bands 29, 30 arranged subsequently and which are identified as an intermediate conveyer 28.
  • the intermediate conveyer 28, as indicated in the drawings, is a kind of extension of both of the conveyer bands 26, 27.
  • the folding apparatus will be supplied alternatively from both of the sewing stations. Since both of the sewing stations are arranged in a mirror-like manner with respect to the folding station, it is necessary that the intermediate conveyer band 28 is driven by a reversible motor and that it be moved alternatively from left to the right and from right to the left when viewed in respect to FIGS. la 1c. It is noted that the delivery speed of the intermediate conveyer 28 is substantially larger than that of both of the conveyer bands 26, 27.
  • an individual conveyer band could be provided for each delivery direction and which then would be arranged as a pair closely adjacent to each other and could be controlled, for example, by a photocell device from the associated sewing station to run the one which is to receive a good.
  • a transfer device for the delivery of the piece of material on which the hemming has been already performed, to the input conveyer of the folding station. It is noted that the delivery direction of such device is substantially perpendicular with respect to the delivery direction of the intermediate conceyer band 28.
  • Such transfer device of the material pieces consist, as can be seen in the illustrated embodiments, of at least a pair of clamps 3l .(See FIG. 5) arranged along the sides of the delivery conceyer 30, and which clamping means 31 consists each of a fixed member 32 and a movable member 33.

  • Both clamping means 31 are fixedly coupled with a chain 39 passing over a pair of guide rollers 37, 38 and which are driven by reversible motor (not shown) the reversing operation of which is performed by a further photocell arrangement and which performs the positioning of the clamping device 31 between its right end position, illustrated in FIG.
  • clamping means 31 In the region of the left end position of clamping means 31 is a boss 40 provided for the movable member 33 of each of the clamping means 31 for opening up the clamping means 31 before its returning movement to its right end position and to hold the piece of material for a short time fixed on a supporting surface 41.
  • the supporting surface 41 is followed next by a folding device which performs the first folding operation of the material and, which includes a folding bar 43 supported in a carrier 42 and a pair of associated folder pushers 44.
  • the folder pushers 44 are carried by oscillating arms 45 which are journaled on a support 46 and which are driven by a crank drive 47, not shown in the drawing in detail, since crank drives are known per se.
  • This first folding station of the folding apparatus is followed by several other folding stations, as illustrated in the drawing, in which the textile piece which has already been folded along its longitudinal sides will become folded further so at the end of the folding process it will attain a ready to pack size.
  • the further folding stations comprise folder blades 48, 50 which are inserted into a partition.
  • the advancing movement of the material from the first to the second folding station is performed by usual delivery conveyers (not shown) while from the second to the next folding station is performed by the folder blades 48, 50.
  • the folded material in its final shape is removed from the apparatus by means of a removal conveyer 49.
  • the overall apparatus operates as follows:
  • both delivery conveyers 16 and 17 are turned on and they deliver the cut strip material into the region of the sewing machines 20, 21 which on both of the cut edges of the strip perform a hemming operation.
  • the piece of cut material will pass over to the conveyer bands 26, 27 which are arranged subsequent to the conveyer bands 16, 17 and such transition occurs as long as the sewing stations 20, 21 are operational and until the back end of the strip material, when viewed in the delivery direction, has left the sewing machines 20, 21.
  • the intermediate conveyer band 28 takes over the material and the conveyer bands 29, 30 of which run at a higher delivery speed then the conveyer bands 26, 27 and .will cause an advancing of the material and will remove it into the region of the folding apparatus. Looking at FIG.
  • the removal station 2 of the second sewing apparatus gets a similar strip material pulled through which then in the cutting station becomes severed into an individual piece in a similar manner as above and becomes led into the second sewing station of the overall apparatus which then will hem both of the cut edges of the material, as above.
  • the first piece of the material in the second sewing station has just left with its back end the station and becomes engaged and held by the intermediate conveyer band 28 now running in the opposite direction with respect to its first running direction and delivers the material into the region of the transfer device.
  • the piece of material is engaged by the clamp means 31, as described above, and is spread out on the supporting surface 41 and then delivered further to the folding stations of the folding apparatus.
  • the second piece of material has left the first sewing station and becomes engaged and held by the intermediate conveyer 28 and delivered into the region of the folding apparatus and becomes there folded.
