A spring interior forming method and apparatus (30, 30a, 50, 80) provides a spring interior assembler (35, 35a, 55) and a coil row transfer station (40, 40a, 52) upstream of the assembler having at least one conveyor (35, 35a, 51) extending therethrough. A coil former (31, 31a, 31b, 56a, 56b) is provided at an upstream end of the conveyor and is operated through a plurality of cycles, each to feed one spring coil (32, 32a, 32b, 54a, 54b) onto the conveyor. Between consecutive cycles of the feeding of a spring onto the transfer conveyor (51), a stepper motor (53) or other servo-type motor advances the conveyor (51) a programmed distance, thereby providing the capability for obtaining different programmed spacings between coils on the rows presented by the transfer conveyor (51) to the transfer station (52).
Méthode et appareil de mise en forme d'intérieur de ressort (30, 30a, 50, 80) comprenant un assembleur d'intérieur de ressort (35, 35a, 55) et un poste de transfert de rangées de spires (40, 40a, 52) placé en amont de l'assembleur et possédant au moins une bande transporteuse (35, 35a, 51) sur toute sa longueur intérieure. Un formeur de spires (31, 31a, 31b, 56a, 56b) est placé à une extrémité en amont de la bande transporteuse et fonctionne sur plusieurs cycles, chaque cycle devant placer une spire de ressort (32, 32a, 32b, 54a, 54b) sur la bande transporteuse. Entre chaque cycle consécutif de mise en place d'un ressort sur la bande transporteuse (51), un moteur pas-à-pas (53), ou un autre moteur de type à servodirection, fait avancer la bande transporteuse (51) sur une distance préprogrammée permettant ainsi d'obtenir différents espacements programmés entre les spires sur les rangées amenées par la bande transporteuse (51) au poste de transfert (52).
