Abstract
An apparatus transfers a lead strip of a paper web, in particular the beginning of a still wet lead strip or tail, from a press roll of a paper-making machine to a following section of that machine. An air jet device peels off the beginning of the tail from the press roll and transfers it across a paper roll to an infeed area of a felt which guides the web into the following section. On an infeed area of the felt, an air cushion is created by an air table having a plurality of tiny holes delivering air from a low pressure plenum to the air cushion.
