How
It Works...
The Quick Change Bar is machined specifically for the width and depth
of your slots. Strong springs, combined with "T"-shaped retaining
blocks, hold the bar and blade securely in the slot while cutting, yet
allow the bar to rock back easily for blade changes. Made from high-strength
steel, the bar is manufactured to tight tolerances for long life and reliable
operation. Setup time is reduced because there are no jacking screws to
adjust or shims to install. When height adjustment is necessary, the patented
central height adjustment feature provides precise control of the blade
height across the entire width of the bar. This is a valuable feature,
especially for difficult cutting jobs such as forms with microperforations.
Installing
the Tamarack Bar
Installation requires drilling and tapping two holes in the bottom on
the cylinder slot utilizing the jigs and drill guides provided in the
installation kit. Once this is accomplished the bar can be installed and
quickly secured.
Leveling
Adjustment
Most bars require
a series of "jack screws" be adjusted to level a blade, a tedious
and time consuming process.
The Tamarack QC Bar relies on a single point adjustment to accomplish
this. This is generally a one time adjustment which takes into account
any inconsistencies in the cylinder or bearing blocks.
- Assures parallel blade contact with the anvil to provide an even cut
all the way across the web.
- Because the interface between the bar and the adjusting slide is gently
curved end-to-end, shifting the slide off-center within the bar will
cause a very fine tilt for the perfect "kiss" cut.
- This adjustment "custom-fits" the bar to your slot. Once
set, it never needs further adjustment.
Central
Height Adjustment
- Precise control of the blade height provides a quick solution to common
job challenges such as perforating through thick stocks and microperfs.
- A series of ramps on the adjusting slides allow the bar to be raised
or lowered with the simple turn of a standard T-handle tool. This tool
engages in an internal rack and pinion system which moves the ramps
to raise or lower the blade, evenly across the entire width of the bar,
with micrometer-precision.
- This adjustment raises the entire bar, including a steel ledge which
supports the blade. When changing a blade, the operator simply places
the new blade on this ledge, maintaining the set blade height without
additional adjustment.
Changing
a Blade
The Tamarack Quick Change Bar is always ready to open using a simple,
T-handled tool. Rock the bar open, remove the old blade, and insert a
new one. Rock the bar closed, and the bar clamps the blade, ready to cut.
The blade change is completed in five seconds.
