Mattress and machine for its production

Abstract

A mattress comprising an outer case made of a material substantially of the textile type for an internal block made of deformable material. The mattress comprises, along at least one portion of a perimetric lateral band of the case, at least one ribbon, which is stably associated with the respective portion, along connecting lines which are not parallel to the longitudinal axis of the ribbon. Between the ribbon, the portion of the perimetric lateral band of the case and the connecting lines there is at least one seat which is adapted to accommodate respective grip elements, including the fingers of an operator, during the transport of the mattress.

1 . A mattress of the type comprising an outer case made of a material substantially of the textile type for an internal block made of deformable material, comprising, along at least one portion of a perimetric lateral band of said case, at least one ribbon, which is stably associated with said portion along connecting lines which are not parallel to a longitudinal axis of said ribbon, between said ribbon, said portion of the perimetric lateral band of said case and said connecting lines at least one seat being defined which is adapted to accommodate respective gripping means, including fingers of an operator, during transport of said mattress, wherein said ribbon is stably coupled to said perimetric lateral band of said case by means of a further auxiliary connecting line, an orientation and direction of which are substantially parallel to the longitudinal axis of said ribbon, between said ribbon, said portion of the perimetric lateral band of said case, said connecting lines which are not parallel to the longitudinal axis of said ribbon and said auxiliary connecting line, said at least one seat being defined with a shape of the type of a pocket which has a single opening adapted for the insertion and accommodation of respective grip means during the transport of said mattress. 
     
     
         2 . The mattress according to  claim 1 , wherein said ribbons are two in number, arranged substantially along the edges of said perimetric lateral band, substantially proximate to the edges of the case at which there is a connection between said perimetric lateral band and one of the two larger faces of said mattress. 
     
     
         3 . The mattress according to  claim 1 , wherein the connecting lines that are not parallel to the longitudinal axis of said ribbon delimit said seat laterally. 
     
     
         4 . (canceled) 
     
     
         5 . The mattress according to  claim 1 , wherein the pocket-shaped seats of the two ribbons that face each other and are stably associated with said perimetric lateral band of said outer case are mutually aligned and arranged so that the respective openings and inner cavities face each other. 
     
     
         6 . The mattress according to  claim 1 , wherein said connecting lines that are not parallel to the longitudinal axis of said ribbon and said additional auxiliary connecting line are lines of stitches, said lines of stitches having a pattern selected from linear, curvilinear, mixed, zigzag and according to a particular decorative design. 
     
     
         7 . A machine for providing a mattress, of the type comprising a fixed frame designed to support a sliding surface for portions of laminar material to be sewn together, comprising at least two sewing heads which are integral with a respective support, arranged substantially in a cantilever manner on said sliding surface and integral with said fixed frame, the active tab, provided with at least one element of the type of a needle, of each head being translationally moveable on command along at least one predefined direction with respect to said sliding surface. 
     
     
         8 . The machine according to  claim 7 , wherein said two heads are identical, are arranged parallel to each other and are mounted on respective supports of different lengths, which are connected to the same side of the frame with respect to said sliding surface, for the substantial transverse alignment of the respective active tabs with a portion of said sliding surface that is proximate to its lateral edges, with a longitudinal offset equal to the center distance between the two heads. 
     
     
         9 . The machine according to  claim 7 , wherein said heads are identical, are arranged along incident directions and are mounted on respective supports which are connected to opposite sides of the frame with respect to said sliding surface, for the substantial alignment of the respective active tabs with a portion of said sliding surface that is proximate to the lateral edges thereof. 
     
     
         10 . The machine according to  claim 7 , wherein said two heads are symmetrical with respect to a longitudinal plane, are mutually aligned with respect to said longitudinal plane and are mounted on respective supports, which are associated with opposite sides of the frame with respect to said sliding surface, for the substantial alignment of the respective active tabs with a portion of said sliding surface that is proximate to the lateral edges thereof.
