Abstract: An apparatus for dispensing cushioning wrap material includes a box having a dispensing opening in communication with an interior of the box. A roll of interleaf material is rotatably positioned within the box such that a free end of the interleaf material can extend through the dispensing opening, and a roll of expandable sheet material in an unexpanded form is rotatably positioned within the box adjacent the first roll of sheet material such that a free end of the expandable sheet material can extend through the dispensing opening. A tensioning assembly is operably associated with the roll of expandable sheet material to control rotational resistance thereof. The interleaf material and the expandable sheet material can be concurrently pulled out of the box in abutting contact by a user and the rotational resistance of the roll of expandable sheet material causes the expandable sheet material to expand in thickness and length.

Abstract: There is provided a resistance generating device including a resistance generating unit disposed inside the rotation axis, the resistance generating unit having an inner ring and an outer ring, one of the inner ring and the outer ring being combined with the rotation axis and the other one of the inner ring and the outer ring being combined with the fixed part, the one being rotated with respect to the other one while generating a rotational resistance, and a switch part disposed inside a surface of the rotation axis.
Abstract: A method and device for installing synthetic turf uses a motorized turf rollout vehicle and a frame removably carried by the vehicle, the frame holding a roll of synthetic turf on a spindle at a first, forward end thereof. The roll and spindle are held in an orientation that is transverse to the first forward direction, and have a transverse dimension that extends beyond that of the vehicle. As the vehicle moves forward in the first direction, the vehicle engages and pulls the roll of turf, and the vehicle also moves on top of the just-unrolled portion of the turf. This accurately and efficiently places the turf on and over the base, in a desired position. Because the vehicle moves on top of the just unrolled section of turf, the present invention eliminates direct contact with, and disruption to, the underlying prepared base.
Abstract: The insert for roll paper products is pliable, preferably scent-impregnated, foam material that can be wrapped around a dispensing bar of a rolled paper dispenser, and resiliently grips the bar while adding friction to the total dispensing system. The dispensing bar and insert combination is then slid through the hollow core of a rolled paper product. The sleeve has dentate ends that extend beyond the ends of the paper roll. When the product core is rotated while paper is being dispensed, the passage of air through the dentate ends helps to dispense and distribute the scent through the environment proximate the paper dispenser. Moreover, the resilient foam insert provides friction between the paper roll and the foam structure, while also adding friction between the foam structure and the dispensing bar. This feature acts as a brake to prevent excess rollout of the rolled product when being dispensed.
Abstract: The present invention pertains to a trailer for lifting and transporting cable reels. The trailer has a base, a pair of substantially perpendicular cantilevers, and a latch assembly. The cantilevers lift a cable reel off of the ground, and the latch assembly transfers at least a portion of the weight of the reel from the cantilevers to the base. The base is mounted on wheels and can be pulled or pushed by a vehicle connected to the base.

Abstract: A method for assembly of a stay includes a series of steps that include connecting in the vicinity of an anchoring zone, a new group of N reinforcements to a shuttle located within the sheath of a stay to be installed. The shuttle is driven towards another anchoring zone by means of driving and guiding means. When the shuttle has arrived substantially in the vicinity of the anchoring zone, and as long as entangling is detected between the driving and guiding means in a portion contained substantially between the shuttle and the first anchoring zone, the shuttle is rotated about its main axis in the opposite direction to the said entangling. The group of N reinforcements is then separated from the shuttle. Each reinforcement of the group is tensioned between the anchoring zones. The preceding steps are repeated until the installation of the reinforcements is completed.
Abstract: An applicator for applying a rolled material to a body includes a spindle configured to hold the rolled material. A length of the spindle is at least equivalent to the width of the rolled material. A handle is coupled to the spindle, and a brake mechanism is integral with the handle for controlling a tension of the rolled material as it is applied to the body. The rolled material may be pre-wound on a spool that rotates around the spindle. Actuation of the braking mechanism increases pressure on the rotating spool in order to increase tension on the rolled material. Alternatively, the spindle rotates in conjunction with a shaft within the handle. The braking mechanism applies pressure against the rotating shaft to increase tension in the elongated material. Pre-wound cartridges of rolled material may be successively loaded on to the applicator's spindle for repeated usage of the applicator.

Abstract: A wire dispenser for dispensing coiled wire, such as welding wire, wherein the dispenser uses a wire guiding arm which rotates about the spool upper flange. The wire guide arm is mounted upon a vertical column supported by the spool end flange through a base plate concentrically located upon the spool flange. Selectively usable mounting structure defined on the base plate permits the dispenser to be used with spool end flanges having different sizes of hole dimensions and a cam type locking detent mounted upon the base plate firmly locks the base plate with respect to the spool flange. The wire guiding structure mounted upon the column includes a flexible tube permitting the wire guide to be most efficiently related to various sizes of wire coils and an adjustable arm supporting the flexible tube permits operators of ordinary skill to readily accommodate the dispenser to various sizes of spools.
Abstract: A method of processing an endless synthetic yarn is disclosed, wherein the yarn is withdrawn from a spinneret, and advanced into contact with a feed system which is operated under conditions which produce slippage between the feed system and the advancing yarn. As a result, a constant frictional force is exerted on the yarn irrespective of fluctuations of other parameters, and a precisely defined reduction of the yarn tension is achieved which facilitates the subsequent winding of the yarn into a package.
