A center shaft turret winder is provided with core change-over mechanism, so that rewinding of webs e.g. in a slitter-rewinder can proceed continuously, by replacing full cores with empty cores and severing the wound webs between the respective cores. The mechanism includes a knife member which pivots about an axis parallel to the center shaft axis to bring its cutting edge into contact with the moving webs, after the core shafts have rotated around the center shaft, so that the tension in the w...

A washing machine comprises a rotatable washing drum divided by an internal screw conveyor into a number of separate washing and rinsing zones. A chamber mounted on the external surface of the drum in the area of the principal washing zone communicates with the principal washing zone and contains a partition which defines a liquid-containing pocket. This pocket is at least partially filled with liquid throughout rotation of the drum and contains a heating device which acts to heat the liquid.

A packing machine for cigarettes comprises a carton blank reservoir, a carton blank hopper, a blank feeding device,a blank transfer conveyor, a bundle drum, a packet forming drum,a packet stacking unit and a packet orientation unit. Carton blanks are removed one at a time from the hopper by a suction device and fed intermittently by the transfer conveyor to a position adjacent a pocket in the packet forming drum, the blank then being pushed into the pocket so as to partially form it into a carto...

A haymaking machine has at least one rake member mounted for rotation about an upwardly extending axis. Tines or groups of tines are supported around the circumference of the rake member on corresponding means that enables the tines to move up and down with respect to a central portion, independently of other tines supported on adjacent means. In one version, groups of tines are supported at the ends of outwardly extending arms which are pivoted to the central portion. The tines can be mounted w...

A raking machine has preferably two rake heads that are rotatable about upwardly extending axes. Each rake head has an outer circumference defined by a generally circular flexible wall with raking means supported on the circumference of the wall. The wall can have stiffening members to reinforce the wall and to hold tines or tine groups that can be pivotally mounted adjacent the lower portion of the wall. Also, the wall can be supported from a central hub by flexible spokes or chains. Alternativ...

Wrappers of metallic foil are formed around groups of articles to be packed, in a machine which comprises a cigarette hopper, a cigarette bundle conveyor, a metallic foil feeding assembly, a foil conveyor, a cigarette compression device, a foil folding and tucking unit, a bundle transfer unit and a bundle orientation and ejection unit. Bundles of cigarettes are fed from the hopper into pockets on the bundle conveyor from which they are removed two at a time, at spaced locations, and pushed into ...

The present invention relates to method and apparatus for forming bundles of articles wrapped in a tubular wrapper including an upper panel having an upper flap at each end thereof, a bottom panel having a bottom flap at each end thereof, and a pair of opposed side panels, each having a side flap at the end thereof, and apparatus for forming an end closure at each end of the bundle, which includes a pair of folding wings for forming corner fold lines between the bottom flaps and their adjacent s...

A ranging arm shearer mining machine has sensing means for sensing the position of the rotational axis of a cutter drum mounted on the ranging arm relative to the pivotal axis of the arm.

A combined sorter and conveyor for articles of considerable bulk or weight, characterized by tandem sections articulated for movement between conveying position and discharge position; shock absorber means cushion the attainment of both positions but offer no resistance during initial movement from one position to the other.

A bending machine having one or more bending units wherein a former device is movable to clamp a workpiece so that the workpiece can be bent by a bending arm and tool moved arcuately about the former device, and wherein the movement of the former device is reversible to free the bent workpiece from the bending unit.
