B-Series

Blow-BLow Machines

WALTEC’s B-Series combines proven blow-blow technology with advanced servo-driven precision for efficient glass production.

Independently controlled drives for table and bottom rotation, bottom stroke and prepressing enable accurate, repeatable forming – including twisted optics and decorated glass bottoms. With 20 to 32 sections and speeds of up to 60 cycles per minute, the modular design supports reliable high-volume manufacturing and fast section changes. Combined with WALTEC’s ESERVO Stem Press, the B-Series offers flexible production solutions for high-quality tumblers and stemware.

Engineered for process stability, easy maintenance and long-term performance – Made in Germany.

Feeder

Always the perfect gob – 
flexible press operations

WALTEC’s ESERVO feeder system supports single, double and triple gob production through independently operated feeding mechanisms on a single feeder head. Depending on the production mode, the individual feeders are automatically activated or parked, ensuring maximum flexibility and precise process control.

ESERVO Components

Improved sustainability – 
significant energy savings

Modernize existing glass production with WALTEC’s ESERVO retrofit solutions. Replacing conventional hydraulic and pneumatic systems with precisely controlled servo technology reduces energy and compressed-air consumption while improving process accuracy, repeatability and production efficiency.

B-Series – Production Lines

The Blow-Blow process

Linear feeder, servo-driven shear (parallel or angular) and gob chute are manufactured with the well-known WALTEC technology. The sturdy and precise running main drive of the machine allows the feeding of the working table with perfectly synchronized motion. The gearless, direct-driven transfer arm follows the rotation of the working table without any mechanical support.

Prepressing is realized by a servo rack and pinion. Independent servo drives for working-table and bottom rotation and a servo drive for the bottom stroke allow easy adjustment of twisted optics and decorated bottom designs. This enables excellent repeatability and a stable process for start-up, job change and production.

Available Options

Servo bottom rotation
Servo bottom stroke 450 mm
3-part working tables
Electrical mould heating
Burner tracking system
Rotating unloader
and much more!

For your process-optimized production: Future-proof technology

Central lubrication as well as oil circulating lubrication for gears and bearings are WALTEC standard. They guarantee longest production cycles without any maintenance. Due to the modular design the section change can be performed within the shortest possible time. In line with the control systems for our blow-blow lines, we have minimized the electrical components on top of the machine. A slip ring transfers the power. For the highest reliability, the control signals are transferred via the slip ring.

With the blow-blow machine, WALTEC has developed and built a user-optimized machine, according to the requirements of the glass manufacturers. In combination with the WALTEC stem press, a state-of-the-art production line for manufacturing the highest-quality tumblers and stemware is available.
