Device for applying a dandes * consisting of two layers of different compositions

The fire relates to a device for applying a tape consisting of two layers of different composition, whether one layer of the tape consists of heat-sensitive adhesive laterally and the other layer at the same temperature , at. the first layer becomes adhesive, remains heat-stable, without a tear; ^he frame with pivotably mounted on it for a pressure roller, a freely rotating element heatable roller with a peripheral surface guiding the tape and an or several guide rollers arranged on the flag, one of which, for guiding the strip tangent to the circumference of the roller, has an axis parallel to the axis of the roller.

Ribbons or strips of various kinds are in large size for reinforcing or closing containers, especially those made of cardboard or VJellpappe, in which

(. \ as /ar.G for: closing the striking cap d.ient, used. Such ', "? Bunders have an adhesive strip on one side, and a tight bond with the surface of the container . to ermügli chen recently, s ^have: ch in particular tapes rv'.t a thermoplastic adhesive layer proven for their rnbriin ^ un · the previous heating the adhesive layer ξγΓorderli cn.

For the one- or two-sided lamination of a Flächennato rial devices of the type mentioned have become known which have at least one pressure roller pivotably arranged over an arm and have at least one insertable roller, on the surface of which the tape is guided and the thermoplastic adhesive layer is heated will. A well-known device; of this type (DT-Gbn 1 857 77o) represents a uniform frame through which the surface material to be concealed runs through. Such a device is Γϊτ the application of an adhesive tape to an object or a surface is not suitable because the device r.'t de: r. Adhesive tape must be handled independently of the object to be glued. Send out. 5 ^Ί 'ηά in this known Voi "r' chtun £ the pressure roller or pressure rollers and Kei: roller or heated rollers so arranged and constructed that not iirjner ^e; ne gle 'chmässi ^ e and stress-free Erv / ärmung the adhesive Mater i all and maintenance of the warming up to the Knd back η;

The underlying task of the fire is a simple one also movable and guidable with respect to the material to be glued To create a device in which the band to be applied

only gradually heated up, so as not to be sudden To expose temperature fluctuations and thus tension.

To solve this problem, it is proposed in a device of the type mentioned that the heating roller as Pressure roller is arranged acting on the pivotable arm and that the guide roller leading the belt tangentially to the circumference of the heating roller at such a distance and such a distance Position to the heating roller and the axis of the arm is arranged that that to the heating roller and, with the heat-resistant layer facing this, around this band led during its Urnlauf with the largest part of the circle circumference of the Heating roller, preferably with about 3/4 of the circumference, in

^: Contact remains.

^! The main features of the innovation are

thus to see in

a) that the heating roller itself is arranged on the freely swinging arm and at the same time the function of the pressure

^ Role fulfilled and for the application of the tape

b) represent. the tape on a longer circumferential surface around the Heizroll * is performed, so that a uniform and Distortion-free heating is enabled.

The device is particularly simple in that the heating film is also a pressure roller. The pressure is by the weight of the heating roller itself or by others

suitable means, such as counterweights, compression springs or the like. Generated. The even heating is possible through reached far around the tape around the heating roller. It has been recognized that with the simultaneous training When using the heating roller as a pressure roller, particular attention must be paid to the fact that in the contact point of the tape on the material, which lies on the circumference of the heating roller itself, a complete and even, not too sudden heating of the tape material must have taken place.

A structural design of the invention is characterized in the dependent claim. An embodiment of the invention is described in more detail with reference to the drawing. Show it:

1 shows a side view of a tape application device according to the invention and

FIG. 2 is an end view, partly in section, of the device of FIG. 1.

The device shown in Fig. 1 and 2 consists of a support frame, designated 14, for adjustable displacement is mounted on a horizontal guide rail 16 with the aid of a guide 15. As shown, the setting can take place by a rack 17 on the rail 16 via a gear 18 engaging in this, which on a Shaft 19 is attached, which is stored in the guide 15 and operated by handwheel 2ο.

A plate 21 connected to the guide 15 is pivotable at 22 an arn 23 attached, at the free end part of the macaw 23 an axis 24 is attached, on which a free-running ileizrolle 25 is stored. The heating roller 25 has a smooth one Circumferential surface 28 in any suitable way heated v; can be grounded. As shown, the heating means exist from an electrical IJ. "derstandskorper 27, which is in a housed on the peripheral VJ to extension adjacent chamber 28 is. Electricity for the heating means is supplied via cable 3o and a connecting terminal 31 which connects a pair of thirsts 3 2 in Has contact with a pair of contact rings 3 3 on the roller wheel hub. Contact parts (not shown) connect the ping rings with the resistance body 27.

The heating roller 25 is only mounted on its circumference so that it rests on a plate 35 made of cardboard, corrugated cardboard or the like, which are intended to serve as a container wall. Slide mat. 35 lies on a suitable surface 3G. The plate 35 may be in the arrow direction along the surface 36 to a geeigente • ■ • 'are moved else, v / odurch simultaneously ^d: e Heizrclle is rotated 25th Conversely, of course, the device could be moved relative to the plate 35 or another object to be glued. The pressure exerted by the control roller 25 on the plate 35 can be regulated with the aid of an adjustable counterweight 37 which is seated on a rod 3C attached to the arm 23.

A band Io is inserted into the device as; da.s tape with a larger part of the circumferential surface 25 of the roller 25 comes into contact. As shown, \; 'ra the 3And over free-running guide rollers 39 and 4o, which on straps 41 \ ma 42 on the frame 14 is attached are supplied, which is initially upwardly passes over the roller 25, and then further
