The height that the mutual minimum spacing of described panelling element is called in person near the control that equals pusher jack at least.The control heel of pusher jack of the ragged edge of pin chamber is not entered into inside the control track with having additional friction.
Reacting on elasticity in the mutual minimum spacing of panelling element described in the preferred expansion structure loads and can strengthen above minimum spacing.This structure can make the expansion of control track surpass the height of the control heel of pusher jack, if stopped up foreign matter in the control track, they hinder the motion of pusher jack.This means, not damage the control of pusher jack by the control track and call in person that their hinder from the comb crack produces next motion.
Two panelling elements are bearing on the pusher jack of pusher jack panelling movingly perpendicular to the direction of motion of loom slide carriage in favourable expansion structure, wherein preferably make a panelling element in two panelling elements be can control and another panelling element be spring-loading.Parallel the moving of panelling element of the control track of the control heel by making at least two restriction pusher jacks can make pusher jack carry out desired rotatablely moving.
At this advantageously, at least one controllable panelling element makes at least one spring-loading panelling element by interval body motion together in control procedure.The elasticity of the panelling element by non-ACTIVE CONTROL loads and makes this panelling element automatically follow controllable panelling element on a direction of motion.This panelling element is guided with the motion of controllable panelling element by interval body in the opposite direction, and interval body not only can be arranged on the controlled panelling element but also can be arranged on the uncontrolled panelling element.
The described spring-loading panelling element of motion that replaces being parallel to panelling in corresponding expansion structure also can be carried out and rotatablely move, if it follows the control heel motion of the motion of controlled panelling element or the pusher jack by hindering its motion by interval body.
Although can realize also that for the elasticity with the coefficient panelling element of at least one controllable panelling element loads elasticity loads the terminal location of determining of panelling element, can limit the motion of at least one spring-loading panelling element aptly by backstop.These backstops for example can form on panelling by a bearing pin, and a stop surface of spring-loading panelling element leans on bearing pin.
For the controlled motion that discharges panelling element it is contemplated that different structures.In preferred expansion structure, can make at least one controllable panelling element by a control strip motion that is parallel to the direction of motion mobile-bearing of loom slide carriage.This control for panelling element is simple and solid solution on the structure.
Described control strip can have at least one control curve, embeds a guide way that is arranged at least one controllable panelling element therein.Therefore also change the position that to control panelling element and the position that changes the control track that is used for pusher jack thus by moving of control strip.
Described control strip can be arranged on panelling one side that deviates from panelling element, has enough installing spaces can drive by simple mode for use and it there.
Preferably have two be provided with, controllable panelling elements in front and back on the direction of motion of loom slide carriage, they respectively with spring-loading panelling element acting in conjunction, the Trianguli vertical centre axis on the loom slide carriage of being arranged on of one of them controllable panelling element and pusher jack panelling bottom is compared and is provided with in advance on the direction of motion of loom slide carriage and another controllable panelling element ground that lags behind is provided with.In this expansion structure of pusher jack panelling, can control controllable panelling element like this, make by means of leading Trianguli controllable panelling element make pusher jack deflect into the inside, comb crack and by means of lag behind, spring-loading panelling element comes out or makes pusher jack remain on it by two spring-loading panelling elements to produce the position come from the comb crack from comb crack transfer.This is the motion that mainly needs for the fixation guide pin sheet.The fixation guide pin sheet is deflected into comb the inside, crack and during pin produces, fix the mesh of formation in advance there.As long as pin begins its return movement, pusher jack just comes out from comb crack transfer again, is used to make the comb crack to be used for the motion that other participates in the loom parts of knitting process.
