      Reliable unscrewing of caps

      Decapper for removing screw caps

      With its variety of set-up options, the Rotomat perfectly complements the modular concept of a returnables line. Its flexible design makes it possible to match the decapper to the available space and the operating conditions in the respective bottling lines.

      Method of Operation

      The decapping head consists of three grippers, each with two contact points to the cap. As a result, the cap is gripped at a total of six points and then unscrewed. The use of a tracing pin with a damping device enables removal of even slanted, loose or overtightly screwed-on caps whilst protecting the threads. 

      The decapping head is equipped with a mechanism which compensates tolerances of bottle and cap heights. Rllers ensure low-noise and wear-resistant closing and opening.

      Bottles that enter the machine without a cap are detected by the tracing pin. In these cases, the grippers remain open. This prevents unnecessary damage to the neck finish.

      Benefits to you

      Reliable operation

      The Rotomat safely unscrews caps of up to 50 millimetres and is not impeded by wet container surfaces. It even removes caps that are positioned at a slant or screwed on too tightly without damaging the thread. If a cap is missing, the decapping head remains open, thus preventing damage.

      Easy handling

      Conversions can be easily performed thanks to the automatic height adjustment of the decapper's top part. Thanks to low-wear decapping heads, the system is also easy to maintain and service.

      High level of hygiene

      The design of the machine follows the requirements of hygiene -especially through the consistent reduction of surfaces and clear separation of the drive unit and the decapping area by means of a table top.
