Abstract
Abstract A winding hub assembly for a record carrier in the form of a tape. One end of the tape can be inserted into and clamped in a circumferential recess in the winding hub with the aid of a clamping member, the hub having a further recess for a further clamping member adjacent to said first recess, the portion of the winding hub between the two recesses being elastically movable. The end of the record carrier is effectively clamped in position in the first recess through the action of the further clamping member in the further recess biasing the intervening hub portion.

Claim 1
Independent Claim
107 words
A winding hub assembly for a tape comprising a hub having a circumference, and first and second recesses having walls and terminating at said circumference, each recess having a restriction at the respective termination, said recesses defining a hub portion therebetween; said hub comprising means for allowing elastic deformation of said portion; a first clamping member arranged to be clamped in said first recess for clamping a tape between the first clamping member and walls of the first recess; and a second clamping member arranged to be clamped in said second recess so as to bias said portion toward said first recess, thereby clamping said first member.
