摘要:
A machine for folding and pressing the internal flaps of seams comprises a heated plate (1) in the body of which are formed separate chambers (6,7,8) respectively connected to a steam generator, a suction system and a cold air blower. These chambers communicate with a pressing surface of the plate itself through a series of holes. Facing the pressing surface of the plate (1) is a floating platen structure (2) having a corresponding series of holes (9) able to put into communication with the exterior two chambers (10, 11) in the facing floating platen structure, each chamber being separated into two parts by a partition (12) which divides it into two distinct portions.
摘要:
A sewing thread has at least on its outer surface at least one precursor of a product which confers to a stitched seam produced with such a thread an increased adherence to sewn materials. In addition, a sewing thread is disclosed in which the applied precursor changes into a product which is capable of increasing the outer diameter of the sewing thread, in particular in an aqueous environment. Finally, a process is disclosed for producing water-tight stitched seams. As indicated in the examples, the precursor is an expandable plastic or can contain inorganic expansion materials such as expanded pearlite, expanded mica or expanded graphite.
