The endless belt according to the invention is intended for instance to fit the shrinkage station of a machine for shrinking fabrics.
Description
ENDLESS BELT AND MACHINE FOR SHRINKING FABRICS
The subject matter of the present invention essentially is an endless belt co-operating with at least one cylinder for shrinking a sheet material such as, for instance, fabric or paper, interposed between the belt and the cylinder.
It is also directed to a machine fitted with this belt for shrinking fabrics and other materials.
There are known long since machines for shrinking fabrics in particular comprising a shrinking station where the fabric is driven by passing between a heating cylinder and an endless belt forming in a way a sleeve passing around a plurality of rolls and driving the fabric which may slide onto the heating cylinder.
However the belts or sleeves used heretofore in shrinking machines of the kind referred to above were made from a single material and in particular exhibited the inconvenience of allowing only a limited shrinkage of the fabric, i.e. a shrinkage which may not exceed a certain threshold, which may be disadvantageous for certain types of fabric requiring a great shrinkage.
Therefore the object of the present invention is to cope with these inconveniences by proposing an improved endless belt capable of imparting to the fabric or other sheet material a much greater shrinkage than that provided by the known endless belts.
In one aspect of the invention, there is provided an endless belt adapted to cooperate with at least one cylinder for shrinking a sheet material (T) wherein said sheet material comprises fabric, paper or other material, interposed between the belt and the cylinder, and wherein said material is under the effect of a change in curvature of the belt driving this material, wherein the said belt is made from at least two elastomer materials one of which constitutes the thickness fraction of the belt towards the sheet material (T) and is more flexible than the other material constituting the other thickness fraction or remaining thickness of the said belt so as to impart to the latter differential elasticity properties adapted to the material to be shrunken, characterized in that the thickness fraction, and the remaining thickness of the said belt are made from elastomer materials each having a different modulus of elasticity within a range between about 0.1 and 10 MPa.
In a second aspect, there is provided a machine for shrinking fabrics or other materials comprising a shrinkage station with an endless belt driving the fabric (T) and cooperating with a heating cylinder, characterized in that the said endless belt is a belt according to the first aspect.
In a third aspect, there is provided a machine for shrinking fabrics comprising: a shrinkage cylinder and an endless belt comprising inner and outer elastomer layers having a different modulus of elasticity between 0.1 and 10 MPa, said inner elastomeric layer disposed around three spaced-apart mounting cylinders and said outer elastomeric layer disposed against said shrinkage cylinder and having a greater modulus of elasticity than said inner elastomeric belt layer and forming a convex curvature in said belt against said shrinkage cylinder whereby a sheet of fabric, when introduced between said belt and cylinder when rotating together is shrunken by the differential elasticity properties of said inner and outer elastomer belt layers against said shrinkage cylinder.
In a fourth aspect, there is provided a machine for shrinking sheet materials comprising: a rotatably mounted shrinkage cylinder and an endless rotatably mounted belt comprising inner and outer elastomer layers having a modulus of elasticity in the range of 0.1 to 10 MPa, said outer elastomer layer disposed against said shrinkage cylinder to form a convex curvature to sheet material introduced between said cylinder and belt, said outer elastomer layer having a greater modulus of elasticity than said inner elastomer layer and thereby having a greater deformation than said inner layer when said outer layer is disposed against said rotatably mounted shrinkage cylinder, whereby a sheet material introduced within the convex curvature is shrunken.
Preferably a core material, possibly reinforced with fibres, is provided between the two thickness fractions of the belt.
Preferably the thickness of each of the thickness fractions of the belt is between about 1 and 50 mm whereas the thickness of the core is between about 0 and 50 mm.
2a It should further be specified here that this belt may comprise an embossing such as notches, goffers, grooves or the like on its surface opposite to that in engagement with the sheet material.
Now further characteristics and advantages of the invention will better appear in the detailed description which follows, with reference to the annexed drawings, given by way of example only, and wherein:
- Figure 1 is a diagrammatic elevational view of a machine for shrinking fabrics in particular comprising a shrinkage station fitted with a belt according to the invention; and -Figure 2 is a cross-sectional view of this belt.
On Figure 1 is seen a machine known per se permitting the shrinkage through compression of fabrics, i.e. the squeezing of the weft and warp threads to provide in a way for a blocking of the fabric. 'Thus the fabric acquires a very great dimensional stability characterized by a permanent state and maintenance of this shape and of the size of the article made with this fabric.
The fabric exhibits the shape of a web designated at T on Figure 1 and is at first moistened at she station 1 b:y steam and/or by water sprayed by nozzles or the like 2.
The fabric then passes onto a device 3 of a type known per se imparting to the fabric web T a constant width and adapted to allow the said web to pass into a shrinkage si~ation generally designated at 23.
'This shrinkage station essentially comprises a heating cylinder 4 co-operating as shown with a sleeve-like endless belt 5 passing around three rolls 6, 7 and 8. The fabric web T passes between the heating c:ylind.er 4 and the sleeve 5 which with its outer surface 5a drives the said web which may slide onto the periphery of the cylinder 4. More specifically the sleeve 5 rotates about the heating cylinder 4 while being guided by the rolls 6, 7 arad 8 which are bending it:s path of travel. The fabric input roll 6 is operable by a pressurizing system (not: shown) which applies the sleeve: 5 against the cylinder 4. The roll 8 placed at the exit of the fabric web T from the shrinkage station 23 is disengaged from the cylinder 4 and allows the adjustment in tension of the sleeve 5 during use. A.t last the intermediate roll 7 is positioned in the lower portion of the shrinkage station 23 as well seen on Figure 1.
As is understood the fabric web T is driven at the point of compression P of t:he intake roll 6 between the outer surface 5a of the sleeve 5 and the periphery of the heating cylinder 4. It is there, i.e. beyond 'the compression point P where the shrinkage of the fabric is effected in view of the reversal of the curvature of the sleeve 5. It is seen indeed on Figure 1 that 'the outer surface 5a of the fabric web T above the inlet roll 6 is convex-curved whereas it is concave-curved beyond the point P so that the fabric clinging to the surface 5a will shrink itself at this place on account of the "elastic shrinkage"
generated by the concave shaping of the outer :surface 5a of the sleeve 5.
The advancing of the fabric between this sleeve 5 and the heated cylinder 4 will provide fo:r a f:Lrst fixing of the new arrangement of the warp and weft threads of the previously shrunken fabric.
The fabric web T then leaves tree shrinkage station 23 to reach a calandering station 9 which allows the fabric web to dry and especially to complete its fixing and therefore to freeze the shrunken arrangerr~ent of the warp and weft threads of the web of fabric.
Reverting to the shrinkage station 23 it is important to note here that the shrinkage induced by the change in curvature of the sleeve as previously explained is limited and may not go beyond a certain threshold in view of the fact that the sleeve 5 is made from a single material.
According to the invention and as seen on Figure 2 the endless belt or sleeve 5 is made from two .materials one of which is more flexible than the other one. More specifically the thickness fraction or layer 10 of the belt 5 located towards the web of fabric or any other similar material and therefore comprising the outer surface 5a previously mentioned is more flexible than the other material constituting the other thickness fraction or layer 11 forming in a way the :inner surface of the belt or sleeve 5.
Although this is not compulsory it is possible to provide between both thickness fractions or layers 10, 11 an a~~ditional material forming the core of the belt 5, which c~~re may possibly be reinforced with fibres.
Both layers 10, 11 are made from an E~lastomer therefore having a different roodulus of elasticity which may l:ie between 0.1 and 10 MPa.
'The thickness of both layers 10, 11 rnay be variable in accordance with the nature of the fabric to be processed and may lie between for instance 1 and 50 mm.
If the core 12 is present its thickness may lie in a range between about 0 and 50 mm.
Also the inner layer 11 of the sleeve 5 may comprise embossings forming for instance notches, goffers, grooves or the like on its surface lla opposite to the outer surface 5a. in engagement with the fabz°ic or the like T as diagrammatically shown at 7.3. Thus will be advantageously achieved a good clinging of the sleeve or of the belt 5 onto the rolls 6, 7 and 8 which may but improve the effectiveness of the shrinkage station 23.
But it is especially important to note that owing to the provision of two layers or thicknesses 10, 11 of differing flexibilities for the belt 5, this belt will have differential elasticity properties adapted to 'the sheet material such as fabric, paper or the .like which is desired to be shrunken.
More specifically when the belt or sleeve 5 makes a curve a greater deformation of the outer sur:Eace 5a of the layer 10 will be obtained owing to the fact that the layer 10 is associated with a :Layer 11 which is harder whereas if as in the prior art the sleeve is made from a aingle material a less greater deformation of the outf=r surface 5a in the curves would be achieved.
This means that with the sleeve according to the invention for a given length of fabric passing onto the intake roll 6 of the shrinkage station 23 there will be obtained after the compression point P, i.e. at the change in curvature of the sleeve a shrinkage of i~he fabric which together with the sleeve according to the invention is definitely superior to that which would be obtained with a i'8549-5 sleeve made from a single material according to the prior art.
The magnitude of the shrinkage an the fabric depends on the thicknesses and relative maduli of elasticity of both layers or thickness fractions 10, 11 of the sleeve.
It should be understood that the invention is not at all limited to the embodiment described and illustrated which has been given by way of example only.
Thus the core 12 of the sleeve 5 could be present or absent and the thicknesses or the different moduli of elasticity of bath layers 7.0 and 11 may be of any value whatsoever and adapted to the sheet materials such as fabrics, papers or the like which desirably are 'to be shrunken.
This means that the invention comprises all the technical equivalents of the means described as well as their combinations if the latter are carried out according to its gist.
The subject matter of the present invention essentially is an endless belt co-operating with at least one cylinder for shrinking a sheet material such as, for instance, fabric or paper, interposed between the belt and the cylinder.
It is also directed to a machine fitted with this belt for shrinking fabrics and other materials.
