US Patent:

52956350, Mar 22, 1994

Filed:

Aug 28, 1992

Appl. No.:

7/936476

Inventors:

John J. Niedospial - Princeton Junction NJ
Russell J. Butler - Dansville NY
Christopher P. McCormick - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B65H 7528

US Classification:

242 74

Abstract:

A spool to film attachment comprises a filmstrip having an engagement hole formed in a rear end of the filmstrip proximate a rearmost film edge and a spool having an engagement projection adapted to be received in the film hole. The projection has a pointed side oriented to face the rearmost film edge from within the film hole, when the projection is received in the film hole, to be able to tear at a predetermined point through a relatively narrow section of the filmstrip between the film hole and the rearmost film edge in response to pulling the rear end of the filmstrip away from the projection.

Abstract:

A film cassette comprises a cassette shell, a spool core supported inside the cassette shell for rotation in an unwinding direction to advance a filmstrip coiled about the spool core out of the cassette shell and in a winding direction to draw the filmstrip into the cassette shell, at least one flange coaxially coupled with the spool core to prevent the filmstrip from uncoiling about the spool core and to permit the flange and the spool core to be rotated relative to each other in the unwinding and winding directions, and cooperating means located on the spool core and the flange for fixing the flange and the spool core to each other to make the flange rotate with the spool core in the unwinding direction but releasing the flange to permit it and the spool core to be rotated relative to each other in the winding direction. According to the invention, stop means are connected to the cassette shell, and the flange has engageable means for being engaged by the stop means when the flange is rotated with the spool core in the winding direction to prevent the flange from further rotating in that direction, whereby the flange will impose a frictional drag on the filmstrip as the filmstrip is wound onto the spool core to cause the filmstrip to be wound tightly to the spool core.
