It features unique technical solutions which include the film reel holder shaft
positioned on the side of the machine body instead of the traditional rear position; the
introduction of the self-centring film tracking unit positioned on the top of the frame that
guides the film towards the forming tube and the drastic reduction in the number of idle film
rollers that transfer less inertial energy to the film allowing for greater acceleration.
The operating principle: from continuous to intermittent motion.
The operating principle of the machine is based on a motor driven reel-holder shaft that
rotates constantly and the film pulling and sealing unit that moves intermittently. An
electronic compensating dancing roller transforms the constant movement of the film
arriving from the reel shaft into an alternating movement towards the sealing units. Thanks
to this principle, the use of the mechanical reel brake is not required anymore and the
overall machine dynamics is very smooth thanks to the film stretch management that can
be programmed by the software. The first 6 film idle rollers rotate constantly and only 2
rollers move intermittently. As a direct consequence, the inertial energy is not transferred
to the film and it is possible to increase the acceleration of the film and / or the sealing
time, which greatly benefits productivity and the aesthetics of the pack.
Productivity:
The R700 machine guarantees exceptional performance. The reduced number of rollers,
the unique operating principle, the simple and effective mechanics of film pulling and
sealing, together with powerful software, allows the R700 to run at a mechanical speed of
up to 150 cycles per minute.
