ML1889-26I. GENERAL INFORMATIONA. INTRODUCTIONThe air Operated Underbed Trimmer contains a trimming system that cuts both theneedle and bobbin threads simultaneously. A movable and a stationary blade, mountedon the throat plate are used in combination to pick up and cut the threads.Solid state electronics are used to sense the position of the needle and to trigger thetrimming mechanism at the proper time as well as to control footlifting and backtackingoperations.B. APPLICATIONThe underbed Trimmer/Positioner enables the operator to automatically control theposition of the needle in or out of the work, thereby eliminating the need for hand positioning.In addition, the top and bottom threads are automatically cut beneath the throatplate after positioning. This eliminates the need for hand trimming.C. TRIMMER COMPONENTSThe trimmer components, which can be either pre-installed on the sewing machine headand factory tested, or field installed, include:1. Standard Componentsa. Thread Cutter Assemblyb. Tension Release Assemblyc. Needle Thread Pulloff Assemblyd. Needle Thread Blower and Needle Cooler Assemblye. Foot Lifterf. Folder Openerg.

vendors are getting more bang for their buck by allowing their affiliates to leverage the work that hasalready been done creating product videos. Since it's such a win-win, it's EASY to get permission to use avendor's video, which means you'll have a huge pool of products and videos to choose from. Want Proof?Case Study #1 Eric discovered this strategy back in March of 2006, when he become an affiliate of aprogram called Secret Article Converter. He found that the demonstration video on the sales page was apowerful piece of evidence, and he knew that if people watched it they'd be sold on it. The problem wasthat the video was just one little link on the sales page, and visitors had to go through a squeeze pagejust to get to the sales page. So Eric set up his own page simply with the video and his affiliate link.Instead of sending referrals directly to his affiliate link (in which case they might not even see the salespage, let alone the video), he sent them to his video page to make it 100 certain that they would see thevideo (and keep in mind that Eric did NOT make the video himself... it was already made by the vendor).He became one of their top affiliates, and has received a commission check from Secret Article Converterevery month since then. Commissions: $7,429.75 and counting Case Study #2 When Eric promoted aprogram called CB Niche Builder, he once again found that the demonstration video was an excellentsales tool. Eric made a page containing the product vendor's video (no work for Eric!), and sent viewers ofthe video to his affiliate link. This strategy helped propel him to a nice commission of over $2000.00.Commissions: $2,347.00 Case Study #3 Michael has a lot of good case studies; here is a cool study inwhich Michael used a vendor's video to promote Competition Dominator... It all started with a short emailhe received from one of his list members who wrote: " Help Michael! The Link for the CompetitionDominator video does not play." What was happening is something common that happens whenvendors show a video on their webpage; the video gets over-loaded when too many site visitors are tryingto play it. Come to think of it, if more affiliates would show videos on their own sites it would probablyeliminate most of the "launch day server crashes" we've seen in the past year. Michael knew peoplereally wanted to see this video but they couldn't and he was losing commissions fast unless he didsomething for them. So, as an affiliate for the product he contacted the vendor, and got permission to usethe video. In fact, he used the first version of Affiliate Video Brander (the test model) to see if it wouldsave the day and he was able to download the video and brand it with his own affiliate link, and that wasthe big test to see if the link would work and sales would convert by showing a video at his site. It paid off,and it continues to be a killer strategy every time he uses use it. Commissions: $4,890.87 We have many

ML1889-28The needle is raised to the up position and the trim valve is deenergized.(See INS-1933-4). The flow control in the pilot valve actuator circuit leaks the air slowlyfrom the actuator keeping the valve shifted. Air is applied to the IN port through the NCport, now open, to the thread pulloff cylinder, tension release cylinder and throat plateblower tube.The pilot valve returns (INS-1939-5). Air is applied to the trim cylinder to return theblade. The rate or speed of return is controlled by the flow control which controls the airexhausting from the trim cylinder. This control is used to minimize bobbin spin.C. FOOTLIFT, FOLDER OPENER and THREAD BLOWERWhile the treadle brake is still applied the foot lift solenoid valve will energize(see INS-1939-5). Air is applied to the foot lift cylinder and the folder opener. The foldercan be operated independent of the footlifter at any time in the cycle with a knee operated air valve.At the same time air is applied to the double pilot valve actuators. One actuator has alarger piston than the other. The larger piston will have more force than the smaller oneat the same pressure. The air flow to the larger piston is restricted by the flow to thelarger piston is restricted by the flow control When air is first applied the smaller pistonwill shift the valve and open the port to the shuttle valve. Air will flow to the needlethread blower. Pressure is slowly increasing in the larger piston until it overcomes theother and shuts off the air supply to the blower.IV. ADJUSTMENTSA. TRIMMER1. Cutter AssemblyIn the cut position the cutting edge of the movable blade should pass the cuttingedge of the stationary blade about 1/16". If adjustment is required loosen the locknuts on the cylinder shaft and adjust as required.The pickup position on the movable blade is controlled by the stroke length of thecylinder and proper positioning of the cutting edge as above.2. Thread Pulloff and Tension ReleaseNo adjustment is required for the Thread Pulloff and Tension Release assemblies fortrimmer operations. If check spring adjustment is required for stitch formation,remove the assembly from the machine, loosen the stud lockscrew, adjust springtension, tighten lockscrew and replace assembly.- 3 -

ML1889-29B. THREAD PULLOFF CYCLE TIMEThe flow control in this circuit determines the time these cylinders have to completetheir stroke. Too much time will show a noticeable hesitation before return of the pulloffcylinder. If the time is short the cylinder will not complete its stroke. Turning is (cw) willincrease time, turning out (ccw) will decrease time.C. TRIM CYLINDER SPEEDTurning the flow control needle in (cw) will slow down the cylinder and reduce spin.Turning out (ccw) will increase cylinder speed. If cylinder speed is too slow the presserfoot will rise before the thread is cut and the operator could start removing the garmenttoo soon. If this happens the cylinder speed should be increased and some mechanicaldevice such as star springs used in conjunction with the flow control to reduce spin.D. NEEDLE THREAD BLOWER BLAST TIMEThe duration of this blast is controlled by the flow control mounted to the larger actuator.Turning in (cw) increases time turning out (ccw) decreases time. About one second isenough to give the operator time to remove the garment and blow the thread above thefoot. Should the operator be delayed in removing the garment the thread will remainunder the foot. If the foot is lowered and again raised the above sequence will repeat.- 4 -

AS SOON AS AIR PRESSURE REBUILDS INSIDE THE BOWL, OIL WILL DRIP THROUGHTHE SIGHT GAUGE. CONTROL THE RATE OF OIL ENTERING THE AIR STREAM BYTURNING THE ADJUSTMENT SCREW DOWN TO GIVE LESS OIL AND UP TO GIVE MOREOIL. THIS IS A UNIQUE LUBRICATOR. YOU ADJUST THIS TYPE SO THAT WHILETHE SMALLEST AMOUNT OF AIR IS FLOWING THROUGH IT YOU GET THE DESIREDAMOUNT OF OIL FOR THAT FLOW. THE MORE THE AIR FLOW INCREASES, THE MOREOIL YOU WILL NEED AND THE MORE YOU WILL GET AUTOMATICALLY.HOW TO MAINTAIN:1. PERIODICALLY CLEAN ADJUSTING SCREW NEEDLE VALVE AND SEAT BY SWISHING ACLEANER AND BLOWING OFF WITH AIR.2.
