Linear feeder, servo driven shear (linear or angle) and gob delivery system 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 a perfect 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 servo drive for the bottom stroke permit easily adjustable twisted optics and decorated bottom designs. Hereby, we achieve the best repeatability and a stable process for start-up, job change and production.
Central lubrication as well as oil circulating lubrication for gears and bearings are WALTEC standard. They guarantee longest production cycles without any maintenance.
With the blow-blow machine, WALTEC has developed and built an user-optimized machine, according to the requirements of the glass manufacturers. In combination with the WALTEC stem press, a production line of the latest state of the art for manufacturing highest quality tumblers and stem ware is available
