Embodiment Construction

[0040] figure 1 A packaging machine 1 according to the invention is shown having a thermoforming station 2 , a filling station 7 and a sealing station 15 . The lower web 8 of sheet material, in this case a web of plastic sheet material 8 , is withdrawn from the supply reel 52 and transported in a cyclic manner along the packaging machine according to the invention from right to left. On the course of a cycle, the lower web of sheet material 8 is transported forward by the length of a plate. For this purpose, the packaging machine has two transport means (not shown), in this case two endless chains, which are arranged to the right and to the left of the lower sheet material web 8 . At the start and end of the packaging machine, each chain is provided in each case with at least one gear around which the respective chain is deflected. At least one of these gears is driven. The gears in the entry area and / or in the exit area can preferably be connected to each other by rigid s...

Abstract

The present invention relates to a packaging machine (1), which unrolls a lower film web (8) from a supply roller (52) and transports it intermittently or continuously along the packaging machine and thereby forms packaging recesses (6) in the lower film web (8) in a forming station (2), after which the packaging recesses are filled with a product (16) to be packaged, wherein an upper film web (14) is subsequently sealed onto the lower film web (8) in a sealing station (15), wherein the upper film web (14) is unrolled from a supply roller (22). Provided downstream of the supply roller is a dancer (20), which has at least one, preferably two rollers (23.1, 23.2), which are provided on a linkage (23.4), which, driven by a rotary drive, rotates about an axis of rotation (23.3) and thereby stores a certain length of film web (8, 14) and / or produces a certain tension in the film web (8, 14).

Description

technical field [0001] The invention relates to a packaging machine with floating rollers, a sheet material brake, a bonding station and / or a roll of sheet material. Background technique [0002] Such packaging machines are known from the prior art. In the case of said packaging machine, the lower web of sheet material is unrolled from a supply roll and transported along the packaging machine, preferably intermittently. In the forming station, in the first case, a packaging cavity is formed in the lower web of sheet material, which is then filled with a product, in particular a food product. Thereafter, in a sealing station, the packaging cavity is closed by the upper sheet material being sealed onto the lower sheet material. The sheet material web is likewise unrolled from a supply roll here. A floating roller is provided between the supply roll and the sealing station and must be adapted to the forward pulling performed by the lower web of sheet material during the adva...
