A sinker equipped with lubrication oil channeling and separating structure is an element of a knitting machine which includes at least a dial, a sinker disc, an oil ejection nozzle to sprinkle lubrication oil and a yarn feeder. The dial includes a plurality of needle troughs to hold respectively a knitting needle. The sinker disc includes a plurality of sinker troughs to hold the sinker. The sinker includes a base located in the sinker troughs, a driving nub located above the base, a knitting portion located at a front end of the base, an oil sprinkling zone interposed between the base and the knitting portion, and a lubrication oil channeling and separating structure interposed between the knitting portion and the oil sprinkling zone. The lubrication oil channeling and separating structure includes a separating slot, a flow channeling portion and an oil blocking portion that are around the separating slot.

A flat bed knitting machine having an oil feeding device is disclosed. Lubricant oil is fed, just when needed, to knitting members, such as needles, jacks and sinkers. The numbers of operations of knitting members are counted, and when a counted number exceeds a predetermined value, lubricant oil will be sprayed from a jet-type nozzle to the relevant knitting member.

A lubricating method and apparatus for a circular knitting machine which involves inputting operating conditions for the circular knitting machine from an operating conditions input device 30, after which a pump squirt quantity per squirt is computed by a squirt quantity computing device 33 and set in a squirt quantity setting device 21, a pump squirt velocity is computed by a squirt velocity computing device 34 and set in a squirt velocity setting device 22, and an intermittent pump operating period is computed by an intermittent period computing device 35 and set in an intermittent period setting device 24. Subsequently, a start signal is sent from a start signal sending device 25 after each set intermittent period, and a pump drive device 23 drives the pump 12. As a result, an appropriate quantity of lubricating oil is squirted from a nozzle 13 towards a cam groove 4 of a cam 5 for a duration of at least one revolution of a row of needles 1 of the circular knitting machine. Wastage of lubricating oil can thus be reduced to an insignificant amount, and the lubricating oil can be spread uniformly to all required locations without lubricating oil contamination of the surroundings, thereby preventing nonuniform lubrication and ensuring machine durability.

An apparatus and method for flushing lint and other debris from the cylinder needle and sinker rest ring slots of a circular knitting machine utilizes a pair of nozzles disposed closely adjacent the upper end of the cylinder to inject into the slots from one nozzle a narrow pressurized stream of flushing oil and from the other nozzle a similar stream of pressurized air, either on an alternating or simultaneous basis, periodically over the course of operation of the knitting machine, preferably once every twenty-four hours, i.e. three work shifts, of machine operation.

The invention relates to a carrier (1) of annular, cylindrical, plate or disc form or the like in a circular knitting machine for mounting needles, sinkers, cam parts or the like. The carrier (1) comprises at least one flow channel, which serves for the transport of a gaseous or fluid medium intended for heat exchange and/or lubrication. This flow channel consists of a recess (9) formed in the carrier, adjoining a surface of the same, and a cover (10) covering the recess, sealed to the carrier (1) and comprises at least one connection (11, 12) for the feed and/or removal of the medium (FIG. 1).

In a lubricating device for a plurality of lubricating stations, in particular for supplying lubricant to knitting machines, a pump device is provided that serves at the same time as a distributor device. To that end, the pump device has a piston which is provided with a control groove. The corresponding pump cylinder has an inlet and a plurality of outlets distributed over the cylinder wall. Depending on which of the outlets the control groove of the piston is made to coincide with, a corresponding lubricating station is selected. The pump device is thus a distributor device as well.

A knitting machine is disclosed in which measurements are made reflecting the output characteristics such as the forces incident to the operation of the knitting needles relatively to operating cam means therefor, and a system is provided for influencing one or more of the operating characteristics of the knitting machine such as speed of operation, rate of lubrication, or the like, in response to such measurements.

Spaces and passageways are formed behind the knitting elements in cylinder constructions associated with circular knitting machines and cut-out portions or circumferential grooves are provided in the walls which constrain the movement of the elements and such cut-out portions communicate with the spaces to allow lubricant applied from at least one position outwardly of the knitting elements and at locations juxtaposed to the cut-out portions of the walls to pass between the knitting elements into the spaces which include lubricant reservoirs to (a) facilitate the lubrication of these elements, and (b) to improve heat transfer away from portions of the machine at which frictional heat is produced by the sliding action within their respective slots of sinkers, needles, or other knitting instrumentalities. Also, a provision is made for improved lubrication between the needle and the cylinder by relieving a back portion of the needle to create a lubricant reservoir in the offset portion of the needle. Further, lubricating means positioned outwardly of the knitting elements are provided to apply lubricant to at least two sides of the knitting elements. In addition, a provision is made to lubricate the cylindrical bearing surface of the sleeve gear member on which the cylinder is slidably mounted for relatively vertical movement.
