Calender for treating web-like materials with adjustable rollers
The patent US12031272B2 describes a calender designed for the treatment of web-like materials, featuring a fixed structure that supports two heated rollers. These rollers are arranged to form a nip through which the web-like materials can pass. Each roller is equipped with a right and left pin, each pin having two bearings spaced apart. The calender includes two lower and two upper levers that can move to contact the bearings, applying forces in different directions. Each lever is connected to an actuator that allows for rotation around a horizontal axis, enabling the levers to switch between an engagement position, where they interact with the bearings, and a release position, which facilitates the removal of the rollers from the calender.
Additionally, the calender incorporates various features for enhanced functionality. Each lever has a concave part for better interaction with the bearings, and the structure includes side walls that support the levers. The actuators controlling the levers and other components are managed by a programmable unit, allowing for automated operation. The rollers are designed with internal ducts for heating fluid circulation, and valves controlled by actuators manage the flow of this fluid. Furthermore, the rollers can be moved using external mechanical means, such as a bridge crane, while maintaining specific temperature ranges. The design also includes thermally insulating chambers and air circulation systems to optimize heating efficiency. Overall, the calender's innovative design aims to improve the treatment process of web-like materials through precise control and automation.
