650 PLS – Cam lock differential shaft

Description

The cam lock differential shaft is composed by a series of self-expanding rings able to wrap independently several reels with different width, maintaining the same settled tension during the wrapping.
The self-expanding rings assembled on the chromium plated and grinded shell body will block the rigid cardboard core by expanding shortly on the rotating direction. A pneumatic rotary joint secured at the shaft end is adjusting the air pressure injected into the differential shaft. The air pressure range is from 0 to 6 Bar connected to the external reel diameter and to the settled tension. The differential ledges under the rings can be manufactured in different type of material according to the client’s need, therefore are interchangeable. The force of friction produced between the differential ledges and the self-expanding rings generates a perfect and independent reels rewinding. To get the best rewinding on reels you must assure that the differential shaft speed will be higher than the machine speed. The rewound reels can be easily re-moved by a small rotation on rewinding opposite direction.
