Abstract
With the carcass of a mattress or with the aid of a template and the use of beaders, the cover or sheath is formed with transit and dwelles; on at least a loading bench; in at least a first beader, in order to bead a perimetral valance to a sheath bottom; in at least an overturning device; in at least a second beader; on at least a bench for the unloading and possible withdrawal of template.
Claims9
An apparatus for the semi-automatic manufacture of sheath-form covers for mattresses including a first series of work stations arranged sequentially to provide a first workpiece feed path having workpiece entry and exit ends comprising:
- a first loading bench at the entry end for receiving a mattress template and the workpiece, comprising an annular band for the formation of the side of the cover and one of two main fronts of the cover;
- a first beader adjacent said loading bench, for beading said annular band to said one main front of the cover along perimetrical edges thereof;
- first transfer means operable to extend between the first loading bench and the first beader for transferring said template from said loading bench to said first beader;
- a first unloading bench and a second loading bench adjacent the first unloading bench;
- an overturning device connected between said first unloading bench and said second loading bench, said overturning device having two sets of arms operable to engage respective opposite sides of the template and to remove the template from said first unloading bench overturn and deposit the template in overturned condition on said second loading bench;
- second transfer means operable to extend between the first beader and the first unloading bench for transferring said template from said first beader to said first unloading bench;
- a second beader adjacent said second loading bench;
- third transfer means operable to extend between the second loading bench and the second beader for transferring said template from said second loading bench to said second beader;
- a second unloading bench at the exit end of the feed path including means for withdrawing the template from the cover formed thereon;
- and,
- fourth transfer means operable to extend between the second unloading bench and the second beader for transferring said template from said second beader to said second unloading bench.

- a first loading bench at the entry end for receiving a mattress template and the workpiece comprising an annular band for the formation of the side of the mattress carcass and one of two main fronts of the mattress carcass;
- a first beader adjacent said loading bench, for beading said annular band to said one main front of the cover along perimetrical edges thereof;
- first transfer means operable to extend between the first loading bench and the first beader for transferring said carcass from said loading bench to said first beader;
- a first unloading bench and a second loading bench adjacent the first unloading bench and an overturning device connected between said first unloading bench and said second loading bench, said overturning device having two sets of arms operable to engage respective opposite sides of the carcass and operable to remove the carcass from said first unloading bench overturn and deposit the carcass in overturned condition on said second loading bench;
- second transfer means operable to extend between the first beader and the first unloading bench for transferring said carcass from said first beader to said first unloading bench;
- a second beader adjacent said second loading bench;
- third transfer means operable to extend between the second loading bench and the second beader for transferring said carcass from said second loading bench to said second beader;
- said second beader being operable to bead a second main front to said annular band along perimetrical edges;
- and,
- a bench at the exit end of the feed path arranged to receive the mattress carcass with the cover formed thereon from the second beader;
- fourth transfer means operable to extend between the second unloading bench and the second beader for transferring said template from said second beader to said second unloading bench.
