6 The HAVER ROTO- 3 PACKER series RL desig- nates a rotating valve-type bag filling machine (with 3, 4, 6, 8, 10 or 12 spouts) 2 according to the air type filling system. The area of application includes pow- der type, fine or coarse 1 grain, flow resitant prod- ucts or mixtures with fine and coarse components, granulates, crystals or goods of similar particles.
The average operational 11 output using paper and 12 plastic bags with interior valves is between 900 bags/hr. with 3 filling spouts, and 4000 bags/hr. 5 with 12 filling spouts. By combining the ROTO- PACKER with the HAVER RADIMAT automatic bag applicators (bundle or reel system), fully automatic operation is possible. 6

13 HAVER ROTO-PACKER details
HAVER filling shutoff valves – as slide gate valve or pinch valve are always functional and reliable over the long term.
Advantages:
• high weight accuracy by exact material flow dosing • 3-position cylinder for full and fine flow • manual or motorized adjustment of fine flow opening • extremely low product adhesion • optimum interaction between weighing parts and stationary parts • air tight closing of Slide gate valve Pinch valve filling channel • tried and proven system, even under extreme conditions
Among other aspects, the spillage rejecting flap offers a big improvement in bag cleanliness. During discharge, the rejecting flap prevents the bag from becoming contaminated with product that could drip out of the filling tube. Activation of the rubber flap occurs pneumatical- ly.

17 RADIMAT automatic bag applicator for valve type bags
As an automated system for the ROTO-PACKER, the HAVER RADIMAT valve type bag applicator represents a significant potential for plant ratio- nalization:
General advantages:
• modular design • standardized for a wide range of bag types • automatic adjustment for varying bag sizes • self adjustment with respect to the ROTO- PACKER rotary speed
Minimized machine down times are the direct result of the RADIMAT’s use of a tried and proven, low maintenance, drive system.
Other decisive factors HAVER RADIMAT bundle system with respect to produc- tivity include the SPS controlled processes and a bag feeding reliability that doesn’t adversely affect the subsequent filling system.
This allows the use of large diameter filling tubes for achieving:
• high filling speeds • excellent weight accuracies • exceptional bag cleanliness
The work operations and functional steps together with a HAVER ROTO- PACKER allow filling rates of more than 4000 bags/hr.

21 HAVER reject screens for foreign bodies and packing plant design
NIAGARA reject screening machines for removing foreign bodies To assure trouble free operation of packing plants that use impeller filling systems, it is rec- ommendable to remove foreign bodies that may be present in the product.
The closed NIAGARA reject screening machine was specially developed by HAVER for this purpose.
For light operation, the free-swinging system is suitable.
For heavy duty, high pro- ductivity operation, the NIAGARA screening machine with the eccen- tric drive shaft system is HAVER screens for foreign bodies in closed version (assembled) the best choice.
