Knitting Machine Carriage Jammed

Today whilst I was busily working away, with a deadline looming the carriage of my knitting machine jammed. This has happened many times in the past and I know exactly how to deal with the problem or so I thought. Usually all I need do is unscrew and carefully remove the sinker plate and then turn the dial on the carriage to CR (Carriage release) and then lift the carriage off the rails. The problem I encountered today though was that the dial would not turn to CR and therefore I could not lift the jammed carriage. The following is what I did to cure the problem; I sat directly in front of the jammed carriage and looked at the stuck needles HEAD ON. I visually examined them hoping to spot any needles which looked out of place in any way. I found two needles which looked out of place. One was twisted slightly to the left and one was slightly raised above the level of all others. These two needles I carefully 'jiggled' and after a little bit of jiggling they became unjammed and then I was able to turn the dial to CR and release the carriage. I replaced both needles with new ones and I was back 'in business' once again. If this happens to your machine (and my guess it will at some stage) remember always treat your machine with kindness.Don't bang and bash it. Take time to look and then never force anything. Jiggle and jiggle gently!!
