Abstract: A substantially ring-shaped or annular winding core serving for the reception of a package of products wound thereupon is frictionally mountable at its substantially cylindrical inner surface upon drivable support wheels and can be again lifted-off such drivable support wheels. At the inner surface of the mounted winding core there can be placed into operative position beneath the support wheels an essentially freely rotatable guide wheel. This freely rotatable guide wheel prevents lift-off of the winding core from the support wheels and can increase the friction which prevails therebetween. In order to be able to use winding cores having a purely cylindrical smooth inner surface and during the rotation thereof to nonetheless ensure for an exact positioning in axial direction, the guide wheel is deflectable in its operative position about a deflection axis which is radially directed with respect to the mounted winding core, which imparts to the rotating winding core an axial movement component, and an impact or stop arrangement is provided for limiting such axial movement.

Abstract: The baler comprises a bale case (1) extending fore-and-aft w.r.t. the intended direction of movement of the baler and having an inlet opening (55) in one side wall. A plunger (5) is mounted for reciprocation within the bale case and back-and-forth across the inlet opening for compressing successive charges of crop material to form a bale. A feeder duct (52) communicates at one end with the inlet opening in the bale case and curves forwardly and terminates in a forwardly facing open crop receiving mouth (50). The feeder duct comprises a pair of curved opposed walls (53,54) at least one of which is movable relative to the other. The at least one movable wall is movable relative to the other wall along its entire length, such that one cross sectional dimension of the feeder duct is variable along the length of the feeder duct from the crop receiving mouth. This ensures that, in use and as a charge of crop material is being accumulated in the feeder duct the opposed walls maintain contact with the crop material.

Abstract: A method and apparatus for roll forming to neck-in the open ends of drawn and ironed cans and replace double necks and triple necks is disclosed. An externally disposed free roll (11), preferably having independently rotatable sections is moved inward and axially against the outside wall of the open end of a rotating trimmed can to form a conical neck at the open end of the can, the two sections of the roller (11) being able to revolve at different speeds depending upon neck diameters respectively engag                              ed thereby. A spring-loaded interior support roller (19) moves under the forming force of the free roll (11). This is a single operation where the can rotates and the free roll rotates such that a smooth, conical necked end and flange are produced. At commencement of necking, the free roll (11) establishes a nip on the can wall in conjunction with an inner freely rotatably but axially immovable roll sleeve (24); coacting mating chamfer surfaces (11c, 24e) of the roll (11) and the roll sleeve (24) serve to generate a necking process which proceeds progressivley in the direction of the open end of the can, at the commencement of necking.
