Abstract: A printing machine with preferably several inking units, which are disposed on a common back-pressure cylinder (12), with in each case at least one roll body (16, 18), which is held with its two opposite ends in two bearing blocks (22, 24) that can be moved approximately radially with respect to the back-pressure cylinder, and is held with its one end in a hinged bearing (42), fastened to the bearing block (22) there, while it is clamped with its other end in a cantilever manner in a holding device (26), it being possible to move the holding device and the hinged bearing in such a manner relative to one another that, after the hinged bearing is lifted up, the roll body can be moved out of this bearing and then removed in an axial direction, characterized in that the hinged bearing (42), in the lifted-up state, is open in the direction of movement of the associated bearing block (22) and, by moving this bearing block in the direction approximately radial to the back-pressure cylinder (12), can be moved into th

Abstract: A bag includes two parallel walls, each with two side edges each; a bottom connected with lower ends of the two walls and which can be folded in a plane of the walls; and two carrying handles, which in each case have two parallel legs and one cross member connecting the two parallel legs and are fastened with fastening sections, formed at their legs, in each case to one of the walls of the bag and are folded back on themselves at fold lines, so that they do not protrude beyond the walls and are detachably fixed to the bag, the cross members of the two carrying handles being offset from each other in the folded-back position by an amount, which corresponds at least to the width of the cross members and the fold lines of the two carrying handles being mutually offset by about half this amount, and the carrying handles being mutually offset in a direction perpendicular to the side edges to such an extent, that the parallel legs of the two handles do not overlap one another.

Abstract: A flexographic printing press with one or several color printing units (12), which are disposed at the periphery of a common back pressure cylinder (10) and, in each case, have an impression cylinder (14; 14') and an applicator roll (16) and the impression cylinder of which can be driven independently of the back pressure cylinder, characterized in that each applicator roll (16) can be driven over a gear assembly (32, 40; 32') with a fixed transmission ratio by a central wheel (24) fixed on the shaft (22) of the back pressure cylinder (10).

Abstract: Apparatus for changing printing cylinder sleeves in printing machines, includes two bearing blocks which serve for the rotatable support of the printing cylinder sleeve during the operation of the printing machine, a shaft running axially through the printing cylinder sleeve, and a lifter disposed at one end of the shaft outside of the corresponding bearing block, by which the shaft can be clutched and can be raised together with the printing cylinder sleeve freely cantilevered, so that the printing cylinder sleeve comes free of the bearing blocks and can be withdrawn axially from the shaft, and the printing cylinder sleeve is provided with hollow journals at both its ends, which are mounted in the bearing blocks during operation of the printing machine.

Abstract: A method for manufacturing bags (18) with strap shaped handles (16) which provides for the handles to be bonded to the outside faces of the bags by attachment portions (24) at the free ends of their parallel legs, in which assembling and bonding of the handles (16) is effected during continuous transport of the bags (18), with their bottoms (20) forward, from a bag making machine (10) in which the bags without handles are produced, to a stacker station; the handles are folded such that their portions (26) protruding beyond the bag marginal edge while in the usage position are folded over forwardly as viewed in bag transport direction; and the handle portions (26) as folded over are detachably tacked to the bags (18) and/or the attachment portions (24) before the bags are entering the stacker station (14).

Abstract: In a printing press having a chamber body, a doctor blade clamping assembly includes a leaf spring having a plurality of leaves assembled together in overlying relation to each other, the leaves being of different lengths; bolts extending through the leaf spring and secured to the chamber body, the bolts engaging the leaf spring to secure the leaf spring to the chamber body in at least partial overlying relation to a doctor blade such that the leaf spring applies a biasing force to the doctor blade to clamp the doctor blade to the chamber body; an inflatable bladder positioned in a recessed area in the chamber body and at least indirectly engaging the leaf spring when the bladder is inflated so as to bias the leaf spring in a direction away from the doctor blade to release the doctor blade from the biasing force of the leaf spring; a conduit connected with the bladder; a spacer positioned in the recessed area between the bladder and the leaf spring; a bladder control connected with the conduit, the bladder co
