Definitions

  • the present invention may be said to have for its object rapidly and economically to treat a flexible material faced with thin wood veneer so as to render the veneer limp or, in other words, destroy its capacity for curling, without marring the appearance of the surface of the veneer when the product is laid flat.
  • Figures 1, 3, 5, 7 and 9 are diagrammatic views illustrating the assembling of a flexible sheet, comprising a backing and a facing of wood veneer, and elements by means of which the splitting of the veneer ma be brought about in several different ways; igs. 2, 4, 6, 8 and 10, are views similar to Figs. 1, 3, 5, 7 and 9, respectively, illustrating a second step in the process; Fig. 11 is a side view of a machine for carrying out the method illustrated in Figs. 5 and 6; and Fig. 12 is a vertical section through the machine.
  • A. represents a flexible backing faced with thin wood veneer B; both the backing and the veneer being shown on a greatly enlarged scale.
  • 1 is a bar having at the top a more or less blunt edge 2; the thickness of the bar being also exaggerated.
  • T e veneer usually splits at a considerable number of places along the bar, because the grain seldom runs along straight parallel lines across the sheet; the more or less radial lines I) in Fig. 2 indicating such breaks in the veneer.
  • the curved part of the sheet is flattened again the breaks or slits will close and be invisible for all practical purposes.
  • the veneer, so treated has been rendered limp and impotent so far as the capacity to curl is concerned.
  • a belt or band of flexible mate rial may overlie the veneer while the bending is in progress.
  • a belt or band is the veneered sheet from rubbing on the edge bar.
  • the veneered sheet may be moved continuously so as proressively to draw it across the edge or ar. owever, an intermittent feed ma be employed.
  • an intermittent feed may be employed.
  • the veneered sheet being in osition between the members 1 and 5, as in icated in Fig. 7, the plunger is pressed down, bending the sheet over the edge or bar as shown in Fig. 8, producing the same effect as the operations illustrated in Fi s.
  • Figs. 9 and 10 there is illustrated a slightly different modification.
  • the .bar 7 terminates at the top in a comparatively sharp edge 8.
  • the plunger 9. above the bar, has a vertical openingor passage 10 registering with the bar. When the plunger is forced down upon a veneered sheetlying on the bar, it bends the sheet sharply over the edgeof the bar, causing the veneer to crack,
  • the sheet must be fed intermittently when it is treated in either of the ways illustrated in Figs. 7 to 10, the feeding of the sheet bein e ected while the plungers are up.
  • Figs. 11 and 12 I have illustrated a machine for carrying out the process illustrated in Figs. 1 to 6, particularly Figs. 5 and 6.
  • the machine comprises two parallel side frames 15 and 16. J ournalled in the frame, with their axes of rotation in the same vertical plane, are three long rollers 17 ,18 and 19.
  • the roller 18 is driven in any suitable way as, for'example, by a belt passing over a suitable pulley 20 on theroller shaft 21.
  • On the shaft 21 is a gear wheel 22 mesh ing with a similar gear wheel 23 on the shaft 24 of the roller 19; Consequently,
  • the roller 25- as at its ends trunnions 27 that ride in long slots 28 inclined to the vertical. The high ends of the slots are nearest to the rollers, 17 to 19.
  • the roller 25 will therefore position itself as far away from the rollers 17 to 19 as the slots 28 will permit, when free to do so.
  • the roller 26 is journalled at itsends in blocks 30 slidable in horizontal bearings 31; the blocks being adjustable toward and away from the rollers 17 to 19 by means of suitable screws 32.
  • a long bar 33 parallel with the axes of rotation of the rollers.
  • the bar is shown as mounted on suitable brackets 34 on the frame. .
  • the bar is shown as being triangular. in crosssection, with the a exat the top:
  • a broad endless elt 35 extends aroundthe rollers 17, 18 and 25 extending, between the rollers 18 and 25, over the top of the bar. 36. extends over' -the A second endless belt rollers 19 and 26 and over the bar. The arts are so proportioned that those parts 0 the belts from a point near the roller 25 to the point where one of the belts passes under the roller 18 and the other passes over the roller 19, lie, parallel with each other and tend tov come into contact with each other.
  • veneer is partially disintegrated in the manner heretofore explained.
  • the trunnions on the roller 25 are at some distance from the lower ends of the slots, so that this roller may be said to be suspended in a loop of the belt 35, thereby kee ing this belt under a constant tension.
  • the tension of the belt 36 may be adjusted by means of the screws 32.
  • I claim 1 The method of making pliable a sheet composed of a flexible backing faced with wood veneer, which consists in splitting the veneer to divide the face thereof into many narrow filaments whose long edges follow the grain of the wood.
  • the method of progressively partially disintegrating the veneer on a sheet, consisting of a flexible backing and a facing of wood veneer, so as to render the veneer limp which consists in manipulating the sheet so as to place one narrow section of the veneer after another, under sufficient stress transversely of the grain to cause the veneer to split.
  • a bar having an edge
  • two endless belts having sections in contact with each other passing across the bar and bent over said edge, and means for driving said belts so as to cause said sections to travel in the same direction.
  • a horizontal bar having an edge at the top, a long endless belt surrounding the bar and resting on said edge, the said belt extending downwardly on opposite sides of the bar, a, second endless belt above the bar, a portion of the second belt in the vicinity and on opposite sides of said edge resting on the first belt, and means for driving said belts so as to cause the contacting parts of the belts to move in the same direction.
