Embodiment Construction

[0040] figure 1 A packaging machine 1 according to the invention is shown having a deep drawing station (forming station) 2 , a filling station 7 and a sealing station 15 . The lower sheet web 8 , here the plastic sheet web 8 , is withdrawn from the backup rollers 52 and transported along the packaging machine according to the invention from right to left in a timed manner. At one clock, the lower sheet web 8 continues to be transported for a format length. For this purpose, the packaging machine has two transport devices (not shown), in this case two endless chains each, which are arranged to the right and to the left of the lower sheet web 8 . Not only at the start and end of the packaging machine, respectively, at least one gear wheel is provided for each chain, around which the corresponding 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 shafts. Each tran...

Abstract

The invention relates to a packaging machine (1) which unwinds a lower film web (8) from a backup roller (52) and transports it intermittently or continuously along The packaging cavities (6) are formed into the lower sheet web (8) and these packaging recesses are then filled with packages (16), wherein the upper film web (14) is subsequently sealed at the sealing station (15) is sealed to the lower film web (8), wherein the upper film web (14) is unrolled from the backup roller (22). Downstream of this backup roller there is arranged a floating roller (20) with at least one, preferably two rollers (23.1, 23.2), which are arranged on a linkage (23.4), which ( 23.4) Rotation driven by the rotary drive about the axis of rotation (23.3) and thereby store a length of film web (8, 14) and / or generate the desired stresses in the film web (8, 14).

Description

technical field [0001] The invention relates to a packaging machine with floating rollers, sheet brakes, gluing stations and / or sheet rollers. Background technique [0002] Such packaging machines are known from the prior art. In the case of said packaging machine, the lower sheet web is unrolled by backup rollers and is preferably transported intermittently along the packaging machine. In the forming station, packaging cavities are first formed into the lower web, which are then filled with packaging, in particular food. Next, in the sealing station, the packaging cavity is closed with the upper sheet sealed onto the lower sheet. The sheet web is likewise unrolled here by the backup rollers. In this case, floating rollers are arranged between the backup roller and the sealing station, said floating rollers having to be adapted to the forward pull of the lower web as it advances. For this purpose, in the past it was necessary to separately provide the floating roller ele...
