Abstract

The invention relates to an information accumulation technique and makes it possible to increase the reliability and durability of the tape by decreasing the value of the specific contact pressure in the zone of its exit from the coil. The housing 1 contains a conical core made of elastic antifriction material in the form of a package of pucks 9. The peripheral part of each washer is made of a crescent section, convexity facing the flange 4. When the tape 10 is moved by the drum, the crescent sections deform. washers 9, which fit into the surface of the bend of the tape with continuous self-tuning of the adjoining sections of the tape and core during operation. The stiffness of the elastic material of the washers 9 varies according to the height of the core. 1 hp f-ly, 2 ilo i (L

The invention relates to a technique for storing information, and m-ienHo, to cassettes for storing ring rolls using separate coils or cores,

The purpose of the invention is to increase the reliability and durability of the tape by reducing the value of the specific contact pressure in the zone of its exit from the coil.

Figure 1 shows the cassette, in plan view; figure 2 - section aa in figure 1.

The device comprises a housing 1 with a lid 2 and a conical core 3 accommodated therein with a flange 4s freely mounted on an axis 5 secured in the housing 1. In addition, the transport drum 6 and the guiding elements — roles 7 and lath 8 — are placed in the housing 1. Core 3 is made of an elastic antifriction material in the form of a packet of washers 9. The peripheral part of each of the washers 9 is made of a crescent section. The convexity of the cross section faces the flange 4,

The stiffness of the elastic material of each of the washers varies along the height of the core 3, the tape 10 is wound on the core 3 in the form of an endless roll, i.e. the ends of the tape 3 are connected in a ring.

The device works as follows.

The movement of the belt 10 is carried out by the drum 6. In this case, the belt is pulled out from the inner turn of the roll and wound onto the outer turn of the roll. Peeling of the tape 10 from the internal coil occurs with no

by which the force and pressure of the tape on the core 3, This causes deformation of the crescent-shaped peripheral sections of elastic washers 9, which fit into the bend surface of the tape 10 with continuous self-adjusting of the contacting sections of the tape and core during operation, resulting in a significantly increased area of contact of the tape and the core, and, consequently, the specific contact pressure in the zone of tape stretching decreases, which reduces frictional wear when the tape rolls off the core, ensuring high preservation of the surface of the rewindable tape.

Claims (2)

1. A cassette for an endless roll of tape, comprising a body with a pin and placed in it a tapered core with a flange, a transporting drum and guide elements, This is because, in order to increase the reliability and durability of the tape by reducing the specific contact pressure in the zone of its exit from the coil, the core is made of elastic antifriction material in the form of a package of washers, the peripheral part of each of which is crescent-shaped, the bulge of which facing the flange. 2. The cassette according to claim.), Differing from that, temd that the rigidity of the material TtWHoro of each of the washers varies along the height of the core.
