Abstract: An apparatus for treating continuous unexpanded structural honeycomb material formed of permanently creasable material comprises rollers for drawing the material in the expansion direction whilst compressing it perpendicularly thereto so that it adopts a second unexpanded state. A guide receives the advancing material and permits slight re-expansion and a double acting severing device, e.g. a circular blade driven by a double-acting ram in forward and return strokes, severs the slightly re-expanded material to form cut lengths. The severing device may be located at the position of a guide of compact form, or at the outlet end of a guide in the form of a channel having at least one resilient wall. A receiving surface, formed in part by a conveyor belt may be provided to receive the cut lengths and allow them to expand. Guides for the expanded material may be arranged to discharge the expanded material from the receiving surface.

Abstract: A rotary compacting machine using rolling-compressing techniques in which loose fibrous material is rolled into a dense continuous cylindrical core in a compression channel. At the discharge end of the compression channel the continuous core is cut to the desired length individual rolls.The improved cutting mechanism, subject to this invention is self-actuating, and it is capable to maintain the desired cut-length of the individual rolls without any supplementary metering or sensing elements. It overcomes the mechanical difficulties which were inherent in the cutting systems of prior art machines.

Abstract: In a hydraulic scrap shearing machine having scrap shears at one end of an open feed channel which is wider than the mouth of the shears and which has one of its opposite side walls movable towards the other to squash scrap placed in the feed channel to a final width which will allow the scrap to be pushed by a feeder ram along the feed channel and into the mouth of the shears, the movable side wall is formed by the working faces of a main hydraulic ram and an auxiliary hydraulic ram which can be advanced independently of the main ram, the working face of the auxiliary ram being situated adjacent the mouth of the shears and being shorter than the working face of the main ram measured in the direction of the feed channel. Normally the main and auxiliary hydraulic rams are operated so that their working faces, together forming the whole of the movable side wall, are advanced and retracted together.

Abstract: A shredding system for reducing automobiles and other large pieces of metal scrap to fragments includes a feed chute for receiving the scrap and a shredder to which the chute directs scrap. A track feeder is located above the chute for both crushing the scrap and for controlling the speed at which it is introduced into the shredder. The vertical position of the track feeder is adjusted by a hydraulic system which enables the track feeder to float on the scrap and exert a predetermined yet variable force, to raise or lower under command, or to remain in a fixed position. The shredder has a cutter bar with four cutting edges so that when one is no longer effective the bar can be turned to place another cutting edge opposite the paths of the hammers in the shredder. Also, the cutter bar is adjustable toward and away from the hammer paths to maintain optimum spacing. In addition, the bar can be moved longitudinally so that grooves worn in it are moved out of alignment with the hammer paths.
