Definitions

  • Cl A4lh 1/00 pattern to be ut n means to move the replica to cor- [58] Field of Search 33/1 R, 11; 26/70 re p n wi h the l ying out of the fabric and indicia means to correlate the positions of imperfections in the [56] References Cited cloth with the replica of the pattern to be cut.
  • the present invention relates to a cloth laying machine for laying out webs of fabric on a table in order to manufacture cutouts thereof which correspond to a given cutting pattern, the machine being provided with means for supporting a supply of fabric such as a bolt of cloth to be reciprocatingly driven over the table surface.
  • the object of the invention is therefore to improve the structure of cloth laying machines to the extent that when the single webs of fabric are laid out on the table it can immediately be determined if the imperfections in the fabric will be located inside or outside of a portion of the fabric to be discarded later.
  • This object can be realized, according to the invention, by providing the carriage with a design of the cutting pattern and means to correlate movement of the design with movement of the carriage in order to determine where it is essential to cut out the imperfections.
  • FIG. I is an elevational view of the cloth laying machine of the invention.
  • FIG. 3 is a simplified plan view of a driving mechanism.
  • FIG. ll shows a cloth laying machine, according to the invention, indicated generally by numeral 10.
  • the cloth laying machine comprises a carriage 12 which can be reciprocatingly driven on a table 18 by means of two pairs of wheels 14 and 16.
  • the reciprocating movement of carriage I2 on table I8 can either be done manually or by a power driving means (not shown) such as an electric motor to produce the displacement of the carriage, in which latter case reversing elements (also not shown) are mounted at both ends of the table to automatically produce the reversal of the direction of movement of the machine 12.
  • a support means 22 for rotatably supporting a bolt of cloth 24 is mounted on an upper platform 20 of the cloth laying machine 10.
  • This support means 22 can be oscillated 360 by means of a centrally arranged, vertical pedestal 26.
  • Each one of the two diverging lower ends of the support means 22 is provided with a deflecting roller 28 and 30, respectively, so that the fabric of bolt 24, which is to be laid out in layers on table 18, is conveyed over one of these deflecting rollers, around an additional deflecting roller 32 and to a winding off roller 34. From the winding off roller the fabric is conveyed to a guiding device 36 located in its starting position at the lower end of carriage 12 shown at the right end of the carriage in FIG. 1.
  • the web of fabric wound off from bolt 24 is deflected in such a manner by the guiding device 36 that it is laid out on the table surface, said guiding device being adapted to be moved up and down in the vertical direction on the carriage 12 by means of guides.
  • the guiding device 36 is additionally provided with a projecting positioning ruler 38 which is parallel to the table surface and whose purpose will be explained later on.
  • the automatic vertical height adjustment of the guiding device 36 and, consequently, of the positioning ruler 38 is necessary due to the fact that during the movement of the carriage 12 on the table 18, the height of the pile of the laid out webs of fabric gradually increases.
  • the side of carriage l2 opposite to the winding off roller 34 is inclined and is adapted to support an endless belt 44 mounted around two rollers 40 and 42 which are journalled in respective bearing brackets.
  • the belt 44 is provided with an endless cutting pattern design 46, which exactly corresponds to the cutting pattern which is to be applied later on the pile of laid out webs of fabric, for the purpose of cutting out the individual cloth portions.
  • a second positioning ruler 48 is mounted above the upper portion of belt 44 and extends over the whole width of the belt.
  • both positioning rulers 38 and 48 are provided with graduations 50 and 52, respectively, which correspond to each other.
  • the scale of both graduations 50 and 52 is the same.
  • the scale of the graduations on the second positioning ruler 48 can be different than on the positioning ruler 38.
  • the actuation of the belt 44 and of the winding off roller 34 is accomplished by the reciprocating movement of the carriage 112.
  • a driving pulley 54 is secured to one of the wheels 14 which is visible in FIG. I.
  • the driving pulley 54 is connected to another driving pulley 62 by means ofa belt, or chain, 56, and by means of deflecting pulleys 58 and 60 which are located in between.
  • Another pulley 64 is fixedly secured to the first deflecting pulley 58 and by means of an intermediate pulley 66 it drives two rollers 40 and 42 which are connected to each other by means of a belt 68.
  • This driving arrangement causes the direction of movement of the belt 44, carrying the cutting pattern design 46, to change when a change occurs in the direction of movement of carriage 12.
  • a shiftable, twoposition clutch 70 is provided on the second driving pulley 62, by means of which the winding off roller 34 is driven in clockwise rotation when the carriage 12 moves to the right in FIG. 1.
  • the shiftable clutch 70 is disconnected from the second driving pulley 62 and is now coupled with a driving pul- -ley 72 mounted on a common shaft with pulley 62,
  • an electromagnetic clutch could also be used, particularly in the case where a reversible electric motor is used to automatically produce the reciprocating movement of the carriage 12, in which case the position of the electromagnetic clutch will be reversed when the polarity of the current supplied to the motor windings is reversed.
  • the endless belt 44 is provided with a design of the cutting pattern 46, as already mentioned, which exactly corresponds to the cutting pattern which is to be applied to the laid out webs of fabric in order to guide the workmen in cutting out the cloth.
  • this faulty area P (FIG. 2) comes under the positioning ruler 38 during the laying out operation, this faulty area can also be located on the cutting pattern 46 by means of positioning ruler 48. As shown in FIG. 2, this faulty area P, lies partially within a cutout so that a corresponding strip can now immediately be cut out of the faulty web of fabric, and the cut ends can be overlapped.
  • the roller 42 is provided with a coupling means 76 having a hand wheel 78 which permits the cutting pattern 46 to be manually turned to its starting position.
  • the positioning ruler 48 associated with the cutting pattern 46, is fixedly mounted on the carriage 12.
  • this positioning ruler can be reciprocated, by means of a belt drive or a similar device, in accordance with the direction of movement of the carriage, in which case the cutting pattern 46 will be fixedly mounted on carriage 12, for example in the form of a plate or a film.
  • Apparatus for laying out a plurality of layers of cloth on an elongated cutting table comprising carriage means reciprocatorily movable along the length of a cutting table, said carriage means including means to support a supply of cloth to be laid out on a table during said reciprocatory movement, pattern means reproducing the outlines and relative positions of pieces of cloth to be cut out when the layers of cloth are in position on a table, and correlation means to continuously disclose the relative position of an imperfection in the cloth with respect to the outlines of pieces of cloth to be cut out, said pattern means including two elements, one of said two elements comprising a sheet bearing outlines of the pieces of cloth to be cut out, the other of said two elements comprising indicia means disposed to coact with said sheet, and said correlation means including means to move one of said two elements continuously with respect to the other of the two elements in synchronism with movement of the carriage means during laying out of said fabric.
  • one of said two elements of the pattern means comprises a visual representation of said outlines and the other of said two elements comprises scale means positioned for visual comparison with said one element.
  • said visual representation includes an endless sheet of material, and a pair of rotatably mounted support rollers for said sheet, said carriage means including a supporting wheel in contact with a cutting table, driving means connecting said supporting wheel with one of said rollers, scale means positioned adjacent said sheet, and corresponding scale means adjacent the cloth being fed to a table, both said scale means extending transversely with respect to the direction of movement of the elements with which they are associated.
  • said driving means includes belt means connecting said supporting wheel with said one roller, and also includes belt means and winding off roller means for feeding cloth to a table in response to movement of the carriage means, said last named belt means including reversing clutch means to permit cloth to be fed in either direction of movement of the carriage means.
