An improved rotary cutter for a web material is proposed. It has a pair of rolls adapted to rotate synchronously in opposite directions and an axially elongated knife secured to each roll to extend axially. A plurality of rolling bodies are arranged around each roll to bear the shock upon cutting. Different means for preventing the knives from hitting the rolling bodies are proposed. This arrangem...

A method is indicated for length measurement on precision winding appliances, which is based on a measurement of the bobbin diameter and on determining the rotational speeds of the bobbin. The variable bobbin width and the variable pitch angle of the thread helix during the winding operation can be taken into account or a correction by the introduction of variously designed correcting cycles can b...
