    Abstract: An apparatus and method of converting a web of indefinite length into a plurality of web portions by slitting the web at a transverse point prior to processing the web portions into a plurality of use supply forms (such as rolls), wherein the plurality of web portions are separated by a two-stage process. A first stage of the process is a partial separation operation that almost entirely separates the web portions, but leaves the web portions connected, such as by a slitting operation that leaves a series of connected zones. The second stage includes the complete separation, such as by breaking of the connected zones. The complete separation of the web portions preferably occurs near the station at which the use supply forms are created, such as a winding station. Thus, the web portions, after substantial separation at the first stage can be handled (for example, guided and tensioned) as if the plurality of web portions were a full width web.

  • Publication number: 20040182213
    Abstract: A rotary die cutter for forming a non-linear line of perforations in a strip of material is disclosed. The rotary die cutter includes a rotatable anvil roll and a rotatable knife roll. The knife roll has a peripheral surface with at least one knife formed thereon. The knife has a non-linear configuration. The knife extends across at least about half of the width of the knife roll and has a plurality of land areas each separated by a notch. The knife roll is coaxially aligned with the anvil roll to form a nip therebetween through which the strip of material can pass. For each rotation of the die cutter, the knife will pass through the strip of material and be brought into direct contact with the anvil roll and form a non-linear line of perforations in the strip of material.

  • Patent number: 6766722
    Abstract: A cutting and transport roller and a process for cutting the material webs which rest on the peripheral surface of the cutting and transport roller. In so doing, the material webs are severed with the aid of a cutter, which is located inside the shell of the cutting and transport roller in its resting position and which exhibits at least one knife, which during the cutting process of the material web reaches through an opening in the shell of the cutting and transport roller. The cutting motion, which is executed by the cutting surfaces of the knife during the cutting process, exhibits rotary components, whereby the rotational motions of the knife run about an axis of rotation, which is either parallel or at an acute angle to a perpendicular line on the plane which is defined by the radial (r) and axial (z) coordinates of the cutting and transport roller.

  • Patent number: 6718855
    Abstract: A rotary die cutter for cutting a series of irregular-shaped blanks from a continuous web. The rotary die cutter includes a male die cylinder that has a series of die cavities formed along its outer circumference. Each of the die cavities includes a surrounding cutting edge that defines the shape of the blank to be cut. The male die cylinder is pressed into engagement with either an anvil cylinder or a female die cylinder to form either crush-cutting or shear-cutting nips therebetween. The continuous web is fed into the cutting nip such that the cutting edges of the die cavities contact the web to cut the blanks from the web. A plurality of vacuum ports positioned in the die cavities along the outer circumference of the male die cylinder are connected to a source of vacuum contained in the male die cylinder to remove the die-cut blanks from the web. The die-cut blanks are vacuum-transferred to a stacking unit, while the scrap web is continuously discarded by air-conveying removal.

  • Publication number: 20030106402
    Abstract: This invention provides patterned tread strips of uniform shape and dimension from salvaged tire carcass tread strips adapted for producing products requiring stacked layers of tread strips. Novel methods of and apparatus for shaping the tread strips in one embodiment results in trimming edges of substantially rectangular shaped tread strips salvaged from tire carcasses having two shorter ends and two longer sides to produce precisely uniform width between the longer sides. Thus the longitudinal tread strips may be passed from one end longitudinally through a power actuated strip feeder which establishes slicing means operable at designated spacings near opposite edges of the tread strips to cut away edges and produce uniform longitudinal strip widths between said two shorter ends as the strips pass through the strip feeder. Other shaping embodiments of the invention include tread surface shavers for producing strips of precise thickness, and length cutters to provide specified lengths.

    Abstract: There is disclosed a cut line forming method including: using a cutter roll (1) having cutting blades (2) protruded on its outer circumference and an anvil roll (10) for receiving the cutting blades; feeding a sheet (20) into the clearance between the cutter roll and the anvil roll; and turning the rolls individually to form cut lines (21) in the sheet. The cutting blades (2) of the cutter roll (10) are formed into a shape of letter “V”. The anvil roll has receiving faces (11) of a predetermined width (w) formed at an interval in a roll axis direction. The cutter roll (1) is turned to direct the crests of the V-shape of the cutting blades forward of the turning direction thereby to advance cuts from the side of the crests of the V-shape so that cut lines corresponding to the width size of the receiving faces may be intermittently formed in the sheet along the V-shape.

The inner cutting edge of each blade has a point located between the inner cutting edge and the stepped cutting edge. The heights of the points of the inner cutting edges are substantially equal for all blades. The heights of the points of the outer cutting edges are different among the blades. This hole cutter makes it possible to reduce anti-cutting resistance and obtain an optimal cutting state.
