Abstract
(EN)

A method and apparatus for forming spring units for use in a mattress, bed, divan bed, or other upholstered unit, the method including the step of inserting a second spring (12A) into a first spring immediately prior to said first spring being formed into a pocketted spring. The second spring (12A) may be formed into a pocketted spring prior to insertion into said first spring.

The apparatus includes means (4) for feeding a second spring (12A) to a composite spring forming station (6) immediately prior to a first spring being fed to said station, means to compress and rotate the formed composite spring (30) through substantially 90°, means to insert the composite spring into a sleeve of material, and means to form said composite spring and a portion of said sleeve into a pocketted spring unit.
