Abstract
This invention relates to A press felt for a paper making machine comprising a batt layer portion adapted to be positioned on a paper making machine juxtaposed the path of a paper web and a base weave portion designed to receive water from the paper sheet and to carry the batt layer, and means for jointing first and second ends of the felt to form a continuous belt, wherein the felt is provided at a first end portion with a flap in which the batt layer of the felt is configured to form a flap and at a second end portion, is configured to cooperate with said flap end portion characterized in that at least one of said end portions is coated with a hot melt adhesive whereby on the bringing of the first and second end portions into juxtaposition, the application of heat and pressure to bond said ends permits the formation of a seam in which the flap element overlays the remainder of the join in the felt.
