摘要： The rear cross rod that supports the carrier rods insertable in grooves in a stacking table for continuing the lifting of a residual stack while the table is lowered for loading a fresh stack without interrupting operations from the top of the residual stack, supports the cross rods from hanging collar brackets on its underside so that the rear cross rod has its body above the carrier rod and is adjustable along the length of the carrier rod and can function as an effective rear stack stop to stabilize the stack position. In one embodiment the rear cross rod is fixed in its position for a particular stack size by clamping sliding brackets on lateral rods that run from the respective ends of the front cross rods back to an extremity at which the rear chains of the hoist are connected. In another embodiment the rear cross rod is suspended directly by the rear hoist chains that run over pulleys which are adjusted horizontally to position the rear cross rod, while a scissors mount held on the rear support pillars of the frame of the sheet-feeding mechanism is provided that may be clamped in position to prevent rearward swinging of the rear cross rod once it has been moved into position. The pulley system in this case makes possible horizontal adjustment of the rear cross rod without change of the level at which it is suspended.

摘要： An arrangement for forming a sequence of underlapping sheets when conveying sheets that are cut off a paper web by a sheeter located in front thereof, to the feed table of a machine working the sheets. Suction equipment is located above the sheet web in the area between two draw-off equipments which are driven at different feed rates. A lifting device is located below the sheet web to bring the rear zone of every sheet into action with the suction equipment, so as to form a guide gap for the following sheet. The suction equipment is provided with a suction box connected to a vacuum supply that may be adjusted stationary during operation. The suction box has at the bottom a punched plate which is provided with a width corresponding to the maximum workable sheet width.

摘要： A sheet delivery device is provided that allows for high output and accurate operation during changing of the main stack. The device includes two secondary stack carriers which are normally disposed on opposite sides of the main stack in a first lateral waiting position. The secondary stack carriers are reciprocally moveable between the first lateral waiting position and an operative position. In the operative position, the secondary stack carriers accumulate a secondary stack while the main stack is being changed. This secondary stack is later deposited on the new main stack. Cooperating with the secondary stack carriers are separating elements normally disposed above the secondary stack carriers in a second lateral waiting position. The separating elements are reciprocally moveable between the second lateral waiting position and a separating position. In the separating position, the elements accumulate a temporary stack to form an entry gap above the main stack. The secondary stack carriers, which are plate-like enter this entry gap to arrive at the operating position. The separating elements thereafter deposit the temporary stack on the secondary stack carriers to form the secondary stack.

摘要： In the case of an apparatus for forming a stack of sheets comprising a brake means placed at (in terms of sheet motion) the leading edge of the stack and downstream from a sheet transport means, the brake means having at least one brake roller driven at a lower peripheral speed than the speed of transport of the sheets and a timed sheet nip member adapted to engage a sheet and move it towards the brake roller, one aim of the invention is to ensure reliable retardation and straightening of the sheets without damage to them. In order to attain this objective the brake means, whose sheet nip member or members is in the form of at least one segment able to be driven at a speed equal to the speed of the braking roller cooperating therewith when tripped by the sheet, is placed at the downstream end of at least one suction belt designed to receive the respective sheets from a sheet processing machine, and at least one blow tube is placed over the stack and downstream from the said brake roller, such blow tube, that is supplied with air under pressure, having at least one nozzle generally directed in the direction of sheet transport.

摘要： The present specification discloses an apparatus for washing a rubber blanket cylinder of a printing machine. The apparatus comprises a cleaning cloth which extends between a supply roll and a take-up roll, with control and drive means adapted to rotate the take-up roll in a step-wise manner to thus take up uniform lengths of cleaning cloth. A rotatable guide roller is arranged to press the cleaning cloth between said rolls, against the rubber blanket cylinder, the rotatatable guide roller having a resiliently deformable outer surface across which the cleaning cloth is guided. A reversible brush roller is located upstream of the rotatable guide roller in the direction of rotation of the rubber blanket cylinder, and is in contact with said cylinder, and a cleaning agent supply and a water supply are arranged to feed said brush roller. Said control and drive means comprises a crank which acts upon a lever via a connecting rod, said lever being connected to a take-up shaft, in which the take-up roll is mounted, by way of a one-way clutch. The point at which the connecting rod acts upon said lever is variable dependent upon the quantity of cleaning cloth taken up by said take-up roll. The width of the cleaning cloth corresponds only to a portion of the length of the cylinder, and guide and operating means are provided for moving the apparatus transversely along the entire length of the cylinder.

摘要： An arrangement for metering a blast of air delivered to a driven machine, particularly a sheet separation device of a sheet feeder. A control slide is connected via an air intake opening to a pressure source, and the control slide has an air discharge opening connected to the driven machine and leading into the open. The latter opening is controlled or disconnected during upward movement or stoppage of the machine coupled to the driven machine by means of a control element actuated as a function of the machine speed. The air intake opening and the air discharge opening leading to the driven machine, face each other coaxially, and upon reaching a set final speed, these openings are connectable by means of a coaxial recess passing through the control element. A rotary valve plug with a through-bore is provided to form the control element. The air discharge opening leads to the outside and is located offset relative to the air intake opening in the valve plug direction of rotation corresponding to a speed reduction. The through-bore of the valve plug in this region has an oppositely-directed expansion corresponding to the amount of offset. The valve plug is connected by a crank arm mounted on a bearing trunnion, and this crank arm is connected to a servomotor operating as a function of the machine speed.
