ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a machine for cutting cloth and for applying borders and a peripheral band to cloths used to manufacture spring mattresses.
It is known (see in particular
FIGS. 1
,
2
and
3
) that a spring mattress is constituted by a rectangular prism-like metallic body
1
which is composed of a plurality of biconical springs
2
which are connected one another and are covered by one or more layers
2
a
of insulating material such as felt, foamed rubber and the like.
The upper and lower faces of the body
1
are covered by two rectangular cloths or quilts
3
and
4
whose edges are joined by a band
5
which peripherally closes the mattress.
Each cloth or quilt
3
and
4
is constituted, for example, by a panel
6
of soft material which is covered above and below by sheets of fabric
7
,
7
a
or the like, the panel and the sheets being joined by a more or less ornamental quilting. A band
10
is fixed to the inner edges of the quilts
3
and
4
by means of two parallel stitch lines
8
and
9
, so as to form a flap
11
which protrudes from the stitch lines
9
and is thus spaced from the stitch line
8
.
When the quilts
3
and
4
are applied to the opposite faces of the body
1
, the flaps
11
are first folded outwards and then under the first turn
12
of the springs
2
and finally fixed thereto with metal staples
13
.
In this manner, the quilts
3
and
4
are fixed to the body
1
, while their borders between the stitch lines
8
and
9
remain free so that they can be connected to the peripheral band
5
by an operation for final application of a border for closure, as shown in FIG.
3
.
Currently, the band
10
is fixed to the quilts
3
and
4
manually, at high cost, also because it requires additional operations for positioning and trimming the cloths or quilts.
SUMMARY OF THE INVENTION
The aim of the present invention is to provide a machine which allows to apply a peripheral band while the cloths are being cut and a border is being applied thereto.
Within this aim, an object of the present invention is to provide a machine which can be combined with an apparatus for forming a quilt constituted by one or more sheets unwound continuously from rolls.
This and other objects are achieved with a machine whose characteristics are defined in the appended claims.
