Horizontal stretch wrapping machine Python 1000 – 3200

rotary ringfully-automaticfor long products

Our Python is designed for horizontal stretching of products. At the same time a film carriage with a film roll is mounted on a rotary ring. The rotary ring is driven by a frequency-controlled motor, which enables any speed of the rotary ring and therefore an adjustable film overlap at a fixed conveying speed. After the last wrapping has been completed, the wrapping is thermally cutted and clamped for the start of the next wrapping cycle. - Massive machine frame - machined running surfaces for higher rotation speed - sequential ring bearing for diameters up to 3 200 mm Film carriage The film carriage is mounted on the rotary ring and is equipped with a mechanical pre-stretching system. Ring drive The power transmission from the geared brake motor to the rotary ring is effected by means of flat belts, whereby the longitudinal elongation of the flat belt during accleration and deceleration of the raceway is compensated by a pneumatic tensioning unit. Rotary Ring The rotary ring is a steel ring which is machined onto concentricity and balancing and is supported via polyurethane coated rollers. The number of the rollers depends on diameter and speed. Film clamping device The film is held in two clamping arms. After a pre-set number of wrappings on the display, the clamping arm opens and the film gets released. Due to the forward wrapping, the beginning gets already wrapped. During the last wrapping, the clamping arm gets also wrapped and the film clamped. The film is thermally cut and the end gets rubbed on the package. After separation, the package runs out of the wrapping machine.
