Abstract:
1. An expanded metal machine, comprising: a) a stationary knife and an adjustable knife which is adjustable in a vertical direction and a transverse direction, the adjustable knife including a cutting edge with spaced-apart cutting projections in the transverse direction, the transverse direction extending transversely to the vertical direction, and the vertical direction and the transverse direction determining a plane; b) a transport device for transporting a flat material in a direction of transport between the knives; c) a cam configured for performing a periodic vertical motion; d) a transverse adjustment device configured for adjusting the transverse motion of the adjustable knife in the transverse direction and in a manner synchronized with a traveling motion; and e) an eccentric drive being provided for the cam, thereby guiding the cam in a circulatory motion which runs in the plane determined by the vertical direction and the transverse direction.
