Lloyd Instruments TG5093 Peel Fixture
for Heat Sealed Plastic Film Covers on Food Containers
This fixture consists of a small upper spring loaded wedge grip to clamp
the film container cover, and a horizontal sliding bed fitted with a
"dish holder".
A mains operated vacuum pump with associated piping
and vacuum control valve is used to apply vacuum to the "dish holder" to
retain the food container securely in position during the test. The
wedge grip is fitted to the supplied threaded adapter and connected to
the upper anchor pin on the loadcell.
The sliding bed fixture is connected to the lower
anchor pin. Once the pump is switched on, the food container sample may
be positioned in the holder and the vacuum control valve adjusted so
that there is sufficient force to restrain the dish when the plastic
cover is peeled off. The sliding bed is positioned so that the loose
part of the cover is located below the upper wedge grip. By lowering the
moving crosshead, so that the wedge grip is just together to open the
jaws, allowing the edge of the cover to be positioned into the jaws. The
levers may then be released and the test carried out.
