Description

The flat machine that has sinker holding

Technical field

The present invention relates to a kind of flat machine (Flachstrickmaschine), but the pin that it has opposed needle-bar and be arranged to vertical shift in needle-bar, wherein, each pin is associated with a sinker holding (Niederhalteplatine), and this sinker holding is arranged to and can adjusts between closed position and open position.

Background technology

The known for a long time sinker holding that in flat machine, uses.For example file DE 39 35 763A1 have described a kind of flat machine that has sinker holding, these sinker holdings work on lopping device (Maschenbilder) next door of rigid arrangement, and these sinker holdings swing in its closed position and the open position by means of the control cam.The gripping surface of this sinker is crooked (abgewinkelt), thereby obtains the hook-type profile on the top (Spitze) of sinker holding.Gripping surface arrives relatively far under the plane of the bottom side qualification of passing through pin in the closed position.By this uniqueness

Though the hook-shaped configurations of closed position and sinker holding can make sinker holding satisfy it highlightedly and grip function, applies relatively large power to the coil (Masche) for the treatment of pulling (zur ü ckhalten) at this sinker holding.At this, the stress that produces in coil by this power may be so big so that when making pin (coil remains in the pin) when advancing forward, coil is broken, because the pin cross section of latch needles becomes greatly constantly, after coil is positioned at the needle latch of opening.Knitting that has the coil that breaks is waste product, therefore must avoid coil to break as far as possible.

File EP 1 347 088 B1 have described the another kind of design of sinker holding, and this sinker holding has the top that is configured to hook-type equally, and because the darker closed position of sinker holding applies similar bigger power to coil.Also can cause coil to break at this.

In addition, two known sinker holdings are located to swing to only in the open position of relative restriction owing to its coil that is bearing in needle-bar closely forms zone (Maschenbildungsbereich).In open position, the gripping surface of sinker also is positioned at the hook inner space of the pin under it.Therefore, especially may cause the top of sinker holding to penetrate into part in the hook-shaped configurations on the top of sinker holding under individual cases knits in the line (Strickfaden), knit the hook that line is arranged in the knitting needle of implementing to retract motion, and should utilize this to knit line to form new coil.The line of knitting of being controlled by sinker holding in the swivel motion that pulls at pin is partly broken.This can see and cause knitting to be worth reduction on the surface of fabric.

Summary of the invention

The objective of the invention is, a kind of flat machine is provided, this flat machine sinker holding allows finished yarn, and can not cause coil to break.

This purpose is achieved by the flat machine that starts mentioned type, be characterised in that according to this flat machine of the present invention, sinker holding has flat gripping surface, under the bottom side of the pin under this gripping surface is positioned in the closed position of sinker holding, wherein, gripping surface and the plane that the bottom side limited by pin are at the angle of maximum 10 ° of double team each other.

Sinker holding according to flat machine of the present invention sinks under the pin bottom side in its closed position always, and therefore plays equally and hold the effect that remains on the coil in the pin reliably.But because gripping surface is designed to the flat hook-type and the angle of acting surface and maximum 10 ° of the plane double team that limits by the pin bottom side in addition of not bending to, therefore the force rate that is applied on the coil when gripping is obviously little in known sinker holding.Therefore, when making knitting, can obviously reduce the danger that coil breaks by (empfindlich) thin and/or rapid wear yarn.In addition, knit line by gripping surface being designed to flat (promptly by saving the hook-shape structure on sinker holding top) than obviously more impossible in the open position of sinker holding, the damage in known sinker holding.

If should get rid of in open position the line loss of knitting that the top owing to sinker holding causes fully hinders, then can make gripping surface in the open position of sinker, be arranged in such plane, that is, this plane is tangential to the hook inner space of affiliated pin or extends on the hook inner space.In the design according to flat machine of the present invention, when sinker holding was arranged in its open position, the line of knitting that is arranged in pinhock did not contact sinker holding.Therefore, can be noiseless and realize under the undamaged situation of line that coil forms knitting.

Other advantage is that sinker holding can be adjusted between its closed position and its open position by swing.So, sinker holding must only support and additionally can not be shifted to be used to carry out translational motion swingably.

Aptly, also can make according to the sinker of flat machine of the present invention and adjust by means of the control cam at the slide plate place that is arranged in flat machine.The motion of this control cost favourable and feasible motion that makes sinker holding in simple mode on the structure and pin is complementary and becomes possibility, and pin is equally by the control cam loading at the slide plate place that is arranged in flat machine.

In the preferred design of flat machine, the gripping surface of sinker holding carries out the transition in the end face of sinker holding under the situation on the top that is configured with rounding, wherein, the top has in the closed position of sinker holding with respect to the central plane between opposed needle-bar, the spacing of 0.1mm at least.The rounding on sinker holding top and the minimum spacing of keeping with respect to the central plane of flat machine provide, and can not cause the opposed sinker holding collision of two needle-bars.

At this, also advantageously, the end face of sinker holding is extending by the mode under the plane that the bottom side was limited of this pin with the bottom side of the pin that is parallel to opposed needle-bar and with the spacing of 0.2mm at least in the closed position of sinker holding.In this design, guarantee, make sinker holding in its closed position, not hinder the motion of the pin of opposed needle-bar equally.

In addition, can be equipped with the lopping device according to flat machine of the present invention, this lopping device is arranged in the needle-bar place rigidly and the lopping device makes the formation of uniform coil become possibility.For the knocking over (Abschlagen) that is easy to coil can be in known manner by all lopping device guiding knocking over lines (Abschlagsdraht).
