Definitions

  • This invention relates to the baling of long industrial fibers and more specifically to a meth: od of baling long industrial fibers in which a mass of fibers is arranged in a horizontal layer with the fibers running lengthwise of a baling box, the
  • the invention also includes the bale produced by the above described process, said bale comprising a plurality of. superimposed layers of fibers having their feet at one end of the bale and being folded obliquely back upon themselves at the opposite end of the bale, the folds and the feet. of the fibers insuccessive layers being reversed with respect to adjacent layers, all as more fully and hereinafter set forth and disclosed.
  • An object of this invention is to form bales of long industrial fibers with the-fibers folded in such a manner that the tendency of the fibers to break in the fold is eliminated.
  • a further object of the invention is to bale industrial fibers in such a manner that .a greater weight of fibers can be compacted within the same cubic dimensions than in previous baling processes.

  • Fig. 37 is an end view of a bale having oblique foldsin-which the folds of successively superimposed layers are folded obliquely in opposite directions togive a herringbone pattern.
  • the trestle used in my process comprises two ends I connected by a cylindrical top 2 over which fibers are spread. Extending from one side in a horizontal direction is a plank 3 and on the opposite side is a gutter or indentation 4. Mounted directly below the gutter and protruding beyond the edges of the ends are arms 5. The width of the trestle corresponds to the width of the baling box and accordingly to the width of the finished bale. As shown in Figs.
  • the clamping device employed for removing fibers from the trestle and for transferring them to the filling frame, consists of a bar 6 having a longitudinal recess on one side which is adapted to receive the rod 1 with a layer of fibers in between.
  • Figures 6, 7 and 8 show a filling frame comprising two longitudinal sides 8 supported by the vertical ends 9. The sides 8 are connected at each end by a slanting board It. Each of the two longitudinal sides has an elevation H and a notch l2 at both ends. 7
  • a layer of fibers is spread evenly across the trestle with their thick ends resting on the plank 3 and their thin ends extending slightly below the gutter 4.
  • Thebar 6 is placed in the gutter 4 behind the layer of fibers and the layeris gripped between the bar (3 and the rod 1 at a distance from the feet of the fibers equal to the length of the baling box as shown in Fig.10.
  • the layer of fibers is then transported to the filling frame as shown in Fig. 13.
  • Fig. 25 is shown a filling frame modification comprising reinforcing plates l4, a space 15, holes l6, gates l1 and ribbed clamping plates I9 and 2D, the plates having handles 2
  • Folding the fibers is advantageous since a great deal of waste is prevented which would other-'5 wise result if the'thin ends were cut to form fibers of uniform length.
  • the layers arranged in this manner are compressed in the baling box and as explained above it is advantageous to compress the layers into as'small a cubic content as possible to save freight charges.
  • the use of high pressures during pressing has not been possible owing to the fact that the fibers when folded vertically, as shown in Fig. 18 are likely to crack when straightened as shown in Fig. 20.
  • bales made of layers folded in this manner are compressed to a smaller cubic content than bales made of layers folded accordingto prior methods, when using the same pressure;
  • a second more advantageous method consists in arranging a mass of fibers in a layer across: a support, such as a trestle (-Figs; f to 3 and-6130 8) with their feet hanging on one side, as Fig; l0 and their thin ends on theother side.
  • the soarrangedfibers arethen picked 'up with a pair er gripping bars (Figs. 4, 5, ll and 12) at the point-wherethey areto be folded, that" is, at. a point which is a distance from the feet corresponding to the length of the baling box. Two workmen are required, one at each end of the gripping bars.
  • the gripping bars preferably consist of a rod 1 which is placed in the bight of the fold and a bar 6 having a longitudinal recess on one side which is adapted to receive the rodwith the layers of fibers in between. While the layer of fibers is held between the gripping bars, the latter being grasped by the workmen in one hand, one of the workmen pulls the thin ends of the fibers toward himself and the other the thick ends while both relax their grip on the gripping bars. This causes the fibers to slant obliquely in the fold. The layer of fibers held by the gripping bars in the manner described is then transferred to the baling box, as in Fig. 13.
  • the baling box which is equipped with a ram may also be equipped with a baling frame (Fig.
  • the required oblique displacement of the fibers in the fold can be accomplished with the aid of a pair of fiuted bars l9 and 2b in the following manner.
  • These fluted bars with the fluted sides facing each other are placed in a support such as the filling frame as in Figs. 25 to 28 in such a manner that they can be moved longitudinally with respect to each other.
  • the above described gripping bars with the fiber held between them are then clamped between the fluted barsand the latter are then moved longitudinally with respect to each other.
  • the pressure on the clamping bars is released during this movement so that as a result of the operation the fibers are given the desired oblique displacement.
  • the process which comprises arranging a mass of fibers in a horizontal layer in abaling box with the fibers running longitudinally, the feet of the fibers being at one end and the fibers being folded backward upon themselves at the other end of the box, displacing the fibers so that in the fold they slant obliquely, arranging a second layer of fibers on top of said first layer but with the fold and the feet of the fibers being reversed relative to the first layer, arranging a third layer of fibers on top of said second layer with the fold and the feet of the fibers again being reversed, the fibers in the fold of said third layer being displaced so that they slant obliquely in a direction opposite to that of the fibers in the fold of said first layer, adding additional layers of fibers to the box with the folds and feet of the fibers being reversed in position in successive layers and pressing the layers of fibers into the box to form a bale having superposed folds of fibers in layers interspersed
  • a bale of long industrial fibers comprising a plurality of superposed layers of fibers having their feet at one end of the bale and being folded back upon themselves at the opposite end of the bale, the folds and the feet of the fibers in successive layers being reversed with respect to adjacent layers, the fibers in said folds slanting obliquely whereby cracking of the fibers in the folds is prevented, the said layers of fibers being compressed together.
  • bale of claim 4 wherein the fibers in 5 the folds at either end of the bale all slant obliquely in the same diagonal direction.
