  • a winding chamber is used on the periphery of which are arranged winding drums between which the fodder is wound into a roll, on a mandrel directed towards the outlet of the chamher.
  • shaping wheels are used in which the fodder is compressed to appear in the shape of slabs.
  • a further type of machine which comprises a series of open shaping passages, arranged radially in a circle about a conditioning chamber into which the fodder to be caked is introduced.
  • the fibrous substance is compressed progressively by being forced through a conduit of circular shape, the section of which decreases from its inlet to its outlet, said conduit being defined by a central wheel and a series of satellite rollers distributed about the said wheel at a progressively decreasing distance.
  • apparatus according to the invention in which pressure by laminating is used, enables the friction to be reduced and, consequently, the power of the motor required for driving the machine to be decreased.
  • FIG. 1 shows a view in elevation and partial section of one embodiment of apparatus for compressing fibrous substances, more particularly fodder,
  • FIG. 2 shows a detailed view of the members for adjusting a satellite roller
  • FIG. 3 shows a view in section along the line IIIIII of FIG. 2,
  • FIG. 4 shows a sectional view of a modification.
  • the apparatus for compressing fibrous substances shown in FIG. 1 comprises a framework 1 on which is mounted a supply hopper 2 which receives fodder cut to length and fed more particularly from an ensilage harvester.
  • openings 3, 3a On each side of the framework 1 are provided openings 3, 3a in which engage pistons 4, 4a of a supply press which ensures a first compression operation of the fodder and directs it into a conduit 5 of rectangular section.
  • the pistons 4, 4a are reciprocated by a rod 6 connected to a crank 7 secured to the piston 4 which itself drives a rod 9 and a crank 10 secured to the second piston 4a via a second crank 8.
  • the supply press has double pistons, but it will be apparent that any of the known type of press could be used.
  • the conduit 5 is extended into a further conduit 11 for compressing the fodder in accordance with the invention.
  • This conduit 11 is of semi-circular shape and its crosssection decreases from the inlet 11a to the outlet 11b.
  • the conduit 11 is defined by a central wheel 12 and a series of satellite rollers 13a to 13i distributed about the said wheel at a progressively decreasing distance.
  • the central wheel 12 is fixed to a shaft 14 which is mounted to rotate on the frame 1 of the machine, the wheel 12 being rotated by a motor having reduction gearing at a speed of 4 to 5 rpm, via the shaft 14.
  • the central wheel 12 has a peripheral channel defined by two flanges 15, 15a, and a base 16 the surface of which is grooved to ensure better feed of the product.
  • the flanges 15, 15a of the wheel 12 are partially engaged satellite rollers 13a to l3i which form, with the flanges 15, 15a, the conduit 11 of the compression device.
  • the flanges 15, 15a are intended to prevent lateral creep of the fibrous substances under the increasing pressure caused by the satellite rollers 13a to 131'.
  • FIGS. 2 and 3 show details of the assembly and how the satellite rollers exemplified by the roller 132 are mounted.
  • Roller 132 is fixed to a shaft 17 by means of a key 18, the shaft 17 being mounted to rotate on roller bearings 19, 19a engaged in rings 20, 20a capable of sliding between the guide surfaces 21, 21a of the frame.
  • the rings 20, 20a are fixed to or integral with threaded rods 22, 22a which are screwed into nuts 23, 23a rotatably mounted and held captive in cross members 24, 24a fixed to the frame 1 by means of screws 25.
  • This arrangement enables the axial spacing between each roller 13 and the central wheel 12 to be adjusted in such a manner as to cause the section of the conduit 11 to vary from its inlet to its outlet.
  • a toothed pinion 28 which is connected by a chain 29 to a pinion (not shown) fixed on the shaft 14 for driving the central wheel.
  • the speed of rotation of the central wheel 12 and satellite rollers depends on, and remains in permanent relation to, the supply speed set up by the press constituted by the pistons 4, 4a.
  • a guide bar shown at 30 in that Figure having a substantially triangular cross-section and which fills the space between the two consecutive rollers, to prevent or minimise any local piling of fibrous substance prejudicial to the flow of the material during agglomeration.
  • the guidel bars 30 automatically assume their position between the satellite rollers 13 and are not effected by the adjustment of the rollers.
  • the face 36 of the guide bars 30 which is in contact with the fibrous substance is hardened and polished to ensure good sliding.
  • bearing is not effected directly between the rings 31, 310, as described hereinbefore but by means of the guide bars 30a, 30b, 30c.
  • the guide bar 30a rests, by a shaft 43, against a semicylindrical bearing of a flat support member 44 in which are engaged and pinned rods 45a of two sockets 45 each enclosing an insert 46 having a hemispherical bearing which rests against a hemispherical head 47 of a threaded rod 48 mounted in adjustable manner in a threaded hole of a shaft 49 secured to or integral with the flanges la of the frame.
  • the rod 48 is provided at its end with a hexagonal head 50 for adjustment and a locking nut 51 is screwed onto the threaded part.
  • the shaft 43 may move slightly from right to left in dependance upon the position of the guide bar 30a which is resting on the two sets of rings 31, 31a coaxial to the two adjacent satellite rollers adjusted to any position whatsoever.
  • the shaft 49 which carries the: threaded rods 48 is fixed by welding to the frame and this arrangement necessitates a hemispherical bearing point 46, 47.
  • the end guide bars 30b, 300 these are simply mounted by their shaft 43 on a flat bearing member 44 in which the ends 52 of threaded rods 53 are engaged and pinned, said rods being mounted in adjustable manner in a shaft 54 capable of turning in the flanges lb of the frame.
  • the threaded rods 53 are provided at their end with a hexagonal head 55 and a locking screw 56 is screwed onto the threaded part.
  • a scraping device formed by a fixed member 37 secured to or integral with the frame, in contact with the base 16 of the central wheel 12 and a member 38 movable under the action of a spring 39, and mounted on a rod 40 fixed at 41 to the frame.
  • the moving member 38 which is supported by two flat washers like rings 31, 31a is mounted like the guide bars 30 in an almost horizontal manner with a slight play with respect to the last satellite roller.
  • This member 38 is arranged in a manner to provide a space 42 between the fixed member 37 and the moving member 38 for the passage of the product at the outlet from the device which is in the form of a ribbon of rectangular section which may easily be broken if necessaryy.
