摘要:
A procedure is described for manufacturing a mattress with a padded mattress panel and a gusset, by means of which a quilted outer mattress panel (1') is prepared with a gusset (14) attached to its underside around its whole perimeter, and a seam (15) attaches the upper part of the gusset to the mattress panel, passing through both the panel and the gusset, so that the seam is visible on the outer side, forming a contour around the mattress panel and making the perimeter of the mattress panel curve upwards.
摘要:
A method and apparatus for forming a partial mattress sack which prevents radial bunching of the mattress. The method includes the steps of feeding first (206) and second (205) panels having different edge lengths at different rates through a sewing machine to form the partial mattress sack. The apparatus includes a variable speed upper walking foot (320) having an automatic speed adjustment (352).
摘要:
A device for positioning and joining at an angle, by means of a sewing machine, the edges of two flaps of fabric (P, F), particularly of a horizontal sheet and of a vertical band for forming a mattress case, said device comprising a first guiding wall (17a) for the edge of the sheet (P) and a second guiding wall (17b) for the edge of the band (F), said walls forming mutually adjacent cylindrical sectors (17, 18), two advancement elements being further provided which comprise rotating heads (6, 7) accommodated within cavities formed by said walls, said walls being movable between a position in which said rotating heads tangentially engage the edges of said sheet and said band on said walls in order to advance said edges toward a sewing region and a position in which said walls allow said heads to disengage from said walls.

摘要:
The invention pertains to a device for manufacturing three-dimensional covers. This device has a support body (4) to hold cuts (6) of material of preferably low flexural strength, the cut (6) being detachably mounted on the support body (4), which has at least one holding unit (16) with a holding element (26) whose range of engagement extends from a neutral position inside the support body to an operating position outside the support body.
摘要:
To form three-dimensional covers from at least two cuts (11, 13) to be sewn together, the first cut (11) is fitted to a first supporting surface of a bearer (13) in such a way that its edge projects beyond the bearer. A second cut (13) is then applied to a second supporting surface of the bearer (14), the edges (11a, 13a) of both cuts standing obliquely away from the cuts and forming an edge strip standing off the bearer (14). A sewing machine is taken along the base line (57) formed by the bend lines of the edges (11a, 13a) to produce a seam joining the cuts (11, 13) at that point.
摘要:
Verfahren für die Handhabung und das perimetrische Nähen von tapezierten Gesamtheiten, in dem das tapezierte Stück (1) durch die Nähmaschine (6) auf einem Tisch (2) mit Gleitfläche geleitet wird, wobei die besagte Nähmaschine an einer seiner Seiten fest ansitzt, dadurch gekennzeichnet, daß man über Schubelemente (3,7) verfügt, die über Längsschlitze (4) und in Kreisbogenform (8) aus der Tischfläche hervorragen und die vom unteren Teil des besagten Tisches (2) aus betätigt werden. Die Längsstöße (3) ermöglichen den linearen Vorschub des tapezierten Stücks, bis dessen Eckkante die Höhe der Nähmaschine erreicht hat und ihr somit gegenüberliegt. Anschließend fahren diese in ihre Anfangsstellung zurück und gleichzeitig werden die Drehstößel (7) in Betrieb gesetzt. Diese letzteren drehen das tapezierte Stück in einer Kreisbogenlinie von ungefähr neunzig Grad, während der Kopf der besagten Nähmaschine die Ecke des besagten tapezierten Stücks auf gleichmäßig verlaufende Art und Weise näht. Sobald die Drehung beendet ist, fahren die Stößel in ihre Anfangsstellung zurück und die vorhergehenden Längsstößel setzen sich erneut in Betrieb.
