Abstract

The invention relates to double trimming shears having a stationary bottom knife and a driven top knife which can be raised and lowered, wherein the top knife is arranged on a top knife carriage (12) guided by means of a carriage guide (10), wherein a first eccentric shaft (14) and a second eccentric shaft (16) on the carriage guide (10) is provided in order to guide the carriage guide (10) if an inclined position of the top knife carriage is to be prevented. This is achieved in that the first eccentric shaft (14) and the second eccentric shaft (16) are interconnected via a synchronization means (18).
