Calenders shall be equipped with an emergency stop device. Emergency stop devices shall comply with the requirements of 5.7 of EN 1034-1:2000 and EN 418:1992 and shall act on all hazardous movements of the machine. This includes the movement of electric, hydraulic and pneumatic drives of calender rolls, unwinding, winding, threading, sheet feed devices and lifting platforms.
Actuators for emergency stopping are also required in areas that need to be accessed for cleaning. As a deviation from 5.7 of EN 1034-1:2000, in cases where it is not practicable to complete the whole stop procedure with a closed roll nip, it is permitted to open the nip even before standstill is attained if the safety devices are designed so that they prevent the drawing-in hazard with the nip both closed and open. Additional requirements for emergency stop devices of lifting platforms are contained in 5.20.1.
5.3.2
Calenders shall be provided with braking devices which operate on actuation of the emergency stop device. This requirement can be fulfilled, for example, by mechanical brakes or electric regenerative brakes. Braking devices shall operate in such a way that the stopping time of the machine does not exceed the shortest possible start-up time following emergency stopping. 5.3.3
The control system of emergency stop devices shall comply with at least category 3 of
EN 954-1.1996.
The emergency stop device shall be effective according to stop category 1 from 4.1.5 of
EN 418:1992. SIST EN 1034-6:2006
EN 1034-6:2005 (E) 13 5.3.4
The control system of electric brakes shall comply with at least category 2 of EN 954-1:1996. Any fault in the brake control system shall lead to emergency stopping according to category 0 from 5.1.4 of
EN 418:1992. 5.3.5
The emergency stop control system of on-line calenders shall be integrated into the emergency stop control system of the paper/smoothing machine in such a way that the emergency stop devices of the other machine units also act on the calender and the calender emergency stop devices also act on the other machine units
It shall be ensured that all the safety-related parts of the linked emergency stop control system correspond to category 3 according to EN 954-1:1996.
5.3.6
The use and checking procedures of emergency stop devices shall be described in the instruction handbook. 5.4 Web threading and sheet feeding 5.4.1
For threading the paper web on off-line calenders with high roll stacks, for example super calenders, lifting platforms are required which satisfy the requirements of 5.19 to 5.21. 5.4.2
On-line calenders shall be provided with a threading device, for example, a rope threading device. 5.4.3
Sheet calenders require devices for feeding the paper sheets. 5.4.4
Safe working practices for threading the paper web and joining the web ends shall be described in the instruction handbook. 5.4.5 The wrapping points of the threading device according to 5.4.2 and the device according to 5.4.3 shall be safeguarded in accordance with 5.4.2 of EN 1034-1:2000. 5.5 Workplaces, access stairs, catwalks, passageways
