Abstract: In an apparatus for separating flattened valved sacks which are reeled in an overlapping formation, the reel is turned by endless belts pressing on the reel periphery as the overlapping sacks are being taken off the reel. A roller presses the overlapping sack formation onto the belts and this roller is disposed at a spacing of no more than about one sack length from the point where the sacks leave the reel.

Abstract: An apparatus for storing flat articles comprises a first conveyor, two deflectors for diverting the articles fro the first conveyor to a second slower conveyor disposed beneath each deflector at right-angles to the first conveyor for receiving the articles in an overlapping formation, a frame adjoining the second conveyor and carrying rollers at each end, endless driven conveyor belts passing over the rollers, the frame being pivotable about the axis of one of the rollers so that the other roller is disposed adjacent to a winding for receiving covolutions of the overlapping formation of articles and so that the belts are in contact with the convolutions to turn the core, and a supply reel of holding tape associated with each winding core.

Abstract: The invention relates to apparatus for spreading open cross-bottoms on conveyed tubular members which are to be further processed to form bags or sacks, the apparatus having two spreader members which rotate sunchronously and symmetrically relative to the plane of the tube ends to be formed and which are driven by way of a non-uniformity drive transmission and which engage into the tube ends for spreading thereof, the degree of non-uniformity of the drive movement produced by the non-uniformity drive transmission and the phase position of the non-uniformity thereof being adjustable.
