nylon tube converting line

Working with leading manufacturers in the truck and commercial vehicle sector, Metzner
have developed automatic converting lines to process truck brake pipes which
provide enormous benefits to the users.
The tubes, with diameters of between 4mm and 16mm, are drawn by the Metzner machine from a
coil, cut to exactly the right length and printed to the customer’s specification (ink jet or laser printing,
thermal transfer printing or with adhesive labels) and then stacked, bundled or wound. At the
end of a material roll, the machine gives an optical signal and a message on the display. The operator
can then load another material roll to continue the automatic production without interruption.
Depending on the number of pipes per vehicle, a Metzner converting line of this type produces
brake pipes for 50 to 100 vehicles per shift and the machinery is fully integrated into the customer’s
computer-aided manufacturing system. The data sets for the production are transferred from a
central computer to the converting line, which then sends back the necessary status information.

Weight saving for energy conservation is one of the main themes in vehicle design. Metzner
is playing its part in this by the development and supply of converting machinery for
pre-preg material used in the manufacture of vehicle components.
The machines designed by Metzner first monitor the quality of the pre-preg material at a speed of
1 metre/second using a camera system. Defective material is cut out and separated. The defect-free
material is cut into the required lengths and arranged according to pre-set plans in numerous layers
and in different positions. Certain vehicle components also require cut-outs and shaping of the pre-preg
materials and subsequently the exact positioning of the cut relative to a material feature.
The machine then performs further quality control functions with automatic documentation and backtraceability.
