Abstract: A description is given of a process for forming a film pack, in which an article to be packed is wrapped in a single web of packing film (1) by the said article being pressed against the web of plastic film (1) drawn off a supply roller, so that the said film forms a pocket and, behind the article, comes together again and forms a stem part, which is clamped together. After this, the - two-ply - stem part of the film is welded at a point next to the clamped position on the side away from the article to be packed, creating a heat weld (e) along a transverse line and the weld is severed transversely. As a result, the article thus packed is detached, while the continuous form of the drawn-off film web is maintained, that is to say the weld half not remaining on the packed article is attached to a short length of scrap film web on the one hand and to the part of the film web coming from the supply roller on the other hand and joins these parts of the film web to each other. After that, after detaching the packed article from the remaining film, the film portion with the heat weld is pulled away as scrap film (4) and the next article is pressed against and into the film following behind, this weld in the film web already having been drawn off to such an extent that it is no longer on the pack of this next article.

Title: Method and device for the relative assignment of sample quantity supplier and sample vessel
IPC: B01L3/00
Filed: 1989-02-13
Abstract: The invention relates to a method for the relative assignment of sample quantity supplier and sample vessel and a device for carrying it out. By means of a method of this type, using coded sample vessels in a fixed arrangement in a detection magazine, a relative assignment is ensured between sample quantity supplier and sample vessel, without detection of the position of the sample vessel in the detection magazine being necessary. According to the method, this is achieved, inter alia, by moving coded sample vessels without alignment in an arbitrary fixed arrangement into, preferably, a standardised detection magazine, at a first location, and reading at a second location the coding of a sample vessel in an arbitrary position, transferring the sample from a specific sample quantity supplier into the identified sample vessel and assigning the coding of the filled sample vessel to the identification of the specific sample quantity supplier. For carrying out the method, a device is provided in which, inter alia, the tripods (7a) are tilted transversely to the row of sample vessels, so that, seen in the longitudinal direction of the sample vessel, an axial offset (H) of the sample vessels is produced between similarly-positioned sample vessels (1a, 1b; 1b, 1c) of adjacent tripods, in the region of which offset a reading device (5) is driven, unhampered by the sample vessel of the adjacent tripod (Fig. 5). <IMAGE>
