Problems solved by technology

This takes a lot of time and also requires performing a lot of action positions around angle adjustments
It is also not possible to ensure that all adjusted angles are also in harmony with each other
Inconsistencies in the angular position of the side guides can lead to increased folding waste during the flattening of the blown film

Embodiment Construction

[0032] all three attached Figures 1 to 3 Shows the different adjustment modes of the individual lever moving parts 30 and thus the correspondingly different adjustment angles α k 、α e 、α a Design way. Referring also to the three figures, for example, the diameters of the individual blown films 100 also differ from one another. The diameter of the blown film 100 is adjusted or the required adjustment angle α k 、α e 、α a In particular, there is a correlation between the blown film being specified by the discharge diameter (not shown) of the film blowing head 300 .

[0033] combine figure 1 Further briefly explain the working principle of the present invention. In this embodiment, the blown film 100 is produced by a film blowing head 300 not shown. Blown films generally have a circular cross-section. The blown film moves along the conveying direction F towards the pulling roller arrangement 200 . The traction roller arrangement 200 has at least two traction rollers, w...

Abstract

The invention relates to a guiding device (10) for guiding a blown film (100) between a film blowing die (300) and a take-off roller device (200). The guiding device (10) comprises at least two lateral guides (20) located opposite one another for laterally guiding the blown film (100), wherein at least one lateral guide (20) is provided with a first guide segment (22a) and a second guide segment (22b), which are connected to one another in an articulated manner. At least one lever kinematics (30) is provided, which is in drive connection with a drive device (50), and which is interconnected with the two guide segments (22a, 22b), such that when the drive device (50) is actuated by way of the lever kinematics (30), the angles of attack ([alpha]a, [alpha]e) of the two guide segments (22a, 22b) to the conveyance direction (F) of the blown film (100) can be varied.

Description

technical field [0001] The invention relates to a guide device for guiding a blown film between a film blowing head and a pulling roller arrangement and to a method for adjusting the adjustment angle of the guide part of the guide device which is guided on the opposite side. Background technique [0002] Guides for guiding blown films are known in principle. It is described, for example, in WO 2009 / 000510 A2 and WO 2009 / 000511 A2. In principle, this is a blown film production device. Often a film blowing head which produces the film tube is used for this purpose. The film tube should then be clamped flat by laying the two opposite sides of the blown film on top of each other. In the pulling roll arrangement, the cross section starting from the roughly circular shape of the film blowing head becomes a clamped flattened cross section, viewed in cross section. Guiding means have been used in known manufacturing installations of such blown films. They have, for example, cli...
