    Abstract: Using Zero Make Ready Bed Die Cutting, the top surface of the Cutting Plate/Platen/counter of a Flat Bed Die Cutting Machine is etched or engraved by laser or other method, to create a “female” channel. The channel should be sufficiently deep and wide, to accommodate the male cutting blades of the Cutting Forme being used. Cutting blade contact with the base of the channel, whilst not desirable, may occur due to reasons of machine age and/or wear or Operator ability or preference. The fundamentals of Zero Make-Ready remain unaffected. The Cutting Plate/Platen can be of a single or multi layered composition and should be affixed and registered at the same time that the cutting Forme is loaded and located. Using centre lines, locating pins, or any other method of registering the two, the female channel must register with and accommodate, the male cutting blades to affect a clean cut of the required design of die cut blank or shape.

  • Patent number: 4785696
    Abstract: A method and apparatus for presenting a serial succession of cut sheet portions to a work station. The sheet portions are cut from a continuous webbing which is processed by a cutting station and a web-breaking station. The cutting station partially severs the web downstream of its leading free end so as to define a first sheet portion between that free end and the point of cutting, with the first sheet portion connected to the web by one or more tab connectors. The webbing is then advanced downstream to the tab-breaking station where the tabs are broken to free the first sheet portion for independent movement further downstream. A vacuum belt engages the webbing, and particularly the downstream edge adjacent the partial severing, with a vacuum belt. The vacuum belt engages the webbing by bridging the partially-severed cut portion, so as not to interfere with the downstream tab-breaking apparatus.

  • Patent number: 4778165
    Abstract: In the apparatus for binding stacks (31) of zig-zag-folded layers (40) a folder (10) is followed by a stacking device (43), which has a lifting table (14). In stacking area (41) following folder (10) is provided a separating device (24) in the form of a rake with front separating heads (100), which can be provided with blast air nozzles. A straightening device (22a) is used for periodically compressing the folded edge (82a) and the folder is preceded by a cutting mechanism (110) for making cuts on the folded edges (82a) to be separated, so that the separating devices (24) are not required to operate at areas on the edges provided with conveying holes.

  • Patent number: 4758215
    Abstract: A photographic paper handling apparatus for handling a photographic paper in a continuous form having a plurality of images sequentially printed thereon in the longitudinal direction thereof is provided with a cutting-perforating section and a folding section. In the cutting-perforating section, the photographic paper which is transported along a photographic paper transport passage is cut into pieces each including a series of images printed in accordance with the order placed by each individual customer, and a perforation is provided in an area of each of the cut pieces of photographic paper which is defined between each pair of adjacent images. In the folding section, each of the cut and perforated pieces of photographic paper is folded along each perforation. Accordingly, it is possible to prevent prints processed in accordance with one order from being mixed with those in accordance with another order.

  • Patent number: 4708708
    Abstract: A method and apparatus are disclosed for skiving and hemming one or more edges of a paperboard web or blank to improve the sealing qualities of a container made from the paperboard. The paperboard is skived twice generally parallel to its edge, once to define an oblique surface and once to make a flat skived surface. The latter is folded over the former and heat-sealed to a heat sealable material adjacent the skived region, defining a wedge-shaped edge portion. The folded over part is preferably ironed to produce a substantially flat sheet, and the wedge-shaped edge is preferably reshaped at some point in the process to make the entire folded over surface substantially flush with the unskived surface to which it is sealed. The flat skived surface is preferably made by a milling procedure in which the milling teeth strike the material while moving in a direction opposite to that of the motion of the material.

  • Patent number: 4617850
    Abstract: A die-cutting machine comprises two form-carrying rolls (10,12) operable in timed relation to produce alternate blanks, with minimum wastage between the blanks, from a web fed at constant speed by a conventional feed mechanism (14). The rolls (10,12) are driven by computer-controlled variable speed high impulse duty D.C. motors (28,30) supplied with electrical power from thyristor controlled power supplies (36,38). Sensors (18, 24, 26) provide feedback signals representing web speed and instantaneous roll positions and speeds to the programmable computer units (32,34). The use of the computer-controlled D.C. motors avoids backlash problems in previously proposed mechanical drives and allows greater flexibility, especially in maintaining registration between the rolls and preprinted areas on the web. A flywheel arrangement is employed to reduce the loading on the motors during large variations in roll speed.

  • Patent number: 4608037
    Abstract: The invention relates to method and apparatus for removing the flaps from a perforated web of paper by drawing the perforated web over an abrasively surfaced drum rotating in the same direction as the paper is traveling and at a peripheral speed about seven times greater than the speed of the web. The web is passed over the drum such that the flaps are at the leading or downstream edges of the perforations and lie between the paper and the drum. A spring-biased pressure yoke holds the perforated web against the drum surface with a predetermined amount of pressure to facilitate abrading the flaps from the web.

Continuous strips of red and blue film are placed along preselected columns of eye cutouts. In accordance with a first embodiment, the eyeglass cutouts are separated from one another to provide one ply 3-D glasses. In accordance with a second embodiment, the sheet of material is folded to produce a single series of two ply eyeglass cutouts.

  • Patent number: 4388794
    Abstract: Apparatus for producing discrete blanks from a web of foil or the like is provided, in which the foil or the like are given continuous constrained guidance during the phase between separation of the web until transfer to a packet or packing machine. The web is transported into the system between a first pair of pulling rollers then transferred to a conveyor of two spaced belts. The belts are provided with a series of apertures through which a suction is pulled to hold the transported web. The belts diverge slightly and pull the web at a higher speed than the first pair of rollers so that the web is stretched both lengthwise and transversely. Severance from the web is carried out in at least one initial cut, followed by a main cut, during continuous constrained guidance.

  • Patent number: 4283185
    Abstract: Box blanks produced from a moving web by a paperboard corrugator are shingled on a stacker conveyor. The corrugator includes a shear which severs the web in response to a production run change signal into leading and trailing portions. A cut-off machine cuts the severed web portions into the box blanks. Box blanks cut from the leading portion of the severed web are part of the old production run. Box blanks cut from the trailing portion of the severed web are part of the new production run. The leading edge of the trailing portion of the severed web is tracked to the cut-off machine. The trailing edge of the first full size box blank of the new production run is detected at a first position relative to the stacker conveyor. The trailing edge of the first full size box blank is then tracked to a second position on the stacker conveyor. When the trailing edge of the first full size box blank reaches the second position, a command signal is generated.
