Definitions

  • the present invention relates, in general, to textile machinery and, in particular, to apparatus for splitting tubular knit cloth.
  • tubular knit cloth is split by inserting an internal spreader into the cloth.
  • the internal spreader has rolls which engage the inside surface of the cloth. Normally, the spreader is clamped in a horizontal position by edge drive rolls. The cloth is held between the external edge drive rolls and the internal rolls of the spreader. The edge drive rolls are driven and move the cloth across the spreader.
  • a set of nip rolls pull the cloth from the spreader at the delivery end of the spreader.
  • a rotary knife is placed at one edge of the cloth between the edge drive rolls and the nip rolls. The cloth is split as it is driven past the rotary knife.
  • a preferred form of the present invention to be described in more detail hereinafter includes a cutting tool for splitting a tubular knit cloth and conveying means for feeding a single thickness of the tubular knit cloth to the cutting tool.
  • the conveying means are so disposed as to lie within the tubular knit cloth as the tubular knit cloth is fed to the cutting tool.
  • means disposed behind the back edge of the cutting tool for supporting the conveying means and means adjacent both sides of the cutting tool for grasping the split edges of the cloth after it has been split by the cutting tool and for drawing the cloth past the cutting tool.
  • FIGURE l is a perspective view of a portion of a cloth splitting machine constructed in accordance with the present invention.
  • FIGURE 2 is a plan view of cloth splitting apparatus constructed in accordance with the present invention.
  • FIGURE 3 is a sectional View taken along line 3-3 of FIGURE 2;
  • FIGURE 4 is a sectional view taken along line 4 4 of FIGURE 2;
  • FIGURE 5 is an enlarged view of a portion of the apparatus of FIGURE 1;
  • FIGURE 6 is a sectional view taken along line 5*6 of FIGURE 5.
  • tubular knit cloth designated by reference numeral 10
  • tubular knit cloth is conveyedV horizontally from a conventional knitting machine, not shown, to a cutting tool such as a rotary knife 11 by means of a pair of V belts 12a and 12b.
  • the rotary knife 11 is driven by means of an endless belt 32 which, in turn, is driven by a suitable drive, not shown, coupled through a shaft 33 to a pulley 34.
  • the rotary knife 11 is mounted on a framework designated generally by reference numeral 15 by means of a pair of vertical arms 41a and 41!) having angle brackets 42a and 42b, respectively, at their upper ends.
  • the arms 41a and 41!) extend upward from a horizontal base member 17.
  • the V belts are driven by a suitable drive, not shown, coupled to one of two pulleys 13 and 14 having dual grooves to engage the two V belts.
  • the pulleys 13 and 14 are mounted in the framework 15.
  • the pulley 13 is supported by a pair of vertical arms 16a and 1Gb extending upward from the horizontal base member 17, while the pulley 14 is supported by a pair of Vertical arms 13a and 1819 extending upward from the horizontal base member 1'7.
  • the framework 15 is supported within the main structure of the splitting machine by means of a pair of brackets 19a and 1gb which are aixed to the horizontal base member 17 at a point behind the back edge of rotary knife 11.
  • An idler 2t is provided for supporting the V belts 12a and 12b at some point intermediate the pulleys 13 and 14 and for adjusting the tension of the V belts in the event they stretch. Such an adjustment may be effected by pivoting a pair of arms 21a and 2lb which support idler 2G about a bolt 22 or by moving the bolt 22 along a slot 23 in the horizontal base member 17.
  • a brush roller 24 precedes the V belts 12a and 12b.
  • the purpose of the brush roller 24 is to have the cloth 10 engaged by a relatively smooth circular surface rather than by a surface having sharp edges such as the pulley 13.
  • the brush roller 24 is supported by a pair of vertical arms 30a and 36h extending upward from the horizontal base member 17.
  • the brush roller ⁇ 24 is proviided with a guide rail 31 which prevents the cloth 10 from falling between the sides of the brush roller and the arms 30a and 50i).n The rail 31 provides the same protection at the pulley 13.
  • the cloth 16 is allowed to bag down and is placed on the brush roller 24.
  • a fan 25 is provided for blowing air into the tubular cloth 1t) so as to balloon the cloth thereby facilitating the guidance of the cloth to the rotary knife 11.
  • the dimensions of the tubular cloth 10 and the framework 15 are such that the framework lies within the tubular cloth on its approach to the rotary knife 11 with the result that the cloth is fed to the knife in a single thickness.
  • the rotary knife 11 makes a single cut along a line 10 at the top of the cloth 10 in splitting the cloth. Upon being cut, the cloth 1t) drapes beneath the framework 15.
  • the cloth 10 After the cloth 10 is split7 it is guided around a pair of guides 26a and 2612 adjacent both sides of the rotary knife 11 to a plurality of pairs of pin plates 27a and 27b.
  • the newly split edges of the cloth 10 are picked up by the pins of the pin plates as the cloth is caught between the pin plates and a pair of rotary brushes 28a and 28h.
  • the guides 26a and 2617 prevent curling of the nev/ly split unfinished cloth.
  • the rotary brushes 28a and 28h are supported from angles at the top ends of the guides 26a and 26h, respectively, which, in turn, are affixed to the angle brackets 42a and 42]), respectively.
  • the pin plates 27a and 27b are arranged on a pair of standard endless roller chains 29a and 29h, respectively.
  • the endless roller chain 29a runs between a first sprocket 35a and a second sprocket 36a, while the endless roller chain 2% runs between sprockets 35.5 and Seb.
  • the drives to the two roller chains may be imparted through a pair of shafts 43a and 43h secured to the sprockets 35a and 35b, respectively, by means of flanges 44a and 44h, respectively.
  • the pin plates 27a and 27b draw the split cloth past and away from the rotary knife i 11 in the same direction in which the tubular knit cloth is fed to the rotary knife.
  • FIGURES and 6 show the details of the pin plates j 27a and 27b and the manner in which the pin plates are arranged on the endless roller chains 29a and 29h.
  • the pin plate 27a having a plurality of pins 37, is secured to a lug 38 extending downl ward from the sideplate il of a link by means of a bolt i 39 and a nut di).
  • the pin plates 27a are so dimensioned as to be secured to every other link in the chain 29a This arrangement permits the pin plates to negotiate the turns at the sprockets 35a, 3512, 36a and 3511.
