Abstract

A top cover (16) for use in a mat manufacturing process includes a substantially solid border portion (20) of heat resistant fabric having release properties and a vented central portion (22). The vented central portion (22) allows fumes evolved during the manufacturing process to escape before the operator removes the top cover, thereby reducing the operator's exposure to the fumes. For manufacturing a mat, a rubber backing sheet 10 is cured and heat-bonded under pressure to the back of a fabric layer 12 in a heated press (see Figure 1). During curing and bonding, the mat is covered with the top cover 16. The central portion includes at least one aperture formed by cutting out the central portion. Plural apertures are formed by cutting out portions of the central portion. At least one reinforcing element may extend across the central portion. The reinforcing element may comprise a woven mesh of reinforcing fibres.

Description

2352995 MAT MANUFACTURE This invention relates to the manufacture of mats,
rugs and carpets and particularly but not exclusively to a process for manufacturing mats, rugs and carpets in which a rubber backing sheet is cured and heat-bonded under pressure to the back of a fabric layer. It also relates to a top cover for use in a mat manufacturing process.
The invention is of particular utility in the manufacture of washable mats, such as dust control mats. Dust control mats are used at the entrances to buildings such as shops, factories and hospitals to remove dirt and moisture from the shoes of people entering the building. The term "washable" means washable by immersion and agitation in water or other cleaning fluid usually followed by spin extraction and tumble drying. The term "mat" is used hereinafter in a wide sense to include rugs and carpets.
In a typical mat manufacturing process, a natural or synthetic rubber backing sheet is cured and heat-bonded under pressure to the back of a fabric layer in a heated press. The rubber backing is normally slightly larger than the fabric layer to form a rubber border, typically about 2cm wide. Before the laid-up mat is placed in the press, it is covered with a top co ver of PTFE-coated woven glass. This top cover serves two purposes: it prevents the exposed rubber border sticking to the platen of the press and it imparts a woven fabric imprint to the border, enhancing its appearance.
During the heating and curing (vulcanising) process, the rubber backing is heated to a high temperature. This creates fumes, which are trapped under the top cover. When the mat is withdrawn from the press and the top cover is removed, these fumes are liberated into the atmosphere of the workplace. The finnes are unpleasant and, at high concentrations, can be hazardous to health. Ventilation equipment must therefore be provided to remove the fumes from the workplace.
It is an object of the present invention to provide a method of manufacturing mats and an apparatus for manufacturing mats that mitigates at least some of the aforesaid disadvantages. - 2 According to the present invention, there is provided a top cover for use in a mat manufacturing process, the top cover including a substantially solid border portion of heat resistant fabric having release properties, and a vented central portion.
The vented central portion allows fames evolved during the curing process to escape as soon as the pressure is released, while the mat is still within the confines the press. After completion of the curing and bonding process, the mat is held temporarily in the press and the press is ventilated to remove the fumes. Far less fumes are therefore released into the atmosphere of the workplace when the operator removes the cover. The operator's exposure to fumes is thus significantly reduced without the need for additional ventilating equipment.
Advantageously, the vented central portion includes at least one aperture formed in the cover. This may be formed very simply by cutting out the central portion of the top cove-r.
Advantageously, the top cover includes least one reinforcing element that extends across the vented central portion to provide dimensional stability to the cover, making it easier to handle. Preferably, the reinforcing element comprises a woven mesh of reinforcing fibres that extends across the vented central portion and is attached to the border portion of the cover.
Alternatively, a plurality ofapertures may be provided in the heat resistant fabric to form the vented central portion. These may be formed very simply by cutting out portions ofthe top cover. Preferably, the apertures are separated by strips of heat resistant fabric that extend across the vented central portion to provide dimensional stability to the cover, for easy handling. The strips of heat resistant fabric may form a square or rectangular lattice that extends across the vented central portion of the cover.
Advantageously, the heat resistant fabric comprises a PTFE-coated woven glass fabric.
According to a further aspect of the present invention, there is provided a mat manufacturing process in which a rubber backing sheet is cured and heat- bonded under pressure to the back of a fabric layer in a heated press wherein, during the curing and bonding process carried out in the heated press, the mat is covered with a top cover including a substantially solid border portion of heat resistant fabric having release 3 properties and a vented central portion.
The process allows fumes evolved during the curing process to escape as soon as the pressure is released, while the mat is still within the confines the press, thereby reducing the operator's exposure to the fumes.
Advantageously, the mat has a central fabric portion and an exposed rubber border that extends beyond the fabric portion, said exposed rubber border being covered during the curing and bonding process by the substantially solid border portion of the top cover, and said vented central portion being positioned over the fabric portion. The top cover thus prevents the exposed rubber border sticking to the platen of the press 10 and imparts a woven fabric imprint to the border, while allowing fumes evolved during the curing process to escape. Advantageously, after completion of the curing and bonding process, the mat is held temporarily in the press and the press is ventilated to remove furnes evolved during the process. 15 By way of example, embodiments of the invention will now be described with reference to the accompanying drawings, in which: Figure I is a schematic exploded cross-section of a mat laid up in a press; Figure 2 is a plan view of a prior art top cover; Figure 3 is a plan view of a top cover according to a first embodiment of the invention; 20 Figure 4 is a plan view of a top cover according to a second embodiment of the invention, and Figure 5 is a plan view of a top cover according to a third embodiment ofthe invention. In a typical mat manufacturing process, an uncured natural or synthetic rubber backing sheet is cured and heat-bonded under pressure to the back of a fabric layer in a heated press. The fabric layer typically consists ofa tufted nylon pile on a non-woven polyester substrate. The 25 rubber backing is normally slightly larger than the fabric layer to form a rubber border, which is typically about 2cm. wide. The rubber backing layer and the fabric layer are laid up on a non-stick release sheet, for example of PTFE-coated woven glass fabric, and are covered with a top cover, also of PTFE-coated woven glass. The mat is then placed in the press for the bonding and curing process. The top cover prevents the exposed rubber
4 border of the mat sticking to the platen of the press and imparts a woven fabric imprint to the border, enhancing its appearance.
Figure I is a schematic exploded cross-section of a laid up mat in a press. The press includes a heated metal platen 2 located above an inflatable diaphragm 4. The press also includes a ventilating system 6 for removing fumes 8 evolved during the curing process.
The laid up carpet, which consists of a rubber backing sheet 10 and a tufted fabric layer 12, is located between a bottom release sheet 14 and a top cover 16, both of PTFE-coated woven glass. The laid up carpet is placed in the press between the heated metal platen 2 and the inflatable diaphragm 4.
In some types of mat making press (not shown), the positions of the, metal platen and the diaphragm are reversed, the heated metal platen being located below the inflatable diaphragm. The present invention is equally applicable to both types of press.
The press is typically heated to a temperature of about 170'C. The diaphragm 4 is inflated, for example to a pressure of 30 pounds per square inch, pressing the mat against the heated platen 2 above for a cycle time of 20 minutes. When the positions of the metal platen and diaphragm are reversed, the cycle time is 6 minutes. The heat from the platen softens and cures the rubber backing 10, and the pressure from the diaphragm presses the fabric layer 12 into the rubber backing, bonding the two layers together.
As shown in figure 2, atypical prior art top cover 16 consists of a rectangle ofPTFE-coated woven glass fabric 18. The cover has dimensions of I 00cm x 165cm. and is normally used singly for mat sizes up to 85cm x 150cm. For larger mats, two or more overlapping top covers may be used. The cover is substantially impermeable to gas, with the result that any fumes evolved during vulcanisation are trapped beneath the cover until it is removed by an operator, when they are liberated into the atmosphere. The fumes are unpleasant and, at high concentrations, can be hazardous to health. Ventilation equipment must therefore be provided to remove the fumes from the workplace.
A top cover 16 according to a first embodiment of the invention is shown in figure 3. The cover is similar to the prior art cover shown in figure 2 in that it consists of a rectangle of
PTFE-coated woven glass fabric. However, unlike the prior art cover, the central part of the cover is removed to form a large rectangular aperture 22 in the centre of the cover. The mat therefore has a substantially solid border portion 20 and a vented central portion comprising the aperture 22. The aperture 22 is somewhat smaller than fabric layer, to ensure that the rubber border of the mat is fully covered and to allow easy placement of the cover. For example, on a typical 85cm x 150cm mat with a fabric layer measuring 82cm x 147cn-4 the cover will typicallyhave external dimensions of I 00cmx 165cmand the aperture in the cover may be approximately 70cm x 130cm.
In the mat manufacturing process, the mat is laid up on a bottom release sheet 14 and is covered with a top cover 16, which is positioned such that the exposed rubber border is covered by the substantially solid border portion 20 of the top cover, and the vented central portion 22 is located over the fabric portion. The rubber backing sheet is then cured and heat-bonded under pressure to the back of a fabric layer in the heated press.
The aperture 22 in the top cover 16 allows fumes evolved during the curing process to escape through the central vented portion as soon as the diaphragm 4 is evacuated, while the mat is still within the confines the press. After completion of the curing and bonding process, the mat is held temporarily in the press and the press is ventilated to remove the fumes. Far less fumes are therefore released into the atmosphere of the workplace when the operator removes the cover 16. The operator's exposure to fumes is thus significantly reduced without the need for more ventilating equipment.
A top cover 16 according to a second embodiment of the invention is shown in figure 4.
The cover is similar to that shown in figure 3 in that it consists of a rectangle of PTFE coated woven glass fabric with a substantially solid border portion 20 and a large central aperture 22. A reinforcing mesh 24, for example of woven glass or KEVLARTm or other suitable material is attached to the border region 20 of the cover and extends across the aperture 22 to improve the dimensional stability of the cover, making it easier to handle.
The open area of the mesh 24 is as large as possible to aid venting of the fumes. For example, the mesh may be of woven glass, the mesh size being 5mm squares and the fabric strands having a diameter of approximately 2mm.
It is not essential that mesh 24 is in the form depicted in figure 4: any gas permeable woven material would also work.
6 A top cover 16 according to a third embodiment of the invention is shown in figure 5. The cover is similar to that shown in figure 3 in that it consists of a rectangle of PTFE-coated woven glass fabric with a substantially solid border portion 20 and a vented central portion 22. The vented central portion 22 is created by cutting squares out of the cover to form a plurality of apertures 26. The squares measure 10 x 10cm and the strips of fabric 28 between adjacent squares are 5cm wide and form a square lattice that extends across the vented central portion. The open area of the vented portion is sufficient to allow fumes to escape and the strips provide dimensional stability, making the cover easy to handle. This embodiment has the advantage that it is very cheap to produce.
Various modifications ofthe apparatus and the process described above are possible, some of which are described below.
The top cover 16 may be made of any other suitable material that is heatresistant and has release properties, to prevent the rubber backing sticking to the heated platen.
The size and shape of the vented central area, and the number, size and shape of the vents provided in that area may be varied according to requirements. The open area should, however, be sufficient to aflow most of the fumes to escape while the mat is still within the confines of the press, so that they can be removed by the venting system of the press. The size and width of the border portion may also be varied, to suit the dimensions of the mat.
The process may also be used to produce rugs and carpets that are not intended for use specifically as dust control mats.
