摘要： Provided are a method and an apparatus for manufacturing a fiber-reinforced resin molding material by which, when the fiber-reinforced resin molding material is manufactured, separated fiber bundles can be supplied to a cutting machine in stable condition while avoiding the influence of meandering of the fiber bundles or slanting or meandering of filaments occurring in the fiber bundles. A method for manufacturing a sheet-shaped fiber-reinforced resin molding material in which spaces between filaments of cut-out fiber bundles (CF) are impregnated with resin includes, so that a condition of the following expression (1) is satisfied, intermittently separating fibers of the continuous fiber bundles (CF) in a longitudinal direction by a rotational blade (18) serving as a fiber separating part and cutting out the fiber bundles with an interval therebetween in a longitudinal direction of a cutting machine (13A) to obtain the cut-out fiber bundles (CF). Expression (1): 1≤a/L (where a represents a length of a separated part of the continuous fiber bundles (CF) and L represents an interval when the fiber bundles (CF) are cut out in the longitudinal direction.)

摘要： A device for applying pieces to absorbent articles includes a supporting shaft rotating an axis; anvils rotating about the axis; a cutting unit operating with an anvil contact surface defining a cutting station for cutting a web into pieces; pads, each having a retaining surface for a piece, are moved about the axis for conveying a piece from the cutting station to a releasing station for release onto a substrate. Each pad rotates for varying the orientation from the cutting station, where the larger side of the pad is parallel to a feed of the web, to the releasing station, where the larger side of the pad is transversal to the feed of the receiving substrate, and vice versa. Each pad translates parallel to the pad axis, away from and towards the shaft axis. Each pad has an oscillating movement about its own axis.

摘要： A tape dispenser has a cutter or cutting blade that has at least two rows of teeth opposite each other relative to the cutter or cutting blade. The blade is to be installed on the tape dispenser in any of at least two orientations. By installing the blade in any of at least two orientations, at least one row of teeth will always project from the dispensing end to cut adhesive tape as it is unwound from a roll after being dispensed. This type of blade permits an easier manufacturing ability by reducing or eliminating the need to ensure proper alignment of the teeth to project outwardly from the tape dispenser housing.

摘要： A method for providing a nonlinear line of weakness on a web material includes: providing a counter component comprising a nonlinear shape, where the nonlinear shape has a shape width, W; providing a blade in operative relationship with the counter component and comprising a plurality of teeth; rotating at least one of the blade and the counter component into interacting relationship with the other of the blade and the counter component; feeding a web between the counter component and the blade such that while in interacting relationship the blade cooperates with the counter component to perforate the web, wherein the web is moving in a machine direction; and reciprocally shifting one of the counter component and the blade for a distance, D, in a shifting direction, wherein D is at least the translational distance that one tooth travels to cover the shape width, W.

摘要： A system for cutting a web material and applying the web material on a substrate. The system comprises a feed roll configured to advance a web material. The system includes an anvil roll configured to receive the web material from the feed roll and provide a section of web material having a defined length. The system includes a cutting element configured to cut the web material to form the section of web material. The anvil roll is configured such that the anvil roll surface advances at an anvil roll surface speed. The feed roll is configured to rotate at a first feed roll surface speed that is slower than the anvil roll surface speed and a second feed roll surface speed that is substantially the same as the anvil roll surface speed when the cutting element cuts the web material.

摘要： A feeding unit to feed a component in an automatic manufacturing machine; has: at least one holding head designed to receive and hold the component; a closed curved guide arranged in a fixed position along an application path; an equipment supporting the holding head and provided with at least one slide coupled to the guide by a plurality of wheels; a linear electric motor, and a movable slider electro-magnetically coupled to the stator and is rigidly connected to the slide. The guide has, on the surface in contact with the wheels, a first transverse profile having a concavity or a convexity; the wheels have, on the surface in contact with the guide, a second transverse profile, which has a convexity or a concavity, and generates, with the first profile, a shape coupling between the guide and the wheels, which forbids a transverse movement of the slide relative to the guide.
