摘要:
A tubular knitted stent or stent graft for placement in a lumen or body passage is compressible, thus presenting a compressed outer diameter and a non-compressed outer diameter. The stent or stent graft has knitted loops each having a loop width, wherein the loop width to non-compressed outer diameter ratio is larger than 0.2 for at least one knitted loop.

An apparel system includes a lily yarn machine for knitting lily yarns, and a flat knitting machine having at least two needle beds for knitting according to knitting data. A controller is connected to the lily yarn machine and the flat knitting machine for controlling the lily yarn machine to produce a lily yarn in a quantity which is required by the flat knitting machine according to the knitting data for the flat knitting machine.
摘要:
A circular knitting machine, in particular for knitting hosiery, is disclosed, wherein the dial is rotated by the needle cylinder through a rod extending coaxially with the cylinder and dial and rotatively connected to the latter. The rod can be shifted axially from a position of engagement with a drive element rigid with the cylinder, to a position of disengagement therefrom, and viceversa. In the former condition, the dial will be rotated in timed relationship with the cylinder, whereby the fabric is knitted normally, whereas in the latter condition, the knitted fabric is discharged. The rod axial movement may be obtained by pneumatically or hydraulically operated cylinder, whose piston is rotatably connected to the rod itself. It is further possible to make the dial raisable vertically through a pneumatic or hydraulic cylinder, such as to make the loop formation area fully accessible.

A flat bed or circular knitting machine has an additional bed which accommodates in grooves or tricks pairs of yarn-guide members which are controlled alternatively by cams to co-operate with needles of the machine. The ends of each yarn-guide member carries a hook which co-operates with an eyelet to effect the actual guiding function.
摘要:
A circular knitting machine of the type providing a reinforcement of knit tubular fabric for flexible hose including a plurality of circumferentially spaced, vertically reciprocating needles. A yarn guide holder is rotatable with the machine relative to the knitting needles and carries vertical supports for connection of a hold down ring. The hold down ring affixes to the yarn guide holder and is vertically adjustable relative to the yarn guide holder for gap adjustment purposes. The hold down ring is rotated by the machine simultaneously with the rotation of the yarn guide holder in a manner to assure even wear caused by repeated contacts by the knitting needles.
