Abstract: A process for personalizing a mounting plate of a plurality of layers of a mounting plate material and a plurality of layers of fibrous material layered over the layers of mounting plate material, which involves joining the fibrous material layers to the mounting plate material layers by penetrating a predetermined number of wick-like extensions of the fibrous material into the mounting plate material to a predetermined depth in the mounting plate material.

Abstract: Structured in modular fashion based on two sides (1-1'), a head (2) and a foot (2') standing as independent parts fixable by means of corner members (3), both the length and the width may be adjusted at will, by means of a greater or lesser degree of plugging or overlap of the corner members (3) with respect to the sides, head and foot (1-2). Furthermore, each side (1-1') has a pair of connecting rods (8) hinged thereto which are hinged at their top end to two bolsters (9) that form part of the mattress platform or base as such, said bolsters being also independent in respect of each other and having fluted fittings (11) on their inner face in which rigid or flexible crosspieces (12) making up the platform may be plugged to a greater or lesser extent, to adjust its width at will, said bolsters (9) moreover having telescopic terminals (10) at their ends that in turn permit the length of the platform to be adjusted.

Abstract: It is provided with a longitudinal bearing (2) mounted on a frame (1) and framed by two side, vertical and parallel guides (9) and (10), the position of the latter being adjustable in order for the spacing thereof to match the thickness of the spring carcass, which is hauled by a thruster (4) driven by a motor reducer (5) intermittently towards the working area of two stapling heads (12-12) where a retractable ram (15) receives the spring action directly and adjusts, in accordance with the latter's diameter, the position of the balance lever acting on the proximity detector that in turn controls the movement of the motor reducer (5) in order for each spring to duly face the stapling heads (12).

Abstract: A method and apparatus for sewing the perimeter seam of an upholstered or trimmed article whereby the article is positioned upon a table having a planar sliding surface and a sewing machine located adjacent one side of the table. The table is variably adjustable at an incline between 0 and 90 degrees relative to horizontal so that when an article is placed on the planar surface, normal gravitational forces acting on the article force that article towards the sewing machine thereby facilitating the handling and introduction of the article to the sewing machine.

Abstract: A method for handling and sewing the perimeter of upholstered articles, in which the upholstered article is fed through the sewing machine on a table with a sliding surface in one of whose sides the said sewing machine is fixed, which is characterized by having some pusher elements which protrude from the plane of the table through some longitudinal and circumference arch shaped grooves, which are driven from the lower part of said table. The longitudinal pushers assist the linear feed of the upholstered article until its corner reaches the height of the sewing machine, when they withdraw to their initial position, at the same time as the turning pushers start to work. These turning pushers make the upholstered article turn, describing a circumference arch path of ninety degrees, while the head of said sewing machine sews the corner of said upholstered article in a synchronized manner.

Abstract: Apparatus and a concomitant method for sewing seams in upholstered furniture such as mattresses. The apparatus contains a sewing machine located adjacent a conveyor belt which moves the mattress in a linear direction beneath the sewing machine, a presser arm for turning the mattress, and a fastening cylinder for temporarily attaching the mattress to the presser arm during the turning process. A single motor drives the sewing machine, the conveyor belt and the presser arm. As the mattress is moved by the conveyor belt at a first speed, the sewing machine sews a linear portion of a seam in the mattress. A sensor indicates when a corner of the mattress approaches the sewing machine. When the sensor indicates the approach of the corner, the conveyor belt is halted and the motor changes to a slower speed such that the sewing speed is slowed. Simultaneously, the fastening cylinder temporarily attaches a presser arm to the mattress.

Abstract: The mattress assembly installation has a number of mattress padding material spools for supplying separate mattress padding materials. These materials are received and superposed in a receiving stage downstream of the spools. The mattress padding material portion is cut at a cutting station from the supply of materials. Subsequently, or at the same time, a gluing apparatus, which may be part of the cutting apparatus, deposits strips of adhesive on the superposed mattress padding materials. The materials are conveyed to a folding station where at the materials are folding above a spring frame together with an inverted mattress covering. A robot or a carriage is provided for moving, inverting and removing the spring frame from the folding station.

Abstract: A device for securing slats to the frame of a bedspring comprised of a support partially encircling the end section of the slat and continuing in two straight sections longitudinal thereto, which constitute joining means to the frame since they are introduced in the holes of the inner wall thereof. The straight sections of the support are secured in a ferrule of the slat, in the bottom of which there has previously been placed damper means which absorbs the pressure of the slat. The slats constituting the support base for the mattress can have different widths, depending on the weight to be supported, according to their location, thereby reinforcing the corresponding zones.
