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.

The scoring rules may be configured with scoring blades having selectively adjustable lengths and locations. The scoring rules may be constructed of a plurality of scoring segments that form the scoring blade. Each scoring segment is selectively movable between a scoring position and a non-scoring position for creating customizable score line lengths and locations.

There the double layer of sheeting is separated, with one layer being fed to the drive roll of the top assembly, and other layer proceeding through the other compression rolls of the middle assembly. Completed covers exiting from the superimposed assemblies are collated and transferred by transport and collating belts to a transversely adjustable ejection mechanism where the covers are ejected from the device.

Since pairs of cutters are provided within the rollers and since guide plates are provided around the rollers, the material is held abutting the rollers even when the material is cut by the cutters. The material is then conveyed within a reducing drum. The pitch of the corrugated portions formed on the material is reduced and the material is formed into a semicircular shape within the reducing drum. After passed the reducing drum, the material is transferred to a forming path.

Abstract: When blanks for producing (cigarette) packs are made in the region of the packaging machine itself, especially by being severed from a web of material (12), the blank production must be matched to the performance of the packaging machine. For severing blanks (10, 11) from a web of material (12) having stampings, perforations, etc. drawing rollers (25, 26) and conveying rollers (33, 34), on the one hand, and tearing rollers (27, 28 and 35, 36) running at a higher speed, on the other hand are used.

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.

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.

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).

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.

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.
