straight from the roll of film material, with a complete configuration that includes printing, heating, forming/ cutting, stacking and packing. To accompany the lids, Kiefel produced a range of
disposable cups on its Thermorunner KTR 6.1 Speed. Higher performance drive systems in this model help to increase production rates by to up to 45 cycles per minute.

range of materials, including PS, PP, PLA, PET and multilayer sheet. It is mainly intended for the produc- tion of tapered cups and tubs, but can easily thermo- form high-precision PP deep objects at high output. The forming area is 770 × 480mm, its cutting force is
57 tonnes. It can fit 51 cavities on a 70.6mm PP drinking cup, with an effective speed up to 57 strokes/min. The mould movement is driven through a torque
motor. All the other movements (index, cutting, stacking) are controlled through a set of servo motors driven by an axis control system and PLC. The machine is equipped with a quick mould changing system, fast air/water connections and a quick mould exit from the forming/cutting station (less than six hours for a complete mould change-over, from stop to restart).
European sales GN Thermoforming Equipment of Canada has already sold two units of its GN800 – a high-speed form/cut/stack thermoformer – to customers in Europe since K2016. The launch of the GN800 marks the company’s
entrance into the form/cut/stack market and expands its plug-assist machine offering. It was developed in partnership with Agripak of Italy, which manufactured and sold form/cut/stack thermoforming machines until 2003. “We saw the changes in the marketplace so wanted

to move swiftly to counter the competition,” said Jerome Romkey, business development manager at GN. “We used Agripak’s proven design, and combined it with GN’s own proven technologies.” The GN800 has a forming area of 800 x 570 mm (31.5 x 22.4in) and is capable of forming 150mm above and below the sheet line. The cutting force of the forming and cutting stations is 75 tonnes. The GN800 also has additional space between the forming and cutting stations, providing extra cooling time when running heavier gauge materials or PP. Kiefel showcased its Speedformer KMD

a greater forming area – increases the number of cavities. A newly developed pre-stretching plug is actuated by a powerful linear motor. Faster pre-stretch- ing has a positive effect on material distribution and processing speed.
Tilting platen WM Thermoforming Machines unveiled the Twist 700 – a new thermoforming machine with a tilting platen. It is designed to produce containers in PP, PP/EVOH and PET that require high quality standards and narrow dimensional tolerances. At the show, the company ran an In-Line extrusion and thermoforming plant to make PP cups. WM recently delivered its 110th In-Line plant system for extrusion and thermoforming – in Intec 900/3 – for the production of two-colour PP cups, to a customer in North America. It has also extended the In-Line range with the Intec FT 900/3, for co-extrusion of PP and PS. Amut Comi launched its new ACF series – including
the ACF 820, which combines the characteristics of the earlier V and F series to creating a model with a high level of standardisation, repeatability and durability, plus flexible production and increased high-speed perfor- mances. The range can handle different materials, and can produce many items including trays, lids, flowerpots and clamshells. ACF machines can also be integrated with a T-IML system (in-mould labelling for thermo- forming), in which a side-entry robot loads labels into the forming mould to decorate the articles. The use of steel rule cutting moulds makes this version more competitive than both existing T-IML systems – based on punch and die mould – and injection moulding.
