SPECIAL OPERATING INSTRUCTIONS FOR THE TWIN MACHINES
The Auto Wrap 1510/1514 can, as described earlier, also be supplied with a double set of wrapping
arms, film stretchers and cutters. This significantly increases the machine's capacity. This machine
is essentially the same as a standard machine, apart from a stronger davit and an extra valve block
for the wrapping arm motor which reverses the wrapping arm after the wrapping sequence is
completed.
It also has two cutters which are fitted on a hinged cutter beam on each side of the machine.
11.1
PREPARATION
Before the machine can be used, the wrapping arm must be "folded out" and the cutter beams
placed in their operating positions. See fig 2-8 and fig 11-1 for more detailed descriptions.
ADJUSTING THE CUTTER ARM.
The height of the cutters can be adjusted if, for example, the pinching arm does not hold the film
properly. Loosen the lock nuts and adjust the cutter arm to the required height. Tighten the lock nut
again. (See fig. 11-12.)
11.2
WRAPPING
Before the TWIN machines load up the bale, the wrapping arm must be positioned across the davit.
The wrapping arm is moved to the start position by pressing
"STOP" (9)
and holding it in. The
wrapping arm will now rotate at half speed, and when it reaches the correct position the button must
be released. Then fix both the film ends securely in the cutters. (See sections 6.4 and 6.5.)
When adjusting the overlap, (chapter 9.0), the roller speed is set to approx. 52-53% overlap between
the two prestretchers. This means that the rollers must rotate twice as fast as on a standard machine.
When the wrapping sequence is completed and the wrapping arm has stopped, the wrapping arm
will not be parallel with the bearer rollers. As soon as the cutters have closed, the wrapping arm will
automatically reverse back to the start position which is at right angles to the davit.
When the wrapping sequence is over the wrapping arm will be positioning a bit diagonal to the rollers.
When the bale is unloaded by pushing
ROLLERS OUT,
the wrapping arm will automatically return
to an 90° angle to the tower.
NB !
AUTO WRAP 1510 / 1514 TWIN is only constructed for use with 500 mm prestretchers. If there
are used 750 mm prestretchers, this is the user's responsibility, considering damages on the
machine and the wrapping- and feed-quality.
OBS! Before the machine is transported on public roads the wrapping arms and cutters must be
fixed in the transport-position.
