摘要： Apparatus for detecting broken hooks of needles in a knitting machine having first and second cam faces defining a cam for slidably receiving needle butts. The cam includes a raising cam portion, a stitch cam portion, and a gate cam portion in which tension forces between yarn loops and hooks bias the butts of intact needles against the first cam face. The detector has a detector butt raising segment wherein the second cam face in the gate cam portion is inclined away from the second cam face at the stitch position for urging butts toward the first cam face. A detector butt lowering segment follows the detector butt raising segment, in which the first cam face urges the butts toward the second cam face. A recess segment follows the butt lowering segment. The recess is formed so that the second cam face is sufficiently spaced from the first cam face so that butts of needles having broken hooks are urged into the recess segment by the detector butt lowering segment but butts of intact needles that are biased against the first cam face do not enter the detector recess segment. A sensor identifies butts of broken needles in the detector recess segment. The apparatus may further include means for stopping operation of the knitting machine when the sensor is activated. A method for detecting broken hooks is also provided.

摘要： The knitting machine is provided with latch detector means for detecting a latch improperly positioned in a closed position and for signaling when such a condition occurs. A trigger lever (30) having a free inner end (31) is normally positioned in an operative latch detecting position (FIG. 3) immediately below the path of travel of the hooked upper ends (10) of the needles N so that a latch (11) in the proper open position will not engage and trip the trigger lever (30) while a latch (11) in an improper closed position will engage and trip the trigger lever (30). A tension spring (45) is provided to immediately move the trigger lever (30) to the inoperative position (FIG. 4) with the inner free end (31) outwardly and away from the path of travel of the needles N upon being engaged by a latch in an improper closed position.

摘要： A method and apparatus for detecting defective knitting needles in a circular knitting machine wherein the knitting needles are advanced along a circular path between a light source and upper and lower vertically spaced photoelectric detector devices. The direction of the light beams from the source to the two photoelectric devices is inclined at an angle to the tangent of the circular path at the beam intercept with the circular path, such that the advancing needles pass successively through the beams and a shadow of the hook end of each needle is cast on the upper photoelectric device before any shadow of any other part of the needle is cast on the lower photoelectric device, when a nondefective intact needle enters the beams. Needles with broken off hooks or closed needle latches cause a shadow to be cast on the lower photoelectric device before any shadow reaches the upper photoelectric device to activate an alarm and/or stop the knitting machine. A third photoelectric device may be positioned to receive a shadow of a different needle from the one being inspected by the upper and lower photoelectric devices to detect needles broken off too low to cast a shadow on the lower photoelectric device.
摘要翻译： 一种用于检测圆形针织机中的有缺陷织针的方法和装置，其中织针沿着光源和上下垂直间隔的光电检测器件之间的圆形路径前进。 从源极到两个光电器件的光束的方向在与圆形路径截取的光束处以圆形路径的切线成一定角度倾斜，使得前进针连续地通过光束并且 任何其他部分的任何阴影投射到下部光电装置上时，每个针的钩端投射在上部光电装置上，当无损的完整针进入光束时。 断针或闭锁针的针头在任何阴影到达上光电装置之前会在下光电装置上施加阴影，以激活报警和/或停止针织机。 第三光电装置可以被定位成接收不同针头的阴影与被上和下光电装置检查的针的距离，以检测断开得太低而不能在下光电装置上投射阴影的针。

摘要： In a knitting machine having at least two co-operating arrays of independently actuable latch needles arranged in opposed needle beds, a carrier located above the needle beds and movable longitudinally of the needle beds and a hold-down element supported from the carrier for holding down knitted loops as the needles rise, the carrier is mounted so as to be capable of movement between a first level and a second level which is raised in relation to the first level. Movement of the carrier to said second level, caused for example by the hold-down element striking a needle which has failed to descend, is employed to actuate means for producing a warning signal and/or for stopping the knitting machine.
