摘要

Apparatus for cutting and guiding the marginal or lead-in strip formed in a paper web and used in connection with a lead-in operation thereof includes first and second guide plates extending at an angle relative to each other and with which are associated nozzle tubes in which nozzle apertures or the like are formed for directing air jets parallel to the first and second guide plates. The first guide plate is oriented so as to correspond to the direction in which the end of the paper web is to be conducted onwardly after severance of at least the forward portion of the lead-in strip. The second guide plate is oriented in a direction which corresponds to that in which the marginal or lead-strip is conducted into a pulper or the like. Air jets are directed from the nozzle apertures over the respective guide plates so that the latter act as guiding and air transport surfaces so that the marginal lead-in strip is pulled in different directions in the area of the guide plates until it is severed. The new end of the web or marginal lead-in strip is conducted onward under the guidance of the first guide plate. A guide plate element is preferably provided forming a continuation of the first guide plate in order to guide the new end of the web or marginal strip onwards to subsequent guiding apparatus.
