1 set |
CROSS-CUTTING UNIT |
|
for cutting the fabric to the preset length and consisting of: |
|
intermittent traction system with servomotor |
|
print mark reading device for printed tubular fabric |
|
pneumatically operated knife including brake valves in the end positions |
|

INTERMITTENT FEED SECTION WITH MAGNETIC TRANSPORT |
|
is the zone where the fabric length is cut. Consequently, the fabric is constantly decelerated and accelerated. The variations in speed are compensated by the compensator. The intermittent feed section consists of: |
|
intermittent magnetic transport unit |
|
Servo-drive with self-referencing function, thus ensuring a precise sack transfer |
|
manually adjustable (depending on the sack dimension) bottom opening station |
|
transfer station to the continuous transport section |
|
|
1 set |
CONTINUOUS FEED SECTION |
|
is the zone where the sack is transported at a constant speed by magnetic transport to the different folding devices and welding stations. The continuous feed section consists of: |
|
bottom closing by means of adjusting spindles |
|
belt system for the transport of the sacks via an acceleration belt from the main machine to the stacking unit |
|
|

VALVE UNIT |
|
The valve patch, which has been cut from flat fabric, is applied onto the sack and welded by means of hot air. The valve unit consists of: |
|
unwinding station with band brake, monitoring system for fabric end and automatic control for guiding the fabric length |
|
pneumatic expansion chuck
|
|
traction unit with separate servo-drive for the infinitely variable adjustment of the patch length |
|
cutting unit for the valve patches |
|
hot air welding device |
|
|

BOTTOM PATCH DEVICES |
|
The bottom patches, which have been cut from flat fabric, are applied onto the closed sack bottoms and welded by means of hot air. The bottom patch devices consist of: |
|
unwinding station with band brake, monitoring system for fabric end and automatic control for guiding the fabric length |
|
pneumatic expansion chuck |
|
traction unit with separate servo-drive for the infinitely variable adjustment of the patch length during the operation |
|
print mark reading device for printed bottom patches |
|
cutting unit for the bottom patches, adjustment of the knifes. |
|
hot air welding device |
|

|
position-controlled servomotors with transport system without pins |
|
Duplex chain drive |
|
control elements |
|
drive connections to the other drive units by means of a software coupling |
|
|
1 set |
ELECTRICAL INSTALLATION |
|
central power distribution for drive, heating and control systems |
|
control cabinet, completely installed and checked when connected to the line |
|
optimized energy distribution and protection of the line components |
|
modular machine structure for add-on and retrofit purposes |
|
highly advanced safety and monitoring equipment with checking system |
|
separate bus system for the drive system and the control level, including a clearly structured diagnosis system and an integrated software temperature control |
|
control cabinet cooling by circulating air, for unlimited ambient temperatures |
|
