Packautomatic optimizes rubber packing for LANXESS

LANXESS, a world-leading supplier of synthetic rubber contracted Packautomatic, from Ennepetal, Germany to develop and produce a packaging machine for its LANXESS Buna GmbH subsidiary in the Chemistry Park in Marl.

The plant was commissioned in early 2007.A conveyor system automatically feeds the rubber, which is compressed into a bale, from production to the packaging machine.
Prior to vulcanization, rubber is fluid and can change its volume if affected by temperature and pressure. So, first the individual bale is heat-sealed in foil. Next, they reach the so-called crate filler where each rubber bale is put into a cardboard frame. This prevents the rubber from flowing out, and provides for optimal pressure distribution.

A grip now takes the rubber bale and puts into it into a waiting packing case. To protect the commodity during transport, sturdy cardboard is inserted between each layer of rubber bales. Designed to work automatically right round the clock, Packautomatic's packaging machine is extremely flexible. It cannot only process different bale sizes but also different kinds of rubber. The advantages of the new machine are obvious:

Bale grouting under pressure has been optimized enabling the customer to process his rubber faster and more cost efficiently. Bales and the primary packing used to be in danger of damage from grips. The new grip is gentler.
Machine availability is higher, maintenance costs considerably lower.
Upshot: Pack faster, more securely and more flexibly.
