Printing automation for bottle
caps
Principally designed to print directly onto
PP & PE caps and closures,
the TAMPOflex "BIG WHEEL”system satisfies
the need for high speed,
low cost production of such items.
The rotary print heads feature an environmentally
friendly closed inkwell system, together with easily
accessible cliché drum and roller pad designed for ease
of service and maintenance.
Intended to be integrated into fully automated
production lines, the dual stream machine takes
a continuous feed from product orientation equipment
via two lanes to the periphery of the rotary carrier
where it is loaded and retained on
a precision tooling system.
Print heads transfer images from the clichés drum
via a rotary pad at a tangent to the product surface.
Exact synchronization in perfect registration is
ensured by direct drive of the print heads from
a master gear wheel driving all the
moving components.
The synchronized print heads have individual
fine adjustment, controlled to produce continuous
and repeatable accuracy of print transfer.
Take off mechanisms are arranged
to release and remove the printed items,
re-orientate and advance to down stream
drying and packaging stations.
Owing to the precision which is required
of this system, cliché drums are etched
using an especially accurate process
of film handling utilizing optical positioning to
guarantee absolute accuracy of registration.
