Shuster-Mettler Corp, USA, is a leading
manufacturer of tube, wire, and shaped
stock straighteners. The company has
developed a series of self-feeding and
high-speed straighteners used in the tubing
industry to straighten inline or from coils.
The Shuster models 2GRS, 3GRS, 4GRS,
and 5GRS gear driven tube and bar
straighteners do not rotate the material during
the straightening process. Instead they use 8
vertical rolls and 8 horizontal rolls to straighten
and feed the tubing. The 4-straightener
models cover thin wall tubing in OD sizes from
0.125" (3.2mm) to 3" (76mm).
The straighteners can be manufactured for
speed ranges to meet user requirements
up to a maximum production rate of 1,000ft/
min (300m per minute). Machines can also
be manufactured to user specified pass-line
height.
For continuous straightening, a single
motor and AC inverter drive is used on
all GRS machines. A servo drive is also
available on these machines for feeding
precise lengths into a press or other inline
equipment.
The company also manufactures a
complete line of non-powered 2 plane
roll type tube straighteners. Twenty-one
models are available covering thin wall
tubing sizes from 0.045" (1.1mm) to 1.875"
(47.7mm) OD.
