Abstract: This invention relates to a method of fixing an end of a coiled wire on a take up spool and an apparatus therefor.When the wire is wound on the take up spool, an initiating end of the wire is caught by a catching pawl such as a snagger on a catching plate (snagger plate) which integrally rotates together with the take up spool and thereafter it is wound on the take up spool. Before or immediately before wire winding on the take up spool ends, a wire introduction cover advances to cover the filled take up spool. At that time, a terminating end of the wire on the filled take up spool is so led as to run along the inner surface of the wire introduction cover and come close to the catching plate. Wire drawing lever means on a wire drawing plate draws up the terminating end of the coiled wire to catch it on the catching pawl so that the initiating and terminating ends of the coiled wire intersect on the catching plate.

Abstract: Snarls are formed at winding machines and the like when the thread tension is reduced. By reducing the angle .alpha. which the thread forms with the end surface or face of the delivery bobbin or spool the friction between the thread and the bobbin edge can be increased to such an extent that no thread coils or turns can disengage from the surface of the delivery bobbin and become snarled even when the thread tension decreases. The reduction in the angle .alpha. may be achieved by lowering a thread guide eye towards the delivery bobbin, by lifting the delivery bobbin or by deflecting the thread at an extension or protection provided at the bobbin. Upon deflecting the thread at the extension a thread reserve can be provided by applying thread turns at the extension in a direction opposite to the thread turns wound on the bobbin and which thread reserve can be eliminated in a simple manner by withdrawing the same as a whole or in sections.

Abstract: An apparatus which can store successive sheets of a stream of sheets between the convolutions of bands which are wound onto successive cores has a transporting unit defining for the sheets an elongated path, and a pair of feed screws which are disposed above and extend longitudinally of the path and serve to simultaneously support a core as well as a fully grown roll including a core, a band which is convoluted therearound and a supply of sheets which are confined between the convolutions of the band. The feed screws can be rotated to move the core and/or the roll thereon lengthwise of the path through a distance which at least matches the radius of a core plus the radius of a roll. A lever which is indexible through angles of 180 degrees is mounted below the path and carries a full reel and an expiring or empty reel for the band.

Abstract: In a tape transport mechanism, a payout reel is supported on a shaft whereabout is wound a helical spring inertia brake fixed at a first end and free at a second end, wound such that rotation of the payout reel in response the drawing therefrom of ribbon tends to cause the helical spring inertia brake to be wound more tightly onto the shaft. A portion of the ribbon passes onto a tension arm. A projection on the tension arm engages the second free end and unwinds the helical spring inertia brake to allow rotation of the shaft opposed by a predetermined amount of torque to maintain tension in the moving ribbon. When the moving ribbon ceases to be drawn from the payout reel, the tension arm moves back for the projection to allow the helical spring inertia brake once more to grip the shaft and bring the payout reel rapidly to a halt.
