Abstract (en)
[origin: WO2015004154A1] The invention relates to a method for producing a pocket spring core consisting of multiple interconnected spring coils (1) each having a plurality of individual helical springs (4) arranged one behind the other and encased in a pocket, wherein at least some of the spring coils (1) are made of at least two partial spring coils (2, 3) abutting each other at their end faces. According to said method, to form a spring coil (1) made of partial spring coils (2, 3), said partial coils (2, 3), in the position in which their end faces point towards each other relative to the longitudinal axes of their individual springs (4), are together progressively synchronously joined and interconnected.
