This short video should give you an idea how to use the P-Carriage that comes with all Silver Reed ribbers. The manuals always describe using the device for double bed Drive Lace and pile knitting. I have to tell you that I cannot remember the last time I did either of those techniques – probably when I worked for Studio and was responsible for training dealers!
Drive Lace is a detailed drop stitch lace method worked by using the needle selection (punch cards or electronic) on the main bed to select needles for the drop stitch pattern, while the main knitting is secure on the ribber bed. The P-Carriage is used to drop the MB stitches every two rows, after the needles have been selected and knitted. So, although you are working with 2 beds, the technique produces a single bed fabric – not ribbed.
Pile Knitting also produces a single bed fabric knitted on the ribber bed. In this case, the ribber bed knits both a ground yarn and a pile yarn every row, while the main bed knits only the pile yarn on needles selected by the punch card or the electronics. The P-Carriage releases the loops every two rows.
If either of these methods sounds appealing, I have to refer you back to your manuals because it has been far too long and I use the P-Carriage for something else altogether.
Let me begin by saying that the “hardest” thing any carriage has to do is to push needles from working position (WP) forward in their slots so that the old stitches slide back behind the latches and new yarn is deposited in the hook of each needle. After that, it is fairly “easy” for the carriage to guide the needles back in their slots so that the old stitches slide over the closed latches and form new stitches. The trailing end of the carriage just shoots the needles out, lined up back in WP.
With very tight stitches, non-stretchy yarn, crossed or twisted (or otherwise-manipulated) stitches, it can be difficult for the carriage to push all the needles forward so that they knit cleanly and easily. This is where I rely on the P-Carriage to help.
The P-Carriage is hardly a carriage! There are no knobs or levers to manage and the pathway underneath is a fixed pathway – there are no movable cams – that moves needles between WP and upper-working position (UWP).
When the P-Carriage moves from right to left, all needles in WP are channeled into the pathway where they are pushed forward in their slots so that their stitches slide over and open the latches. They exit the pathway aligned in UWP. The “hard” part has been done.
When the P-Carriage is moved back from left to right, it drops the stitches – which is what you do with Drive Lace or Pile Knitting. – as the needles are returned to WP.
I started using the P-Carriage years ago to facilitate many of the hand-manipulations that I do. I simply slide it across the bed from right to left and then knit 1 row with the main carriage. It adds another step to the knitting, but I really find it is worthwhile.
When working twisted stitches or cables, etc. I may only need to use the P-Carriage every so many rows, but for sticky yarns that won’t knit cleanly, I may use it prior to every pass of the carriage.
There is a similar device, a D-slider, available for some Brother machines, but I am not familiar with the unit and cannot tell you which machines it fits. You’ll have to do a little research. The Silver Reed P-Carriages do not fit other machines because the width (front to back) of the beds differs and it is important for the unit to sit securely on the back rail and slide smoothly across the front edge of the bed.
That said, this blog offers directions for converting the Silver Reed P-Carriage for use on the Brother. The unit itself is inexpensive enough that it might be worth experimenting with!
