Bandimex Air Tool

The BANDIMEX air tool is an air controlled, automatic tensioning tool for applying BANDIMEX performed clamps.
Operated by pedal – both hands are free to manipulate the object to be clamped.
An ideal, proven tool to clamp hose, cables and ropes of various constructions with outer diameters of 10 to 200 mm.
Each clamp is pulled down with exactly the same preset pressure in seconds.

BANDIMEX performed clamps come in 21 diameters and combinations of 5 band width, a total of 38 various clamps are available. If this is not enough on request we can also manufacture additional combinations of diameters and widths.

Installation of air tool

Screw down base plate to the work bench in such a manner that the tensioning head has sufficient distance to the edge of the bench to allow easy and unobstructed mounting of clamps on all sizes hose.
The air inlet is a ⅜“ male thread with a mounted nipple suitable for quick connect coupling ID 7,2 mm. Pressure setting at the incorporated service unit should not be less than 87 psi (6 bar), and not more than 116 psi (8 bar), it is set at 102 psi (7 bar), when tool leaves factory.
Fill vessel of oiler (service unit) with special oil for service units (e.g. Festo OFSW-32), adjust set screw of oiler to obtain minimum oil mist in air stream. Keep insides of aluminium guide rails well greased with Molykote or other high grade grease. Check the two cutter blade screws for tightness once in a while.
The footpedal may be screwed to the floor.

Adjusting functions

On the tables and pressure gauges settings are shown in ‚bar‘ and ‚psi‘. For exact adjusting ‚psi‘-settings should be employed.

1. Pull Pressure

Step on pedal – piston is pulling in (keep the pedal down!) – turn knob and set pressure reading on the gauge to the pressure required according to band width of clamp (refer to schedule) - loosen counter nut on top of knob before turning, and fasten again after setting

2. Pull Speed

Loosen counter nut
Slower: Turn screw to the right
Attention: Don’t turn the screw past stop
Faster: Turn screw to the left
Press down pedal repeatedly while adjusting until requested speed is obtained.

3. Timer

This unit regulates the period of time between beginning of cycle (pressure build-up), and release of the pressure, and rules the time used for applying a clamp. When the clamp is pulled down and piston stops at the set reading, the pressure should remain for 1 or 2 seconds to allow the clamp to settle.
Less time: Turn the knob to the right
More time: Turn the knob to the left
Max. time delay: 10 seconds
The timer is set at approx. 2 seconds by manufacturer. (Depends on length of pull down of clamp tail.)

4. Hold Pressure

In order to keep the clamp from losing tension during the cut-off operation, and to guarantee a secure locking of the buckle, a certain amount of pressure must be maintained in the cylinder. This pressure varies according to width of band and the nature (composition) of the hose (refer to schedule), and is set in the same manner as described under 1., but after the timer has released the pull pressure.

For type 316 steel (CrNiMo) use 10% less, for Hi-C steel 30% less pull pressure.
The above values for pull and hold pressure are approximate.
They may vary according to the types of hose and couplings applied.

Operating Instruction

1. Push tailed end of preformed clamp into tensioning head.
2. Step on pedal (keep depressed until clamp has been cut-off)
3.   3. After timer has released pull-up pressure (this moment will be marked when the air will deflate from the tool with a hiss) and the value for the hold pressure will be shown on the pressure gauge on right side of panel, roll up hose together with clamp. After roll-up, the cutter hook will engage on top edge of buckle.
4. Pull forward cutter lever – cut off clamp.
5. Release pedal – piston returns – remove band tail.

KEEP PEDAL DEPRESSED UNTIL CLAMP HAS BEEN CUT OFF!
