Leather bandage
The leather bandage or friction bandage is an endless tire made of upright leather strips that are connected by rivets .
The bandages are used for all screw presses ( friction screw presses ). There are cylindrical or conical bandages, depending on the type of press. It rests on the face of the flywheel (which sits on the spindle ) and rubs against one of the two drive disks.
For them, the tough, elastic and yet stable chrome leather with a special tanning process with an extraordinarily high natural coefficient of friction is used. This special chrome buffalo leather does not smear and always guarantees reliable friction . The consistently tight riveting of 30 mm increases the stability of the bandage. The riveting is not done in the middle of the strips, but close to the inner edge, so that there is more "meat" in front of the rivets and the usable strength of the bandage is greater. The bandages are manufactured without a connection point, they consist of one piece, so to speak.
