              Cestas de guía para film soplado


LS Series

· Traditional Systems with single IRIS. The mechanical system will vary in height according to number of levels.

· Interchangeable Guides. Guides are bolted on arms with 2 screws. The pitch is calculated to allow guides either with cylinders or segmented bushings.

· Precision on center fairly correct. Error from centerline varies from 0 to ± or in the range of IBC ultrasonic sensors installed on moving arms.

· The arm is done with a tubular support holding guides. The tube is not cold-bent but cut and welded to ensure a correct angle and precise vertical alignment of guiding arms.

· Guiding Levels. Multiple levels available, 2-3-4-5-6-7-8 according to customer requirements.

· The mechanics use a geometric pattern based on very common 8 shafts. The system does not have real advantages, only 4 IBC sensors have a better installation and can reach very small diameters.

· This construction does not leave empty corners. Bubble guiding with no noticeable vertical stripes.

Rettangolo arrotondato: LS / Regolazione Verticale cod. “RV”


This is the most efficient system for vertical positioning. Using heavy duty mechanical jacks 4 / 6 according to cage size. The lower part of the cage is “clean” free for placing any control for die activity. Transmission do not use chain but steel rods and universal joints. Cages shipped in sections take great advantage from this system.



For the LS sizes up to 3000 Layflat, we can offer also the more common cube structure.

Great care was applied on the design of parts eliminating completely the annoying wobbling as ¥ typical of this solution. The motor is placed in a protective position under the top frame. This way the top has no parts in the way.

Easy to install in the upper part gauge readers, break sensors etc.
