The present disclosure involves a belt drive mechanism which can be used to pay out or draw belt to or from a belt actuated system (or belt driven system). The mechanism features a self-winding spool which can automatically wind or unwind portions of the belt as they are withdrawn from, or fed to the belt actuated system. A second rotational axle (idler shaft), with one or more sheaves (e.g., pulley's or rollers) can be rotationally coupled to a capstan via a belt, and can be utilized to drive additional mechanisms in the belt drive mechanism, such as a winding mechanism.

A carrier tape holding device is installed in a component supply unit that supplies a component by drawing a carrier tape storing the component from a tape roll body formed by winding the carrier tape in a roll shape. The carrier tape holding device includes a storage portion that stores the tape roll body. The storage portion holds the tape roll body in a state where the component supply unit is able to draw the carrier tape from the tape roll body, and is capable of receiving a tape roll body for replenishment moved from a holder storing the tape roll body for replenishment in a state where the holder is detachably attached.

Cutting article, for example for cutting tape, that is removable from a container, such as a box, of tape. Wound tape articles containing the same. Kits containing the same.

A torsion spring used in a flexible display device includes a spring body having a first connection end configured to connect a reel of the flexible display device, and a second connection end configured to fix the torsion spring. An axial sectional area of the spring body near the first connection end is greater than an axial sectional area of the spring body away from the first connection end. When the reel rotates, the torsion force generated during the initial rotation of the reel is relatively large, and with the increase of the rotation turn number of the reel, the increase of the torsion force is relatively small.

A rewinding system includes a rewinding apparatus for winding a manufactured thin-film tape on a re-winding roll; a loading apparatus for loading the re-winding roll on which the thin-film tape is rewound; and a cutting apparatus for cutting the thin-film tape. The rewinding apparatus includes first and second mounting members in which re-winding rolls are inserted; and a connecting member connected to an end of each of the first and second mounting members to move the first and second mounting members. The first mounting member rotates around a shaft thereof, the second mounting member rotates around a shaft thereof, and the connecting member rotates the first and second mounting members to change positions of the first and second mounting members, and moves at least one of the first and second mounting members to the place where the loading apparatus is arranged.

The present invention relates in general to spool assemblies, and more specifically, to a tape take-up roller for collecting carrier strips, or tape, that attach a chain of bags for packaging food in a food production facility. A purpose of the invention is to provide an improved spool assembly that conveniently and safely allows an operator to collect and remove tape therefrom. In an exemplary embodiment, the spool assembly may comprise a series of cantilevered, elongated prongs having a closed first end secured to a base and an opposite open second end. The base may be rotatably coupled to a bearing housing that permits the base and series of prongs to rotate together around a longitudinal axis for collecting tape around the series of prongs. The spool assembly permits tape to be safely removed from the series of prongs by sliding the tape off the open second end without requiring the use of cutting tools.

A retractable reel system includes a reel, a gear assembly, a paddle wheel and a spring. The reel includes a concentric wheel shaft where the reel and wheel shaft rotate to wind and unwind a length of material from the reel. The gear assembly engages with an end of the wheel shaft to provide a gear reduction ratio between the wheel shaft and an output shaft of the gear assembly. The paddle wheel is connected to and concentric with the output shaft, and the paddle wheel includes a paddle that extends beyond an outer edge of the paddle wheel that rotates with the paddle wheel. The spring is arranged outside the outer edge of the paddle wheel. The spring is compressed by the paddle to store an energy when the reel is rotated to unwind the length of material from the reel. The stored energy is used to rotate the reel to wind the length of material around the reel.
