Abstract

304,738. I. G. Farbenindustrie Akt.- Ges. Jan. 25, 1928, [Convention date]. Roll spools.-The film is attached to the spool by making cuts in the film of such shape that, when the end of the film is curved, tongues are formed at the cuts which can engage automatically in corresponding slots in the core of the spool or a neighbouring part. The cuts 2 may be arcuate as shown in Fig. 1; and the end of the film may be curved. to cause the tongues 3 to protrude, by inserting it, for example, between the spool core and a curved blade spring which is fixed thereto and has a corresponding slot for engaging one of the tongues 3.
