摘要： A presser foot, for a knitting machine having independently operable needles located in opposed needle beds, has a leading portion and a trailing portion extending rearwardly from the leading portion. The leading portion comprises a member with a smooth surface adapted to contact knitted loops when the presser foot is in use, the forward part of this smooth surface being higher than the rearward part and the two parts having a smooth transition between them. This member is adapted to resist deformation by the forces applied by knitted loops and is so shaped that the inclination of the forward part of said smooth surface which first contacts the knitted loops during relative movement of machine needles and presser foot, in use, is inclined to the direction of said relative movement at an angle less than 35.degree.. The trailing portion of the presser foot, at the location where it departs from the leading portion, is at a level substantially the same as or higher than the level of the rearmost stitch-contacting section of said leading portion. The trailing portion is adapted to be resiliently deflected in an upward direction by the forces applied to it, in use, by knitted loops.

摘要： A presser foot for a knitting machine with independently operable needles has a cross-section which is triangular or approximately triangular.The presser foot may comprise two elements of strip-like form, for example of metallic sheet material, extending side-by-side in the longitudinal direction of the presser foot. These two elements are arranged so that longitudinally extending edges thereof which are intended to press on knitted loops and to be the lower longitudinally extending edges of the elements, in use, are more widely separated than the longitudinally extending edges of the elements located above them and intended to be the higher longitudinally extending edges, in use.

摘要： A flat knitting machine including a presser foot assembly comprising a support mounted on the machine for movement along the needle array of the machine and at least one presser foot mounted on the support. The assembly includes a supporting arm carried on the support and itself carrying a slider on which a presser foot is mounted, the supporting arm providing a structure for effecting guided displacement of the slider up-and-down in relation to the needles. Resilient means, such as one or more springs, are arranged to urge the slider and presser foot down, away from the support, so that the presser foot can ride up on the supporting arm against the pressure of the resilient means and thus the whole of the presser foot extending from in advance of the rising needles to the rear of the fully raised needle position is resiliently mounted in the machine.

摘要： A composite structure such as an aircraft brake disc has a matrix material reinforced by knitted panels of fabric arranged in a stack. The panels are knitted directly into the desired disc shape so that there is no fabric waste, by knitting a helix of fabric on a flat-bed weft knitting machine having a patterning mechanism which allows shaping and a presser foot or sinkers to hold the knitting down on the needles. The helix of fabric can be closed down to constitute the stack of disc panels directly or it can be separated into discrete disc panels by knitting in draw threads connecting successive windings of the helix. The disc panels may be knitted from oxidised acrylic yarn and then heated to carbonise the yarn. A stack of carbon fibre fabric panels may be embedded in a carbon matrix by carbon vapor deposition to form a brake disc.

摘要： A yarn take-up mechanism for a knitting machine, especially a flat V-bed knitting machine comprises a yarn take-up arm pivotally mounted at one end on a stanchion and urged by a spring to pivot so that its other end moves away from the stanchion. Said other end of the arm carries a movable yarn guide and the yarn path in the take-up mechanism is from a fixed yarn guide on the stanchion through the movable yarn guide and back to the other fixed guide on the stanchion, the fixed guides being close together and adjacent the location of the movable guide when it is in the position closest to the stanchion. The end of the take-up arm carrying the movable yarn guide is flexible whereas the remainder of the arm is stiff.
