(EN) METHOD AND APPARATUS FOR FORMING SPRING UNITS
(FR) PROCEDE ET DISPOSITIF DE FORMATION D'UNITES A RESSORTS
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 immediately prior to a first spring being fed to said station, means to compress and rotate the formed composite spring 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.
(FR) L'invention concerne un procédé et un dispositif de formation d'unités à ressorts, utiles dans un matelas, un lit, un divan ou un autre article rembourré. Le procédé comprend l'étape consistant à insérer un second ressort (12A) dans un premier ressort, immédiatement avant la formation du premier ressort en ressort logé dans une poche. Il est possible de former le second ressort (12A) en un ressort logé dans une poche, préalablement à l'insertion de celui-ci dans le premier ressort. Le dispositif comporte des moyens (4) d'apport d'un second ressort (12A) vers un poste de formation de ressorts composés, immédiatement avant qu'un premier ressort ne soit dirigé vers ce poste, des moyens destinés à comprimer et à faire tourner d'environ 90° le ressort composé formé, des moyens d'insertion de ce ressort composé dans un manchon de matériau, ainsi que des moyens servant à former ce ressort composé et une portion dudit manchon en une unité à ressort logée dans une poche.
