Abstract: Described is a roller for the automatic application of at least one adhesive on a sheet for mattresses, which makes it possible to optimise the time needed for processing and the precision of the distribution of adhesive on the sheet in relation to the desired pattern, eliminating the waste of adhesive.

Abstract: Described is a device (10) for applying an adhesive (C). The device (10) comprises at least one rotary gluing member (21, 31) designed to transfer to a mass of adhesive (C) towards a surface to be glued (S) and a plurality of rotating distributor members (51a-g) susceptible to being interposed, in operation, between the gluing members (21, 31) and the surface to be glued (S). The plurality of distributor members (51a-g) comprises a first portion of distributor members (51b, 51d, 51f) susceptible to make contact with the gluing member (21, 31) and a second portion of distributor members (51a, 51c, 51e, 51g) susceptible to remaining spaced from the gluing member (21, 31).

Abstract: A machine for recycling quilts includes an infeed station, configured to receive as input a quilt consisting of a plurality of layers joined by stitching, a heating station, including heating means configured to increase the temperature of the stitching to a change of state or softening temperature of a heat-sensitive sewing thread, a separating station, comprising traction means, acting on the plurality of layers for moving them in respective diverging directions.

Abstract: Described is a recyclable quilt including an upper layer, a lower layer, a padding interposed between the two layers and a stitching which passes through the two upper and lower layers for a mutual joining together. The stitching comprises at least one heat-sensitive sewing thread which has a temperature of change of state or softening which is lower than the temperatures of degradation of the above-mentioned layers and of the padding, in such a way that a change of state or softening of the heat-sensitive sewing thread causes the break-up of the stitching.

Abstract: Described is a machine for packaging mattresses comprising first movement means configured to move a mattress being processed along a first movement path and in a first feed direction and second movement means configured to move a functional layer along a second movement path and in a second feed direction. The second movement path is located at least partly above the first movement path until leading into it at a placement station, wherein the functional layer is placed on the mattress being processed. Means for applying adhesive material are positioned along the first movement path and detection means are configured and programmed to detect the position and preferably the dimensions of the mattress being processed and/or of the functional layer. The control unit is programmed to receive a detection signal indicating the position and preferably the dimensions detected and to generate a control signal of the first and/or second movement means.
