Description

FABRIC WEAVE
ON FLEXIBLE PLASTIC TUBING
FIELD OF INVENTION
The present invention relates to the field of fabric weaving on the flexible plastic tubing that is embedded with or without a wire conductor. More particularly, the invention relates to fabric weaving on a flexible plastic tubing extruded out from an extruder.
BACKGROUND OF THE INVENTION
PCT/SG2019/050182 disclosed an Apparatus and Method for making flexible tubing that is embedded with a wire conductor.
For this PCT/SG2019/050182 patent, it disclosed a method of manufacturing the flexible tubing whereby the electrically conductive wires are extruded directly inside the extruder together with the polymeric resin instead of having it done separately outside as described in the current prior art. This PCT/SG2019/050182 patent aims to solve some of the quality issues associated with those in the prior art. It consists of an extruded profile that is overlapping the plastic ribbon in which the profile consists of at least one or more electrically heated conductor or conductive wires. The plastic ribbon itself is helically wrapped such that its edges overlap and is simultaneously heat-bonded together to form the wall of the flexible tubing As the flexible tubing from the PCT/SG2019/050182 patent is a form of tubing that is made of polymeric resin, sometimes it is desirable to have a layer of fabric or fabric-like textile material weaved on it. In the current commercial market, there is no fabric tube that is air-sealed, flexible and stretchable. Here we disclosed an industrial process to fabricate the above-mentioned product in one continuous process. Fabric or fabric-like textile material are used for the following reasons, namely their mechanical properties such as elongation, shrinkage, tear strength, extensibility, etc. can be adjusted accordingly to the required applications and properties. Having a fabric-like material such as a nylon coming into contact with the human skin can provide some added benefits. Such fabric-like materials serve to provide the required softness and comfort to the human skin which is hard to be replicated on a polymeric material (such as plastic). Moreover, the fabric-like materials exhibit other properties such as good abrasion resistance, good crease resistance and tear strength, yet comfortable and offer infinite aesthetics opportunities.
Fabric-like materials or fabric-like textile materials can be woven onto the flexible heated tubing. The present invention consists of a horizontal extruder machine that will fabricate a flexible plastic tubing with or without conductive wires, and a vertical weaving machine with specially formulated yarn, with customized jigs and fixtures that includes a pulley system and a conveyor system. The present invention disclosed here involves having the fabric to be woven on the flexible heated tubing that is being extruded out as disclosed out in the patent PCT/5G2019/050182. Besides flexible heated tubing, the fabric can also be woven on any flexible tubing that does not have any heated electrical conductor present inside.
The fabric weaving machine being disclosed in the present invention is a vertical-mounted weaving machine that is set up to be placed next to the extrusion machine, with a multitude of yarn ends which are interwoven around the weaving ring area in the weaving machine For horizontal-mounted weaving machine, the difference (as compared to vertical-mounted weaving machine) is that it has different machinery configuration and has the possibility of taking up slightly more floor area as compared to a vertical-mounted weaving machine. There are also other components within the weaving machine but it varies depending on the machine design and configuration being utilised for this present invention.
There is a smart control system with sensors that links both the extruder and the weaving machine to the Manufacturing Execution System (MES), whereby it receives and integrates control parameters from the weaving machine and from the extruder control panel, processes and analyses the information in order for the extruder and the weaving machine to be operating effectively. Output data collected from the MES will be collated and analysed in order to enhance the fabric weaving operation. Moreover, if either the weaving machine or the extruder is being stopped intentionally or if there is a malfunction, the sensor will then send a signal to the control unit so that it will then enable the weaving machine and/or the extruder to be shut down or stop operating. Hence this means that the control unit also acts like a safety device for the operator/user.
Once the flexible tubing is extruded out from the extruder, the tubing is then cooled sufficiently on a cooling water bath, followed by a dryer before having it fed into the vertical weaving machine that is being placed just next to the extruder. This feeding can be done manually or automated via conveyor means for mass production. The vertical weaving machine will then perform fabric weaving on the extruded flexible tubing by continuously inter-weaving the yarn ends of the fabric on the flexible tubing. Concurrently the tube is then vertically pulled upwards as it is being weaved with fabric. The different fabric weave or design will also depend on how the yarn ends are interlaced. To pull the fabric weaved extruded tube upwards, there are special pulleys cum conveyors means to facilitate the weaved tube to be pulled vertically upwards after weaving and then have it transported (via conveyor) to the cutting station in order to have the tubes cut out accordingly depending on the project requirement and design. The cut-out fabric tubes will then be sent for quality control inspections in order to ensure good quality fabric tubes are being produced during the mass production. The entire process is then repeated and is also fully automated.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT OF THE PRESENT
INVENTION
In the following description, details are provided to describe the embodiment of the application.
The present invention here relates to the field of fabric weaving on an extruded flexible plastic tubing that is embedded with or without a wire conductor.
Figure 1 illustrates an overall perspective view of the various key components and functions for the embodiment of the present invention. It illustrates an extruder portion 1, whereby the flexible tubing 2 is extruded out from the die of the extruder 1, and it has no fabric being weaved at this stage. For the extruded flexible tubing 1, it can be embedded with either a conductive or non-conductive wire depending on the application. The extruded flexible tubing 2, which is still hot while freshly extruded out, is then fed onto a conveyor belt system that leads to a cooling water bath cum dryer 3 so that the extruded flexible tubing 2 can be cooled down and dried sufficiently. Next to the cooling water bath cum dryer 3 is a fabric weaving machine 4 that has winding rolls to facilitate the movement and feeding of the flexible tubing 2 for the weaving process. There is a range of different fabric yarn 5 located on the yarn stand as illustrated in Figure 1. During weaving, the fabric weaving machine 4 has a multitude of yarn ends, which are then continuously inter-woven via thread form 6 onto the flexible tubing 2 so that the flexible tube has a layer of woven fabric 6 on it.
There is a smart control system that links both the extruder 1 and the fabric weaving machine 4 to a Manufacturing Execution System (MES), whereby it receives and integrates control parameters from the fabric weaving machine 4 and from the extruder control panel. Upon receiving the control parameters, the control unit then processes and analyses the information in order for the extruder 'I and the weaving machine 4 to be operating effectively. Output data collected from the MES will be collated and analysed in order to enhance the fabric weaving operation. Moreover, if either the weaving machine or the extruder is being stopped intentionally or if there is a malfunction, the sensor will then send a signal to the control unit so that it will then enable the weaving machine 4 and/or the extruder 'I to be shut down or stop operating. Hence this means that the control unit also acts like a safety device for the operator/user.
As illustrated in Figure 'I, the tubing 2 is then vertically pulled upwards as it is being fabric woven through the weaving machine 4. Once it is out from the weaving machine 4, it has fabric weaved onto it to become fabric weaved tubing 8. There is special pulley system installed within the weaving machine 4 in order to facilitate the fabric woven tube to be pulled vertically upwards after weaving and then followed by having it transported via a combination of pulley (on the weaving machine side) and conveyor belt system 7. This fabric woven flexible tubing 8 is then transported (via conveyor belt system 7) to a separate cutting station 9 in order to have the tubes cut out accordingly depending on the project requirement and design. The cut-out fabric tubes will then be sent for quality control inspections in order to ensure good quality fabric tubes are being produced during the mass production.
While what has been described hereinabove is the preferred embodiment of the invention, those skilled in the art will understand that numerous modifications may be made without departing from the spirit and scope of the invention. The embodiments described herein are meant to be illustrative only and should not be taken as limiting the invention, which can be expressly set forth in the following claims.
