Abstract
A press felt for use in a paper, cardboard or tissue machine, with an open, load-carrying base structure which, viewed in longitudinal direction of the press felt, includes seam loops on one end, as well as seam loops at the other end, whereby the seam loops on the one end and the ones on the other end can be brought together for the purpose of producing the endless press felt and can be intermeshed with each other, so that a pass through opening is created through which a pintle can be guided, and comprising a machine side fibrous nonwoven structure which is located on the base structure and which provides the machine side of the press felt and which, viewed in longitudinal direction of the press felt, has one end section and one other end section, whereby when viewed in longitudinal direction of the press felt, the seam loops respectively extend at least partially over the end sections of the machine side fibrous nonwoven structure. In at least one end section of the machine side fibrous nonwoven structure an elastomeric polymer material is provided which is formed from a polymer or pre-polymer which was added in liquid form into the press felt and subsequently solidified or cured and which extends in the at least one end section from the machine side fibrous nonwoven structure into the base structure.
