Definitions

• the invention relates to a hand-held device for transferring a film from a carrier film to a substrate with a housing, in which a supply spool and renewed winding spool for the carrier film are accommodated in each case on a pivot pin mounted rotatably in the housing, wherein we ⁇ At least one spool is assigned a backstop, the two pivot pins are coupled to one another via a toothing with a slip clutch that is effective in the " direction of rotation " and the carrier film that can be unwound from the supply spool is pressed through a protruding from the housing Carrier film with its film side on the substrate provided application element and from this back into the housing on the take-up reel.
• a supply reel and a take-up reel are arranged side by side in one plane, a carrier film coated with an adhesive being wound on one side of the supply reel.
• the take-up reel which is comparable to a tape cassette empty reel, is intended for receiving the used carrier film.
• Both spools are arranged in an openable housing, which makes it possible to replace the supply spool and remove the take-up spool.
• An outstanding application element is arranged on the outside of the housing, and the coated carrier film is guided over the edge thereof facing the substrate. This application element is placed on the substrate to which the adhesive is to be applied.
• the adhesive film is separated from the carrier film, which at the same time is rewound without adhesive from the winding roll.
• a device is only functional if the carrier tape is sufficiently tensioned at all times.
• the supply reel and the take-up reel are connected to one another via a drive connection which has a slip clutch.
• the drive connection is designed in such a way that, as with a tape recorder, the take-up reel tries to rotate so quickly that it not only picks up the carrier tape drawn off the supply reel, but also keeps it taut.
• Such a device is known for example from DE-OS 36 38 722.
• the drive connection is designed as a toothing, the two rollers being seated on pivot pins mounted in the housing.
• the gear of the pivot pin for the take-up spool is smaller than the gear of the pivot pin for the supply spool, so that the take-up spool inevitably rotates faster and thus tensions the carrier tape.
• the gear for the take-up spool is made in one piece with the corresponding rotary pin
• the rotary pin for the supply roll and the corresponding gear are designed as individual parts which are connected to one another via an elaborate slip clutch.
• the slip clutch consists of resilient pawls, which are fastened to the drive gear, and a supply spool receiving mandrel with an internally designed splined hub, into which the pawls engage.
• the drive connection with a slip clutch is therefore relatively complicated and in particular of a multi-part construction, which makes the manufacture complex and thus cost-intensive, which is a decisive disadvantage for such a mass article.
• the object of the invention is to improve such a hand-held device to the effect 'that the An ⁇ number of components is reduced and the production can be fanned ippo ⁇ .
• the hand-held device according to the invention only has a pivot pin with integrated teeth for the supply spool or the take-up spool and does not require any additional elements for the slip clutch.
• the teeth of the pivot pin for the supply spool are designed with lamellar tooth necks in the area between the ring gear and the tooth flanks, and that the teeth of both pivot pins are in the plane of the tooth flanks are beveled perpendicular to these, such that the teeth of the pivot pin for the supply reel can be slid over the teeth of the pivot pin for the take-up reel at a speed difference.
• the slip clutch does not consist of a separate element, but is directly part of the toothing.
• the sloping teeth of the supply reel which are resilient due to the lamellar design of their tooth necks, can slide over the correspondingly beveled teeth of the pivot pin for the take-up reel.
• the response of the slip clutch can be controlled via the spring properties of the teeth of the pivot pin for the supply spool.
• the spring properties are due to the design of the lamella shaped tooth necks can be influenced, depending on the requirements, the length and thickness of the tooth necks and their lamella shape can be varied.
• the invention further provides that the backstop is assigned to the toothing of the pivot pin for the supply spool, the backstop being particularly advantageously designed as a correspondingly beveled housing element in the area below the beveled teeth, such that the teeth of the pivot pin can only be slid in the direction of rotation over the housing element.
• the backstop is assigned to the toothing of the pivot pin for the supply spool, the backstop being particularly advantageously designed as a correspondingly beveled housing element in the area below the beveled teeth, such that the teeth of the pivot pin can only be slid in the direction of rotation over the housing element.

• Fig. 4 shows a section according to arrow IV in Fig. 2 and
• a hand-held device for transferring a film from a carrier tape 1 to a substrate 2 which is only indicated, has a housing which is formed by two housing halves, a lower housing half 3a and an upper housing half 3b.
• the two housing halves 3a and 3b can be plugged together by means of pins 4 in the housing half 3b and corresponding pin receptacles 5 of the housing half 3a to form a common housing.
• Zv / ei bearing journals 6, 7 for pivot pins 8, 9 are formed in the lower housing half 3a.
• an annular support 10 is additionally formed in the foot region of the bearing journal 6.
• the housing also has an outstanding application element 11 for the carrier tape 1, which is formed by triangularly tapering guide strips 12a or 12b in both housing halves and an application roller 13.
• This application roller 13 is rotatably supported in a pin which is formed from a pin 14 of the housing half 3b and a sleeve 15 of the housing half 3a, with this pin when the housing halves are joined together arises.
• grip surfaces 16a, 16b are formed on the outer surfaces in both housing halves.
• the housing half 3b in the area facing the bearing journal 6 has an elongated opening 17 through which one can look into the interior of the housing.
• the pivot pins 8, 9 are formed in one piece with a toothing 18 or 19, wherein teeth 20 of the toothing 18 are larger than teeth 21 of the toothing 19.
• a disk-shaped plate 22 is formed on the foot of the pivot pin 9 below the toothing 19.
• the pivot pins 8, 9 can be placed on the bearing journals 6, 7 accordingly and, after the housing halves 3a, 3b have been joined together, are rotatably mounted in engagement with one another without axial play, wherein corresponding bearing devices can also be formed in the housing half 3b are not shown.
• a supply spool 23 carrying the carrier tape 1 and a winding spool 24 winding the carrier tape 1 after the adhesive has been applied to the substrate 2 can be plugged onto the pivot pin 8, the spools being connected in a rotationally fixed manner to the pivot pins, which is not shown in the drawing.
