Abstract

1341227 Moulded spools AGFA-GEVAERT AG 19 Jan 1971 [24 Jan 1970] 2582/71 Heading B8M An integrally-formed injection-moulded spool 1 is characterized in that the core is formed with a recess or recesses 3, 4, 5 parallel to the axis of the spool, opposite sides of the recess or recesses being formed by a rib or ribs 6, 7, 8 which extend from one side of the core to the other, and the ends of which form a supporting surface on each side of the core to which a label 9, 10 is secured. The recesses may all open on one side of the core, the ends of the recesses being closed by joining the ends of the ribs at the other side of the core, a continuous supporting surface thereby being formed. In an alternative embodiment, the recesses open alternately on opposite sides of the core. A central hole 2 is provided for the reception of a driving spindle. The spool is particularly suitable for magnetic tape or film.
