Based on extensive field research with actual users,
the Cousins Team has perfected a
new pre-stretch film carriage technology implementing
a pressure balanced nip roller
system to deliver pre-stretch results that are
far more precise to the pre-stretch ratio
than current industry standards.
Four precision bearing aluminum rollers pivot and
rotate around the pre-stretch rollers
on two axes of rotation. They lock into place through
counter-pressure applied from the
opposing roller (see Fig. 2). This increases film
to roller contact and significantly
improves traction. There are no springs that can
compress under load to create a gap
and allow film slippage.
Saves
money through improved performance, greater film to roller contact for
maximum film
yield.
Counter-pressure
maintains “nip roll” engagement throughout the wrapping
process. “No springs”.
Reduced
slippage means improved film clarity for scanning barcodes.
Can
be retrofitted to most competitive wrappers with a field retrofit kit.
Take advantage of the maximum pre-stretch capabilities
of today’s hi-tech films with the
patent-pending Super Rapid Thread Carriage. This
exciting new breakthrough in prestretch
technology dramatically improves pre-stretch carriage
performance.
Standard
safety-door style film carriages
are inherently inefficient as a result of
low film to roller contact. This results
in
film slippage. The higher the pre-stretch
ratio, the greater the slippage, the lower
the film yield and the higher the cost of
film used per load. Also resulting from
film slippage is poor film clarity, which
prevents bar code readers from reading
through the film.

Nip-rollers
#2 & #3 are
fitted on the film
carriage door. As the film carriage door
is closing there is contact and pressure
applied between nip-rollers # 2 & #3,
and the pre-stretch rollers.
This increasing pressure as the door
closes is in turn transferred to nip-rollers
#1 & #4, causing them to rotate in
against the back of the pre-stretch
rollers.
