Thread pressing machine. Patented in the German Empire on September 17, 1920.

There are machines' known in which threads with several on a turntable

in addition to a device for applying o. The like. Arranged thread insertion heads that

a sealing compound in the liquid state one after the other with a rolling device and

on a can lid a device for «inem combustion head cooperate, and with

Is arranged rolling on the edge of the lid. those liftable in the thread insertion heads

In contrast, the invention relates to cover plates are arranged, on a pressing machine for sealing The invention consists in that the in

the vertically displaceable thread insertion head arranged cover plate vertically is resilient, liftable and rotatable, so that this plate for the purpose of rolling is lifted, but for the purpose of pressing the sealing thread back into the thread insertion head raised for this purpose.

The invention is shown in the drawing in an old guide form serving as an example.

Fig. Ι shows in a schematic way the overall arrangement of the new machine, while Figs. 2 and 3 show details on an enlarged scale in section. According to Fig. 1 , two thread insertion heads b are arranged on a turntable a, one of which is located below a burner head c , while above the second head b a rolling head d cooperating with a laterally movable roller ^{d 1} is arranged, which is arranged in any and known manner, e.g. B. by means of a pulley e, can be set in rotation. So that the attachment plate used to hold the lid / when rolling on the lid edge forms a rotatable abutment for the rolling head, while in the insertion head b when the rubber thread is pressed onto the lid edge it can move back into the thread insertion head b in a known manner, each thread insertion head b is for example like this formed, as can be seen from Figs. Thereafter, the cover plate / * is provided with a pin h , which is rotatably mounted inside the thread insertion head b and a sleeve b ¹ on a track plate b ^2. With the sleeve ^l b h b is the pin by an engaging into a pin Xut Ii ^{1 s} connectedness, to which prevents only a displacement of these parts> against each other. At the lower end, the sleeve b ^{1 has} a recess b * . L ^T m this sleeve b ¹ is a further sleeve 0 disordered on which the insertion head b is supported

If the edge of the cover is to be rolled on, the cover plate / is lifted by the plunger i as shown in Fig. 2, with the insertion head b being taken along as these parts are connected to one another by a screw. During the movement of the table α , the recess /) ^{4 of} the sleeve b ^{1 is} pushed into the claw-like end of the plunger i , which can be raised and lowered by a cam disk I by means of a spring j and a sleeve k. This allows one of the covers.

load-bearing lid attachment plate f firmly, however, as a result of the activated spring / resiliently pressed against the rolling head d , so that the crimping roller d ¹ that is brought up rolls onto the edge of the lid. The outer edge of the thread insertion head b is expediently cut out so that the flanging roller can be brought close to the cover plate /.

After rolling, a sealing thread is immediately pressed onto the cover. For this purpose, the insertion head b moved forward with the turntable α is lifted with respect to the combustion head c by a plunger m (Fig. 3) also controlled by a lifting disk with the intermediary of the sleeve 0 . The lid attachment plate f , which is resiliently supported in the insertion head b , is taken along, but can then move downwards when the lid hits the combustion head c , since a recess η is provided in the interior of the plunger m for this purpose.

Claims (3)

Patent Claims: i. Thread pressing machine with several thread insertion heads arranged on a turntable or the like, which cooperate in succession with a rolling device and a combustion head, characterized in that the cover plate (/) arranged in the vertically displaceable thread insertion head (b) is mounted vertically resilient, liftable and rotatable, so that this plate (/) is lifted for the purpose of rolling, but for the purpose of pressing the sealing thread back into the thread insertion head (b) raised for this purpose. 2. thread pressing machine according to claim r, characterized in that the cover attachment plate (f) is rotatably mounted in a hollow shaft (0) of the thread insertion head (, b) which is vertically displaceable with this and for itself also vertically displaceable sleeve (for ¹ ), and the Displacement of the sleeve (Z? ¹ ) for rolling on the cover, which of the hollow shaft (o) is used for pressing the sealing thread. 3. thread pressing machine according to claim i, characterized in that the effective when pressing the sealing thread, only the insertion head (b) lifting plunger (■; ») at the upper end has a recess («) into which the bearing sleeve (b ¹ ) of the Can top plate (/ ') can enter. 1 sheet of drawings.
