New Sampling Loom Includes CAD-CAM

<i>New Technology: A new company with a new product boosts turnaround time on woven fabric samples.</i><b>By McAllister Isaacs III, Editorial Director</b>

CAD IIIBy McAllister Isaacs III, Editorial Director New Sampling Loom Includes CAD-CAMNew Technology: A new company with a new product boosts turnaround time on woven fabrics. Youre the plant manager of a weaving plant that produces upholstery fabrics on 120 weaving machines equipped with electronic dobbies. Business is goodyour plant is running full bore, seven days per week, 24 hours per day. If only you didnt have to keep up with so many styles. Its not true that you have 120 styles weaving on your 120 machines. It only seems that way.Truthfully, counting different color combinations, there are 48 different styles in your weaving department at this very moment. Before the week is over, youll make style changes on 24 looms. And you project that many changes every week for at least the next eight weeks.But you arent complaining. Business is good. The weaving machines are running well. Youve topped standard efficiency for the last three weeks, despite the number of changes. Seconds are at an all-time low.Its 10 oclock in the morning. Your meeting with the plants safety committee has just ended. The plant appears to be headed for a new record in number of hours without a lost-time accident.All is well.Youre leaning back in your chair, thinking about the barbecue the company is sponsoring next Saturday for your planta reward for the previous quarters performance.Suddenly the ringing of your phone brings you back to reality. Its the boss. The president of the company says the purchasing director from the worlds largest furniture manufacturers is going to pay a visit.He, the president, will bring him to the plant. Seems the PD wants to see a sample piece of fabric from the new design he sent in yesterday. "Fine," you say. "When are you coming""Today," says the president. "Well see you at 2 p.m. And have that sample ready when we get there."There was a time when, even at the risk of losing your job, you might have responded: "Are you nuts!"But thanks to a new company with a new product, such a task is a piece of cake.

CDC Ltd. (U.S. rep: Peden Textile Equipment Co.) is a new company in Taipei, Taiwan, R.O.C. Its new product is the SL7900, an automatic sampling loom incorporating a CAD-CAM system.Unlike many hand sampling looms, the SL7900 is powered. The fabric woven closely approximates that produced on standard production machines. The SL7900 employs the latest in computer controls and technology as well as pneumatics to drive the system. Sedit is draft design software, which runs under Windows, making the system more reliable and user friendly. It can be installed directly into the SL7900 system, and can even access other dobby CAD systems by network or floppy disk. The system has a simple panel and an instant display, which enables more efficient work.Modifications can be made easily at any time and woven instantly on the loom, allowing the customer to evaluate the changes to the design on the spot. The SL7900 can weave long repeats and provide the same quality as production fabric.The SL7900 can weave a range of fabric types and has the ability to use multiple shafts, multiple weft colors, variable weft density and a wide range of yarn types to suit all weaving applications.The SL7900 is driven entirely by pneumatics, and the modular mechanical parts of the machine allow for ease of maintenance and simplicity. The machine uses the latest industry standard PC, which ensures precise control of all the functions, including single rapier weft insertion, multi weft selection, automatic weft cutting, shedding, weft beat-up fabric takeoff, etc.A special feature on the SL7900 is a separate stand to store pre-drawn heddle frames, which reduces changeover time, maximizing sampling time. Optional features include:o Quick-change heddle framequick and easy to change up to 20-piece, pre-drawn heddle frames.o Positive warp tensioningprovides first-class weaving quality.Here Are The SL7900 DetailsNominal weaving width1-10 in.SpeedUp to 30 ppm, depending on yarn typePicks sequence1-6 weft yarns in any sequenceFabric take-offComputer-controlled weft densitySheddingControl of 1st to 20th shafts by computer-controlled air cylinderShaftIndividual shafts and reed for independent drawing-inWeft insertionAutomatic rapier with special 1-lancerapier designWeft stopAutomatic sensor controlDesignIntegral Sedit softwareMotion1.6-hp compressor controlling all pneumatic functionsPower110v/220v, 50-60 HzMicroprocessor controllerPC-based controller operating under WindowsOctober 2001
