Abstract: Optical fiber must be adequately protected during manufacturing, testing, and transportation from physical damage due to over-bending, crushing, and chafing. Prior art methods of packaging optical fiber have been ineffective in protecting against these forms of damage and have required manual assembly, thus their effectiveness being heavily dependent upon operator skill and training. The present invention provides an optical fiber spool that has open and closed positions which allow optical fiber to be loaded into and unloaded from the spool automatically. Furthermore, this spool protects loaded optical fiber from physical damage such as over-bending, crushing, and chafing. The spool of the present invention achieves these goals by providing a plurality of cavities which open and close to capture the optical fiber. These cavities are formed between a plurality of radial tabs positioned around the circumference of a spool lid and over a channel formed within a spool base.

Abstract: The invention concerns a yarn bobbin with a rotationally symmetrical body the outside of which forms a surface which carries the yarn and which has a longitudinally protruding collar at one end. The aim of the invention is to design a bobbin of this kind which has the advantages of prior art bobbins but which, when wound, can be stacked with other, similar, bobbins without the yarn being damaged or snagged. The invention achieves this by virtue of the fact that the bobbin has, at its end with the yarn uptake, an additional collar which has the same external dimensions as the internal dimensions of the collar at the other end of the bobbin but is staggered radially inwards with respect to the yarn uptake, the collar being fitted with a yarn-reserve groove.

Abstract: An interconnecting structure for connectable tape stands formed with a plurality of resilient fingers extending axially from the free end of a hollow cylinder which extends from the inner face of a side wall, and the free ends of the resilient fingers being formed with radially outwardly facing flanges.

As a result, when the resilient fingers of one tape stand are inserted into the corresponding through holes on another tape stand, the flanges on the respective resilient fingers will enter the through holes and rest on the inner face of the side wall, thus to complete the interconnection of the tape stands. In addition, grooves are formed axially inwardly in the hollow cylinder on both sides of the resilient fingers for increasing the flexibility of the resilient fingers such that a tape roll is easy to replace.

Abstract: The winding body of the winding core has on its opposite ends projections, projecting in the direction of the longitudinal axis beyond the printing products wound up on the winding core, and recesses partially covered by the printing products. During the stacking of rolls one on top of the other in a tower-like manner, the projections of one winding core engage in the recesses of the winding core of the neighboring roll. During stacking, the wound up printing products of the rolls consequently come into contact with one another. Mutual slipping of the rolls during transport is thereby prevented.
