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.

An expansion device includes an unexpanded slit sheet roll that is wound on a paper core that is longer than the width of the slit sheet paper roll. The paper core is placed onto a rod member. An adjustable downward pressure is exerted on the paper core and the paper core exerts pressure on the rod member. As the paper is pulled, the downward pressure creates the friction required to enable the unexpanded slit sheet to be unwind and fed while simultaneously expanding.

An improved method and apparatus for the interleaf winding of materials, especially adhesive, sticky, or tacky materials, which method involves maintaining a tension in the liner material at the point where it is mated with the material being wound.

A splice arrangement includes an unwinding arrangement for unwinding a finite first material web from a first material roll or a finite second material web from a second material roll, a braking arrangement for applying a braking force to the unwinding arrangement and/or the finite material web being unwound, a connection arrangement for connecting the finite material webs to form an endless material web, a storage trolley for the uninterrupted conveying of the endless material web, at least one material web tension-influencing device arranged before the storage trolley, and an actuation device, which is in signal connection with the at least one material web tension-influencing device for actuating the same.

A watercraft lift with hydraulically actuated arms which self-installs a fitted three-dimensional watercraft cover on a powerboat. A mechanism enables a linear actuator to drive a swing arm up to 180 degrees. The upper end of a two part arm articulates mechanically as the arm moves to reduce vertical elevation while operating. A spring-tensioned elongated roller keeps the cover tight and self-rolls the cover on the elongated roller when the actuated arms are pivoted forward. The mechanism can be attached to the guides of most watercraft lifts.

A substrate conveying device and a deposition apparatus are provided. The substrate conveying device includes a transmission shaft, a plurality of conveying rollers, and a plurality of bearings. The conveying rollers are configured to convey a substrate respectively. Each conveying roller is assembled to the transmission shaft via the corresponding bearing. Each bearing includes a stator and a rotator. Each conveying roller is fixed to the corresponding rotator. The stators are fixed to the transmission shaft. A magnetic repulsion force parallel to an axial direction of the transmission shaft exists between the stator and the rotator. The stator drives the rotator to rotate via a friction force generated by the magnetic repulsion force between the stator and the rotator.

A conveying apparatus includes: a conveyor configured to convey a web while unwinding the web from a web roll; a brake configured to apply brakes to rotation of the web roll; and a controller configured to perform control to unwind the web from the web roll and convey the web with the conveyor while giving tension to the web by applying brakes to the rotation of the web roll using torque of the brake. The controller is configured to determine the torque of the brake during deceleration of the web to be a value depending on an inertial load of the web roll.
