VBW 600/ 800/ 1200

VBW 600 / 800 / 1200

The right solution for any material: with Dietze+Schell systems and plants

The strap winder family is used for winding straps in parallel directly from the extruder. These machines come with one or two winding mandrels. Versions with two bobbin mandrels permit particularly fast manual bobbin swap.

Networking of individual machines joins the winding positions together into production lines. The compact design permits use even in confined spaces.

The machines were designed for continuous operation. They wind 4 to 32 mm wide PP or PET straps based on specific winding programmes. Dietze+Schell customises them based on specific customer specifications.

Basic equipment

Central operating terminal with visualised programme guidance. The current production data of the individual winding positions or a summary of the entire line can be displayed here. This is also used to enter the winding parameters and to create and distribute winding programmes to keep equipment times short.
Dancer control for controlling of a constant strap tension and winding speed
Precise, electronically controlled 2 or 3 point laying with minimal strap bend of the straps
Pneumatic lamellar spreading mandrels for fast bobbin changes

Options

Second bobbin mandrel for fast bobbin change in a matter of seconds
Laying stroke up to 300 mm
Bobbin build-up between flanges
Smoothly variable slip feeder for tension-free pre-supply of the strap
Strap storage to supplement the production line
