A tape dispenser having a handle, a base plate disposed at an end of the handle, a rotatable tape mount engaged on the base plate, a nose member disposed on the base plate, a cylinder rotatably engaged on the nose member near a cutter and a guide element is provided. The guide member is slidingly engaged on the base plate. The guide element is adjustable between a loading position which is slid rearward ly to provide space between a tape engaging end of the guide element and the nose member and a loaded position where the end of the guide element is located adjacent the nose member. A tape core support assembly can include a shaft secured to the frame and an axle assembly disposed about at least a portion of the shaft. The axle assembly includes a hub having an outer surface and at least three arcuate arms extending outwardly from the hub outer surface. An outer periphery of the arms forms a theoretical or actual cylinder configured to receive the tape core. The rotatable tape core support can include a stationary axle, a spring inclusive bushing mounted to said axle, and a rotatable tape mount. The rotatable tape mount can include a housing that receives the bushing such that the spring engages a surface of the housing to control rotation of the tape mount.

A printing system includes a transport path for transporting a web medium. The transport path includes a slack region wherein the web medium is slack or substantially tension-free. A take-up roller is positioned at a downstream end of the transport path for receiving and winding the web medium. A tensioning device is positioned along the transport path between the slack region and the take-up roller. The tensioning device includes a first surface arranged for exerting a friction force on the web medium moving over the first surface in a direction opposite to a transport direction of the transport path, such that the web medium is tensioned between the tensioning device and the take-up roller. Since the friction force tensions the web being wound onto the take-up roller, the wound media rolls are tightly wound when applying “loose winding.”

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 tension-inducing shaft system includes a shaft, two shaft caps, and a biasing mechanism. A bore extends through the shaft between two ends of the shaft. The shaft caps are positioned on the two ends of the shaft. Each shaft cap includes a collar having a size that is larger than the bore, a keyed end, and an anchor. The biasing mechanism is arranged inside the bore and is coupled to the anchors of the shaft caps so that the biasing mechanism exerts inward forces on the shaft cap. The keyed ends of the shaft caps can be coupled to a housing so that the shaft caps do not rotate with respect to the housing. The shaft is configured to rotate with respect to the shaft caps such that, when the keyed ends are coupled to the housing, the shaft is capable of rotating with respect to the housing.

A roll tensioner for use in maintaining a wrapping material cut edge of a wrapping material retained on a wrapping material roll located within a wrapping material box having an interior cavity with an interior front wall with a top cutting edge. The roll tensioner comprises a thin, flexible main body having distal and proximal end sections separated by a spring back reversion section, and formed having a first side and a second side. Attachment means, preferably an adhesive, is located on at least a portion of the proximal end section on the first side adapted to attach the proximal end section to the interior front wall of the wrapping material box. The spring back reversion section is composed of a material that has an immediate elastic response to a static load and is capable of substantially full recovery when the static load is removed. The distal end mechanically bends downward by way of the spring back reversion section in the interior cavity of the wrapping material box. The distal end section is adapted to rest against the wrapping material proximal to the wrapping material cut edge to retain the wrapping material cut edge in an upward, substantially parallel position to the interior front wall of the wrapping material box for easy grasping of the wrapping material cut edge by an end user.

An automated tissue section slicing, staining, and imaging system efficiently registers full-resolution tissue section images by applying scaled transformation matrices computed to register downsampled tissue section images to the full-resolution tissue section images.

A dispensing box with a roll tensioner houses a material roll and maintains a material cutting edge in an upward position for easy grasping during use. The roll tensioner comprises distal and proximal end sections with opposing bottom tabs separated by a spring back reversion section. A roll tensioner slide assembly integrated in the front wall of the dispensing box has opposing parallel slits terminating at opposing parallel slots with parallel locking flaps. Opposing bottom tabs of a roll tensioner are inserted through the parallel slots, resting in a first position during non-use and adapted to be slid down into a second position in the parallel slits when later engaged for use to retain the material cut edge in the upward position for easy grasping. The locking flaps have break-away top and bottom walls abutting a bend wall and are in a stored position and later opened outward to a locking position during use to prevent movement of the roll tensioner.

Disclosed is a device for mounting and unspooling a packaging film roll. The device is attached to a horizontal, form, fill, and seal packaging machine. The film is used to form the bottom portion of packages made by the machine. The device comprises of a shaft, sleeve subassembly, air chuck, adjuster subassembly, internal and external housing subassemblies, brake, and film roller subassembly. The sleeve subassembly along with the chuck is used for holding the packing film roll. The adjuster subassembly is used to aligning the packaging film roll with the machine's conveying chain. The conveying chain pulls the film into the machine, resulting in unspooling of the packaging film roll. The brake is used to controllably stop and restart the unspooling of the film roll, which allows the film roller subassembly to keep the packing film entering the machine is flat and properly tensioned.

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.

The current invention is generally directed to apparatuses and methods for controlling tension and tension disturbances in a web being continuously unwound from a roll of spirally wound web material. In accordance with the present disclosure, a rotary dancer mechanism is used for applying active and variable forces to a moving web in response to irregularities, such as variations in tension. In one aspect, the apparatus and method of the present disclosure may be used to attenuate undesired disturbances in the web as the web is being fed into a process.
