Abstract: A downward pressing mesh mechanism and sinker thereof for flat knitting machines in which the downward pressing mesh mechanism includes a needle seat containing a bearing surface to hold a plurality of sinkers and knitting needles separated by spacers and a cam holder located above the sinkers to hold a cam. The cam has a guide track to drive the sinkers swinging. The spacers are vertically run through by a bracing shaft at a lower side. Each sinker includes a yarn pressing portion to press a yarn to form a mesh, a swing guide portion driven by the guide track and a shaft rotating recess to couple with the bracing shaft. The sinker thus structured is simpler and durable, hence can be produced and assembled, or repaired and replaced easier and faster. Thus manpower and material costs can be reduced, and product prices also are decreased to meet market requirements.

Abstract: A needle bed structure for flat knitting machines that is located at two sides of a needle bed gap includes a plurality of parallel needle plates, a plurality of knitting needles and sinkers located between the needle plates, a sinker control portion movable in parallel with the arranged direction of the sinkers, and at least one control cam driven by a switching portion to push the sinkers to rotate towards the needle bed gap during the switching movement. The switching portion performs a switching movement according to the moving direction. The needle plates hole at least one needle pressing board to restrict vertical movement of the knitting needles. The switching portion has a magnetic attracting portion corresponding to the needle pressing board to form magnetic attraction therewith. A spacer is provided between the needle plates to prevent the horizontal movement of the sinkers.

Abstract: A yarn feeder for flat knitting machines is located on a yarn feeder guide track to move transversely thereon and includes a baseboard slidably coupled on the yarn feeder guide track, a first rocking arm, a second rocking arm and a yarn feeding unit located on the baseboard. The first and second rocking arms have respectively a first pivot end and a second pivot end coupled with the baseboard, and a first pressed end and a second pressed end to receive a horizontal force to swing respectively about the first and second pivot ends serving as fulcrums. The yarn feeding unit includes a yarn feeding arm located between the first and second rocking arms, and a first linkage bar hinged on the yarn feeding arm and first rocking arm to move simultaneously, and a second linkage bar hinged on the yarn feeding arm and second rocking arm to move simultaneously.

Abstract: A sinker control apparatus for flat knitting machines located on a transverse board over a plurality of knitting needles to drive parallel sinkers hinged between the knitting needles to rotate. The sinker control apparatus includes a base, a linked movement portion located on the base to perform driving movements, a first control cam and a second control cam hinged on the linked movement portion, and a switching portion coupled with the linked movement portion. The switching portion includes at least one connection rod connecting to the linked movement portion, a switching seat coupled on the connection rod and an elastic element coupled around the connection rod to provide a butting force to the switching seat towards the transverse board. The switching seat has a magnetic attracting portion at one side facing the transverse board to attract the transverse board magnetically.
