Technowrapp specialises in the design and production of automatic stretch wrap film pallet wrappers and pallet movement systems. The company has made a name for itself on the international scene by developing an innovative and creative solution, the Runner Arm. This is exclusively equipped with Bonfiglioli motors.

Through its close collaboration with Bonfiglioli, Technowrapp has created Runner Arm, a perfect combination of high performance and simplicity of operation and maintenance. Bonfiglioli´s comprehensive and reliable motor solutions have ensured that Technowrapp is the trusted partner of leading firms in the packaging and logistics sectors.

Technowrapp constantly faces new technological challenges to supply the market with cutting edge solutions such as the Runner Arm in order to improve quality, performance, and production. With 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. Thanks to two specific patents that make it possible to speed up the wrapping process, Runner Arm can achieve the unrivalled result of wrapping 136 pallets an hour with 10 turns per pallet, stabilising a pallet with just 76 grams of 15 micron stretch wrap film. These two patents have produced the fastest arm pallet wrapper in the world.

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. Runner Arm has revolutionised pallet wrapping and can satisfy customer demands more completely that ever before.

Bonfiglioli contributed to the success of Runner Arm through its extensive product portfolio. Technowrapp used 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 0,75 kW. In addition, the tensioning and plier carriage are equipped with W63 and BN_FD motors, with motor powers of 0,55 kW for the tensioning carriage and 0,37 kW for the plier carriage. The tensioning carriage also utilises a W86/BE motor with a motor power of 1,1 kW. The arm rotation uses Bonfiglioli´s W110/BN_FD motor series with 4 kW of motor while the presser uses a W63 BN_FD motor with 0,55 kW of motor power. Lastly, the linear roller uses the C22 BE series with 0,75 kW of power.

These motor solutions have helped Runner Arm achieve outstanding speeds while maintaining low structural stress. In addition to providing cutting-edge motors, Bonfiglioli is a unique supplier that provides outstanding development, maintenance and spare parts management.
