A dispenser, apparatus, system and method for automatically dispensing portable or sterile items from a continuous length of packages of items ideally packaged as a stack, including a support shaped and configured to support the stack, a feed mechanism arranged in flow communication relative to the support for feeding the stack towards a dispensing point, a separation means extending from the feed mechanism, shaped and configured for separating an item from the stack at the dispensing point, an electric motor configured to drive the feed mechanism; and a sensor shaped and configured to detect a dispensing parameter, wherein in use, the dispenser is activated by a user providing the dispensing parameter to the sensor thereby activating the feed mechanism to automatically feed the stack towards the dispensing point such that the separation means separates the item from stack thereby allowing for the item to be dispensed.

An expansible chuck for holding hollow cylindrical cores used for winding and unwinding sheet material. A portion of the chuck body nearest the flange is stepped up so that the diameter of the chuck near the flange is slightly larger than the diameter of the rest of the chuck. The stepped up portion centers the chuck within the core which helps the expanding elements to uniformly grip the core.

In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.

A sheet supply device includes a supporter, a rotation device, a guide, a support shaft, a biasing member, a sensor, a roller, and control circuitry. The sensor is disposed to protrude from the facing portion toward the roll and biased in a direction to contact the outer peripheral surface of the roll. The sensor outputs a detection signal at a level corresponding to an amount at which the sensor protrudes from the facing portion. The roller is supported by the facing portion, to contact the outer peripheral surface of the roll at a position different from a position of the sensor in a circumferential direction of the roll. The control circuitry controls the rotation device based on a signal change rate that is a change amount of the level of the detection signal per unit time. The control circuitry causes the rotation device to rotate the spool in the winding direction, and stops an operation of the rotation device when the signal change rate based on a change in relative positions between the outer peripheral surface and the sensor without passage of a leading end of the sheet through the position of the sensor does not exceed a predetermined reverse set threshold value.

An apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, comprising an output device which is configured to eject at least one material web into the cutting region, wherein the output device comprises at least one driven feed roll and at least one counter-unit which forms a feed gap for the material web together with the feed roll.

A tape dispenser housing wound adhesive tape includes a brake spoke tapering (i.e., narrowing) from a distal radial end to a proximal radial end relative to a tape rotational axis, wherein the brake spoke effectuates the braking of wound adhesive tape on a hub by contacting the wound adhesive tape, the hub, or both simultaneously.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

An optical connector cleaning tool includes a cleaning tool main body, a feed-side bobbin, a cleaning head (cleaning portion), a winding-side bobbin, a moving body that moves at the time of cleaning, a feed mechanism that sends an unused cleaning medium in synchronism with the moving body, and a winding mechanism that drives the winding-side bobbin. The feed mechanism moves a turn-back portion at one point where the cleaning medium is turned back in a direction to separate from the winding-side bobbin. The winding mechanism includes a driving piece that engages with a rotation body of the winding-side bobbin. The driving piece slips with respect to the rotation body when a load to press engaging projections of the rotation body has reached a predetermined load.
