Welex: 1 ton/hour V-Pet System

Friday, August 17th, 2001

Welex, USA, will exhibit the newest member of their World Standard family of complete hopper-to-winder sheet extrusion systems at K 2001 in Dusseldorf.
The line will feature the new 130 mm 30D Mark III vented extruder to run via the Welex V-PET system, which significantly minimizes the need for predrying PET. Stated line capacity running APET sheet for packaging is 1100 kg/hr.This size was developed specifically to satisfy the rapidly rising demand for lines to produce one ton per hour of quality thermoforming sheet. The same line can also run HIPS at similar capacity, or PP at somewhat lower capacity — without any changes whatsoever.

B A Thorne: Coilers for varying lengths

Tuesday, August 14th, 2001

Extruders producing odd lengths of profiles or hose in coils now have a UK source of coiling equipment. Generally coiling is done manually or on a simple coiler built in-house. Uponor Group company Unicor Extrusionstechnik builds a range of coilers for this type of work, and these are now available in the UK through B A Thorne (Machinery).

The basic machines are turntable coilers from 80 to 120 cm diameter with cutting, changeover and tension-free coiling from outside to inside or vice versa. Multi-layering is possible together with interleaving of virtually any material. The process is controlled by a dancer arm which feeds a signal to a Siemens PLC. More complex equipment is available with multiple stations, automatic changeover, banding, foil wrapping, boxing and other options.

Its vacuum contact roller ensures optimum film transport and enables winding with a minimum of web tension. For the first time Kiefel now is able to cover the full spectrum of winding technology - from simple surface winders to high end winders.

Merlin Process Equipment: Mixer can discharge partial batches

Thursday, August 9th, 2001

The latest HM Series Horizontal Mixer from Merlin Process Equipment Co.,USA, (formerly Henschel Mixers America), has a significant new feature: It can now discharge partial batches, where previously the mixer discharged its entire contents at once. The HM mixer now has a specially adapted discharge valve, that can open and close again after discharging part of a batch. This allows the mixer to fill several gaylords from one batch, for example. The mixer retains its hydraulic clamshell lid, cross-flow mixing action and optional high-speed choppers. It can also be jacketed for either heating or cooling.
