ABSTRACT:
A device for longitudinal cutting of a thermo-softening material into strips, such as strips of a separating material for battery electrodes comprising a roll holder, two pulling rollers having their rotation drive installed parallel and near to said roll holder, and said rollers moving the band in the course of cutting and delivering the cut strips onto the receiving shafts of a wind-up mechanism. A common shaft parallel to the pulling rollers is located under a cutting mechanism and carries electric cutters secured on arms; the hubs of said arms are fastened with the aid of intermediate sleeves on said common shaft. Both the hub and the intermediate sleeve are provided with segment teeth which interact with each other during the turning of the common shaft thereby lifting automatically the electric cutters.
