FIELD: manufacture of web for papermaking machine.
SUBSTANCE: method involves providing spiral winding of band-shaped woven web, said web having first and second lateral sides, along which first and second edges are respectively extending, each of said edges comprising at least one longitudinal thread interwoven with transverse threads. First and second gaps are arranged adjacent to first and second edges inward thereof, wherein said gaps are free from longitudinal threads, and transverse threads are joining edges with band-shaped web. During spiral winding of band-shaped web, first edge is placed within second gap and second edge is placed within first gap of adjacent coils for producing of continuous spiral seam formed by joining of adjacent coils together. Method allows wide web to be produced from relatively narrow band-shaped spiral-wound woven web.
EFFECT: increased efficiency and provision for producing of wide web for papermaking machine from narrow band-shaped webs.
