Embodiment Construction

[0022] The drawing shows a device which is used for sealing a molded film 1 with a filled basin 2 with a covering film 3, wherein not only the forming film 1 but also the covering film 3 is not shown in the drawing Provided on the supply roll and guided if necessary by means of guide rolls between a heatable sealing roll 8 and a feed roll 5 . The feed roller 5 is drivable by means of a roller drive 4 and has recesses 6 for forming the pockets 2 of the film 1 on its peripheral surface. as specifically from figure 2 As can be seen in 3 and 3, a pressure chamber 15, which in the exemplary embodiment shown is several, is provided in the feed roller 5. The pressure chamber 15 is connected via a pressure medium line 16 to a pressure medium source 17 . The feed roller 5 consists of a material with a small modulus of elasticity (E-modulus), which is significantly smaller than, for example, the E- modulus. Plastics and among them especially polytetrafluoroethylene (PTFE) can be us...

Abstract

The invention relates to a device for sealing a molded film (1) with a preferably filled basin (2) with a covering film (3), having a Feed roller (5) with recess (6) for pot (2) and a sealing roller (8) running above it, between which the forming film (1) and cover film can be guided (3), a pressure chamber (15) is set in the feed roller (5), which is connected to a pressure medium source (17) through a pressure medium conduit (16), so that the change of the circumference of the feed roller (5) Accurate correlation of the positions of the pelvis (2) and the recess (6) is achieved.

Description

technical field [0001] The invention relates to a device for sealing a formed film with a preferably filled pot with a cover film, which has a feed roller that can be driven by means of a roller drive and has recesses for the pot on its peripheral surface and a sealing roll running thereon, between which the forming film and cover film can be guided. Background technique [0002] The difficulty when sealing the formed film is to precisely adjust the position of the cavities formed in the feed roller relative to the pots in the formed film, so that during the operation of such a device it may happen that the pots are not positioned exactly In the pocket and thus the basin suffers damage at the edge of the pocket. In order to avoid such damage to the formed film it is known in DE 10 2004 010 202 B3 to arrange the feed roller as a two-part construction with an indexing arranged parallel to the axis of rotation of the feed roller, wherein the feed roller consists of two compone...
