An attachment for sewing machines for folding and pressing seam plies for sleeves, trousers and the like having a pair of endless belts or tapes between which the cloth being sewn is carried. After the seam has been sewn, the cloth is carried forwardly into the path of a V-shaped seam opening member which causes the seam plies to be separated, be positioned at right angle to the cloth and lie on either side of the seam in a common plane. Upon being carried further forwardly, the seam plies engages a seam folding member which guides and folds over the seam plies from their right angle position to a flattened position against the cloth whereby the seam plies lie in substantially the same plane as the two layers of cloth after which the heated rollers and a hot air blower presses the four layers of cloth in superimposed contact relation. A floating bow-like member positioned between the endless tapes supports the two layers of cloth as the seam is folded and permits the sewing of a seam to be sewn along both edges of a trouser leg portion.
