The present disclosure relates to a device and a process for cutting hollow fiber membranes having a large inner diameter.

A system and method for shaped cutting of washable sanitary absorbent articles having a back layer of washable fabric and the like is provided, wherein the back layer is fed longitudinally along a travel direction to a cutting unit including at least one cutting tool movable transversally to the travel direction so as to cut at least one longitudinal side edge of the back layer, in combination with a longitudinal displacement thereof, along a curved profile.

An underwater line cutting tool includes a cutter. The cutter includes a blade holder and a rotating manipulator arm. The blade holder includes two stationary arms in a V-shaped configuration including at least one blade attached to one of two stationary arms. The blade holder is attached to the rotating manipulator arm of a rotating manipulator that is attached to an underwater remotely operated vehicle.

An absorbent article processing device includes a cutter roll and an anvil roll. The cutter roll includes a roll main body; a blade protruding in a radial direction in a first angular range of a part of a circumferential direction of the roll main body; a first bearer protruding in the radial direction in a second angular range of a part of the circumferential direction including at least the first angular range and being in contact with the anvil roll, and being cut out in an angular range excluding the second angular range at a first end portion in an axial direction of the roll main body; and a second bearer provided around the entire circumference or a part of the circumferential direction and being in contact with the anvil roll at the second end portion in an axial direction of the roll main body.

This application relates to an amplifier selectively operable in first or second modes. The first mode is a BTL mode with first and second output drivers (103p, 103n) both active to generate respective driving signals that vary with an input signal. The second mode is an SE mode, where the first output driver (103p) is active to generate a driving signal at and the output of the second driver (103n) is held constant. A controller (201) selectively controls the mode based on an indication of output signal amplitude. In the first mode, a ratio of magnitude of the two driving signals varies with the indication of output signal amplitude, i.e. the magnitudes of the two driving signals may vary so as to be not equal.

A reveal edge tile cutting apparatus may have a tray with a top surface and a bottom surface, as well as a first set of tracks and a second set of tracks. Attached to these tracks is a vertical cutter featuring two cutting wheels, a horizontal cutter featuring a separate cutting wheel. A measuring device may be located on the top surface of the tray.

The cutting system is configured to cut a continuous strip which extends lengthwise in a longitudinal direction and widthwise between a first edge and a second edge into strips. The cutting system includes a drive device which imparts to the continuous strip a feed speed, a first cutting roller and a contrarotating second cutting roller that cooperate to cut the continuous strip across its full width. The first cutting roller is provided with a first helical blade and is driven in rotation A variable synchronizer makes it possible to select and to modify the synchronization ratio between the rotational speed of the first cutting roller and the non-zero forward speed of the continuous strip in such a way as to be able to adjust the cutting angle according to which the cross-section of the continuous strip is oriented with respect to the longitudinal direction of the continuous strip.

A food slicer for slicing a food item, and including a plurality of tracks, and weight slidable associated along the tracks for advancing the food item toward a blade. A weight guide can engage with the weight, with a follower slidable in a track channel defined along a longitudinal length of the tracks. The tracks can be attached to a hub to form a radial arrangement, with a frame slidable along the tracks. The weight guide can include a clamp arm having an opening releasably engageable with a protrusion extending from the weight, a locking arm having a latch engageable with a ledge of the weight, and a piercing arm having a piercing end configured to pierce into the food item. The weight can include a locking recess configured to receive the locking arm, and piercing sections extending having a piercing element configured to pierce into the food item.
