Abstract: An economical liquid metering device which dispenses liquid in digital steps. Further advantages are: the ease of liquid change because components which are in contact with the liquid are economically exchangeable or disposable, and each computer pulse dispenses a predictable quantity of the liquid. To provide a continuous flow, the volume and operation rate between pump pulses may be controlled, so that the dispensing rate becomes substantially continuous.

Abstract: A economical liquid metering device which dispenses in a digital steps the supply of liquid provided to predetermined circumferential stripes on a rotating surface. Further advantages are: the ease of liquid change because the entire mechanism which is in contact with the liquid, is exchangeable; the liquid is protected from drying and contamination; the liquid remaining at the end of a run, may be safely reused at a later time; the liquid is dispensed in digitally predictable quantities, may be reused at a later time, and each computer pulse dispenses a predictable quantity of the liquid. To provide a continuous flow, the volume and operation rate between pump pulses may be controlled, so that the dispensing rate becomes substantially continuous.

Abstract: An improved web splicing apparatus that permits better handling of rolls of paper and other materials and the automatic splicing of the beginning of one roll of paper onto the approximate end of a second roll of paper without discontinuing the flow of paper to the utilizing device and without the use of core shafts. The apparatus utilizes two opposed pairs of independently controlled and positioned web roll support arms which are pivoted about spaced shafts and rotatably support cores of the paper rolls. This invention also allows sequential splicing of rolls having unequal web widths. This configuration also allows the right and left roll support arms to move the rolls upward in an overlapping path from a single loading position, thus providing a machine having considerably reduced dimensions and floor-space requirements. Another aspect of this invention is the automatic ejection of depleted roll-cores.

Abstract: A joining system for flat end discs is used in an elongated encased food product. The food casing is joined to the flat end discs permitting food stuffing of the casing. An adhesive joining, a clamping joining, a tension band joining or a piercing joining takes place in an area external to and within the peripheral boundaries of the flat end discs. The axial outward force of the food product on the discs is thus coupled to the axial tension of the casing joined to the discs.

Abstract: An offset printing machine that has an eccentrically mounted blanket cylinder operated by a single piston that moves the blanket cylinder from a first position separating the blanket cylinder from both the master cylinder and the impression cylinder to a second position engaging the blanket cylinder with the master cylinder for inking and to a third position engaging both the master cylinder and the impression cylinder for printing.

Abstract: A cylinder setting mechanism for an offset printing device in which a blanket cylinder moves eccentrically about a first pivot point to make contact with the master cylinder so that it can be inked and then subsequently moved eccentrically about a second pivot point to make contact with the impression cylinder to transfer the image to paper. The invention enables the first and second pivot points to be adjusted to compensate for wear, plate thickness, and paper stock. In addition, a stop is provided to insure that there is a predetermined contact pressure between the surfaces of the blanket cylinder and the master cylinder. The first eccentric adjustment is made by rotating an eccentric tube at only one end about a first pivot point. The blanket cylinder rotates about the outside of the eccentric tube. The second adjustment is made by rotating an eccentric shaft on which the eccentric tube is mounted to adjust the position of the blanket cylinder in relation to the impression cylinder.

Abstract: An improved plate clamping assembly for a duplicating machine which utilizes a pivoted or cantilevered beam in the leading edge plate clamp assembly and a calibrated cocking screw to enabling skewing of the plate on the plate cylinder by moving one end of the pivoted or cantilevered beam. The improved assembly also coordinates the leading and trailing edge assemblies during installation of the plate by automatically adjusting the trailing edge plate clamp assembly to accommodate for an adjustment in skewing of the leading edge of the plate by the leading edge clamp assembly. Finally, it utilizes spring assemblies to enable self-adjustment for different plate thicknesses.

Abstract: A cylinder setting mechanism for a single or multi-color offset printing device in which a blanket cylinder moves eccentrically about a first pivot point to make contact with a master cylinder so that it can be inked and then subsequently moved eccentrically about a second pivot point to make contact with the impression cylinder to transfer the image to paper. The invention enables the first and second pivot points to be adjusted to compensate for wear, plate thickness, and paper stock. In addition, a stop is provided to ensure that there is a predetermined contact pressure between the surfaces of the blanket cylinder and the master cylinder. The stop is automatically adjusted when the toggle is adjusted for a different thickness plate so that the desired offset printing pressure between the master and blanket cylinder surfaces is held at the optimum level.

Abstract: The method for cooling a hot web by passing it across a rotating thermally conductive chill roller having a circulating coolant therein. In accordance with this invention, one introduces as a coolant to the chill roller a liquid refrigerant at a temperature and pressure permitting the refrigerant to exist in liquid form, the temperature being also above the dew point of the ambient atmosphere. Likewise, the boiling point of the refrigerant at the desired temperature and pressure is low enough to cause heat to be absorbed by the chill roller substantially by vaporization of the liquid refrigerant. One then withdraws refrigerant vapor from the chill roller, and typically refrigerates it to reform the liquid phase for return to the chill roller. Typically, chlorofluorocarbon refrigerants are preferred.

Abstract: An apparatus is provided for handling a web of material fed from a roll. When the roll is larger than a selected amount, a roll contacting belt contacts the outer surface of the roll to aid in rotating the roll. The roll contacting belt is speed-responsive to a tension sensing means. Once the roll decreases to the selected amount, the roll contacting belt is disengaged from the roll and a core brake controls the speed of the roll. This arrangement reduces web upsets caused by out of round new large rolls and eliminates telescoping due to the action of the belt against small diameter rolls. In the illustrative form of the invention, the apparatus provides a continuous supply of web material by handling a first roll from which web material is being fed through an infeed roller and a nip roller, and a second roll from which web material is fed after the web material of the first roll has expired.

The roll contacting belt is speed-responsive to a tension sensing means. Once the roll decreases to the selected amount, the roll contacting belt is disengaged from the roll and a positive drive controls the speed of the roll. This arrangement reduces web upsets caused by out of round new large rolls and eliminates telescoping due to the action of the belt against small diameter rolls.

Abstract: An apparatus for providing a continuous supply of web material to a web printer or other system. The web material is fed from a first roll supported in a feed position, and when the first roll is near depletion, the leading end of a second roll is adhesively connected to the web of the first roll with that web then being severed. One belt drive means is employed for rotating both the forward and rearward rolls so that these achieve the same speed for the connecting and severing operations. The belt drive means are connected to the press drive through control means which vary the belt drive speed in accordance with the tension of the web. An indexing conveyor supports forward and rearward rolls to locate the rolls in the forward and rearward running positions and in intermediate positions for connecting and severing of the web material and for loading of new rolls into the system.
