摘要： A method for slitting a continuously running magnetic tape having a magnetic layer formed on the surface of a non-magnetic substance without producing burring. The tape is slit from the front and rear side surfaces of the magnetic tape by a pair of upper and lower rotary blades having rotational axes substantially parallel to the tape surface and extending in the tape width direction and radially overlapping each other. A gap is formed between blade edges of the rotary blades in the tape width direction having a width in a range of 3% to 20% of the thickness of the magnetic tape.

摘要： The present invention relates to a shear for shearing laminar elements, flat material. This shear comprises at least one pair of blade-holders and associated blades which move substantially parallel to each other along straight lines which are spaced apart a predetermined distance from each other. The predetermined distance is computed as a function of the thickness of the material and the nature of the material which is to be sheared. The blades have cutting edges which, at the time of shearing, apply a pair of mutually perpendicular forces Fx and Fy to the material being sheared. The force Fy acts along a straight line perpendicular to a plane or surface through the material or upon which the material rests. It is along the straight line of the force Fy that the blade-holders and blades move during the shearing operation.

摘要： A method of accurately punching holes into a moving web of a thermoplastic film material, and more particularly, punching holes into the web through the intermediary of a rotary serrated tube punch. The invention relates to accurately punching holes into an advancing web of thermoplastic film material utilizing a novel rotary serrated tube punch. The film web is continuously advanced over at least a portion of the circumferential surface of a rotatable anvil roll, and tensioned against the anvil roll surface through the use of suitable tensioning devices, such as tension rollers arranged upstream and downstream of the anvil roll. At least one opening is formed in the circumferential surface of the anvil roll which is smaller than the size of the hole which is desired to be punched into the film web through the use of the inventive rotary tube punching arrangement. An annular groove extends about the hole in the surface of the anvil roll, forming a land between the hole and the groove. The rotary tube punch possesses a serrated cutting edge at its radially outermost end, and is adapted to be rotated in synchronism with the anvil roll so as to cause the serrated cutting edge pierce through the web in a precisely aligned position with the groove in the rotating anvil roll, with the film web being supported on the land about the hole and on the anvil roll surface externally of the punch, and to thereby produce an accurately dimensioned hole in the moving web without the necessity for stopping the web. The anvil roll may be constructed hollow, and communicates with a suctioning source for aspirating punched out film material segments.

摘要： A punch ring apparatus particularly useful in a printing operating involving web fed paper is provided which is easily adapted for punching file holes, line holes, or a wide variety of hole patterns in the moving paper web, thereby substantially reducing makeready times and associated costs. The punch ring hereof preferably includes a plurality of radially-oriented, spaced-apart punches mounted in the punch ring and radially shiftable between an outermost punch position and a retracted position, with the punches being spring biased into the retracted position. The punch ring preferably includes an annular concentric groove in an axial face thereof, with the proximal ends of the punches extending into the groove when the punches are in the retracted position. One or more annular camming rings are received in the groove and configured such that axial rotation of a camming ring will outwardly shift one or more of the punches into the punch position to produce the desired hole punch pattern. Complementally, the die ring of the present invention is configured for operation with any of the hole punch patterns selectable on the punch ring. Thus, the operator can quickly and easily reconfigure the punch ring apparatus hereof for a different hole punch pattern in a minimum amount of makeready time.

摘要： An apparatus for continuously cutting thin trim strips from a moving printed web so as to form uniform web products and removing the trim strips from the cutting area is provided, for in-line operation with a web press. The gapping of the web is effected by a cutting cylinder with a hollow bore, which carries at least two pairs of spaced cutting knives that act against a stationary shear blade. The space between each pair of blades connects with the cylinder bore, which in turn is connected to a low-pressure source. As a printed web is fed to the cutting cylinder, the spaced knives cut trim strips in the web and these strips are removed through the space and the cylinder bore by air flow caused by the low-pressure source. The circumferential speed of the knives acting on the web is greater than the speed of the web itself, this reducing any bubbling of the web, and the width of the space between knives is greater than the width of the trim strip. This system enables removal of trim strips down to a width in the range of 1/16".

摘要： A mechanism for cutting a web of flexible sheet material which is adapted to be used in a dispenser having a feed roller and a pinch roller between which rollers the web passes. A knife is pivotally mounted in the feed roller to swing about an axis laterally displaced from the plane of a radially outward portion of the knife defining a cutting edge which edge is projected outwardly beyond the periphery of the feed roller to cut the web as it passes over the feed roller and cam followers ar carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.

摘要： An "easy open" feature for a sealed flexible pouch and method and apparatus for accurately positioning said feature in the sealed border region of said flexible pouch. The feature comprises a stress concentrating aperture exhibiting a strong tendency to initiate a directional tear while maintaining integrity of the sealed pouch until an opening force is applied. In a preferred embodiment the pouches are cut from a moving web by a rotary shear cutter while a web punching means operatively connected with each cutter blade is engaged in the moving web. Because the web undergoes no movement relative to the cutting means or the punching means until both operations have been completed, the aperture is precisely positioned with respect to the severed edge of the pouch. In a particularly preferred embodiment, the sealed edge of the pouch is subjected to a high level of tension and is unsupported in the area of contact with the punching means during the aperturing operation. This concentrates the stress applied by the punching means and helps to form an aperture in the seal, even where tough and/or stretchy pouch materials which are prone to stretch and deform rather than rupture are employed. While the precise shape of the aperture is not critical, it is preferably non-circular in order to provide at least one area of stress concentration within the aperture and thereby facilitate tearing at relatively low levels of applied stress.
