Leverkusen 10-fü-ki Spool take-up mandrel for F reels

The innovation relates to a bobbin take-up mandrel for fumspulen.

For certain reasons it may be necessary to rewind a film from one reel to another. This can be done in a known manner by a rewinding device which is arranged, for example, directly on a motion picture projector.

However, such rewinding devices are expensive and expensive. For this reason, the amateur in particular tries to rewind with makeshift means. With these forms however, rewinding is difficult and time consuming.

The task of the innovation is therefore to create a simple and cheap option for rewinding.

According to the innovation, this object is achieved in that a bobbin receiving mandrel which is known in its design is provided with an adhesive surface at at least one axial end. With this measure, the bobbin receiving mandrel on a smooth, adhesive surface, for example on a table or on a device cap Motion picture projector. Another such Spool take-up mandrel is attached at a corresponding distance from the first bobbin take-up mandrel. On the a spool take-up mandrel can then hold a full spool of film be attached, while the empty film spool is attached to the other spool mandrel, on which the film is to be rewound. Complex rewinding devices are therefore no longer necessary. The makeshift means with which the amateur has made it up to now are no longer applicable extremely cheap to manufacture spool mandrels, for example with motion picture projectors or with the film reels can be supplied.

In a first embodiment of the innovation, the adhesive surface is formed by a suction cup. In a second embodiment of the innovation, the adhesive surface is formed by an adhesive film. Both possible solutions are beneficial depending on their purpose.

In a particularly advantageous further development of the new article, the bobbin receiving mandrel has a bore. into which a crank bolt can be inserted. Diener crank bolt is also provided with an adhesive surface at one axial end. Spool take-up dome and crank pin can be delivered together. The crank bolt supplied is placed on the film reel to be driven during rewinding so that it rushes. ■ »Handle for driving can form.

Further advantages and details of the new t * ....? & Im the following explained in more detail with reference to a drawing. Show it:

Fig. 1 is a section through a first embodiment of a Spulenauf sewing mandrels according to the innovation, wherein on the spool take-up mandrel a film spool is attached,

Fig. 2 shows a second embodiment of a Bobbin mandrel according to the innovation,

Fig. 3 shows the appropriate arrangement of two spool mandrels according to the innovation for rewinding a film.

According to FIGS. 1 and 2, there is a bobbin receiving dome as a whole

denoted by 1. Vie from Fig. 1 shows the

la bobbin receiving dome 1 has an axial bore into which a

Crank pin 2 is inserted. On the mandrel 1 is

a film reel marked 8 is attached. The reel mandrel 1 itself can be shaped to accommodate either a normal 8 film reel or a Super 8 film reel. Both the reel mandrel 1 and the crank bolt 2 have adhesive surfaces, formed by adhesive films J and 4, & uf. As can be seen from Fig. 2, the adhesive surfaces S and 6 for the bobbin receiving mandrel 1 and crank pin 2 are formed by suction cups.

As can be seen from FIG. 3, two coil mounting domes 1 and 1 * are fastened at an appropriate distance from one another on a flat surface, for example a table or a housing part of a motion picture projector. Film reels 7 and 8 are placed on reel mandrels 1 and I ¹ , for example the full film reel on reel mandrel 1 and the empty film reel onto which the film on film reel 8 is to be wound on reel mandrel 1 '. A crank pin 2 is attached to the empty film reel 7 on the flange above it. This serves as a handle for driving the empty reel 7 in the direction of the arrow 9. The crank bolt 2 associated with the reel mounting mandrel 1 can be used to axially secure one of the two film reels. 7 or 8 can be attached to the spool mandrel 1 or 1 * that carries them.
