August 21, 2015 – Technowrapp, a firm specializing in the design and production of automatic stretch wrap film pallet wrappers and pallet movement systems, developed Runner Arm, that can wrap 136 pallets/hour with 10 turns per pallet, stabilising a pallet with just 76 grams of stretch wrap film.

The Runner Arm is exclusively equipped with Bonfiglioli motors. In the Runner Arm automatic rotary arm pallet wrapper, Technowrapp engineers have succeeded in combining the high performance of a ring wrapper with the simplicity of operation and maintenance typical of an arm type wrapper. The rotary arm with centripetal contrast ring contains and guides the arm as it moves and makes it possible to reach a speed of rotation of 45 revolutions per minute, combining this with low structural stress. The cutting and welding pliers operate on the moving load, contributing to the increase in speed and efficiency of the work cycle. The result achieved is the wrapping of 136 pallets per hour.

Technowrapp utilized Bonfiglioli´s C, W, and BE/BN motor series for the pallet and vertical carriage movement as well as the ring rotation and the servo-assisted tensioning systems. The various Bonfiglioli motors were used for the tensioning, feeder, and plier carriages as well as for the presser and linear roller, The carriage system is equipped with Bonfiglioli´s W63 and BN_FD Motors with a motor power of ,75Kw. In addition, the tensioning and plier carriage are also equipped with W63 and BN_FD Motors, with motor powers of ,55 Kw for the tensioning carriage and ,37kw for the plier carriage; the tensioning carriage also utilizes a W86/BE motor with a motor power of 1.1Kw. The arm rotation uses Bonfiglioli´s W110/BN_FD motor series with 4Kw of motor while the presser uses a W63 BN_FD motor with ,55Kw of motor power. Lastly, the linear roller uses the C22 BE series with ,75 Kw of power. These various motor solutions have aided Runner Arm achieve outstanding speeds while maintaining low structural stress.
