Abstract

PURPOSE: To simplify production, construction and fitting of needle beds by arranging a board at a correct gauge in the whole length of the needle beds, making gaps between main plates at an upper part of a bottom board be the same breadth and making knitting needle to be pierced through the gap have the same play in everywhere. CONSTITUTION: This needle bed constructs a needle bed segment 11 with a higher main board 12 and a lower bottom board main board 13 and pierced streak plates 19 are inserted into pins 18. The pierced streak plates have squarely formed holes at a correct distance X coincident to the gauge and pins 18 in the main board 12 is fitted to the holes. Pins at a lower face of the main board 12 are fitted to rectangular groove holes of pierced band 21 having same length with the needle bed to ensure a correct gauge of the board in the whole length of the needle bed.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to needles for flat knitting machines and circular knitting machines, which are composed of a large number of needle bed segments composed of a raised main plate and a lowered bottom plate between them. Regarding the floor.

<Prior Art> Various embodiments of this type of needle bed are known. Such needle beds are problematic, especially when the gauge of the plates grouped into segments is not maintained across the width of the needle bed segments, and furthermore, when the needle bed segments are grouped together to form a complete needle bed. Gauge problems also occur because the gauge of the adjacent plate cannot be accurately maintained at the butt surface. This is due, inter alia, to the fact that the plate or the needle bed segment is compressed by various pressure means, and also because the plate is not exactly flat (or the plate surfaces are not parallel planes).

<Problems to be Solved by the Invention> The present invention has the plates disposed at an accurate gauge over the entire length of the needle bed, and the gaps between the main plates above the bottom plate all having the same width.
The object is to construct or improve needle beds for flat knitting machines and circular knitting machines of the relevant type so that the knitting needles passing through this gap have the same play everywhere for freedom of movement.

Furthermore, the aim is to simplify the manufacture, assembly and installation of the needle bed so that the certain expenditures previously required are no longer necessary. Finally, if a needle bed segment ever needs to be repaired or replaced, insert the new segment in place of the segment you removed from the needle bed without causing a change in gauge ratio (insert it exactly to the original exact gauge). We must achieve the objective of continuing to maintain the

Means for Solving the Problems> In order to achieve the above object, the present invention proposes to configure the needle bed as specified in the characterizing part of claim 1. Further advantageous formulations of the subject matter of the invention emerge from the dependent claims and the following description of the preferred embodiment shown in FIGS. 1 to 5 of the drawings.

Claim 1 and dependent claims are as follows.

(1) In needle beds for flat knitting machines and circular knitting machines, which are composed of a large number of needle bed segments consisting of a high main plate and a low bottom plate between them, l A plurality of pins are disposed in a straight line, into which a piercing bar with a pin hole is inserted, the length of which bar is approximately equal to the width of the needle bed segment, and the length of the bar is approximately equal to the width of the needle bed segment. A needle bed characterized in that an end of the pin protruding from a pin hole of a perforation bar on the lower surface is inserted into a hole of a perforation bar extending over the entire length of the needle bed.

(2) The needle bed according to claim 1, wherein the pins are arranged in notches in the upper and lower surfaces of the main plate.

(3) By tightening each of the main plate and the bottom plate using an engagement pin hole provided in the bottom plate and an engagement pin provided in the main plate and engaged with the engagement pin hole, The needle bed according to claim 1 or 2, wherein the needle beds are connected to each other.

(4) The needle bed according to claim 3, wherein the engagement pins of the main plate are laterally embossed by removing material of the main plate.

(5) The needle bed according to claim 3 or 4, wherein the front engagement pin hole of the bottom plate is formed in a circular shape, and the rear engagement pin hole is a slotted hole.

(6) The needle bed according to any one of claims 1 to 5, wherein both sides of the main plate and the bottom plate are flattened in a corrugated or honeycomb shape.

<Embodiment> As can be seen from FIG.
It is composed of 3.

Advantageously, one main plate 12 and one bottom plate 13 are connected together, for example by inserting pins 14 into holes in the main plate 12.
Instead of this pin 14, it is also possible to retain the pin 14 of the main plate 12 by embossing, by extruding material laterally from the main plate to form the pin 14.

Among the holes 15 or 16 provided in the bottom plate 13, the hole 15 near the front end is formed in a circular shape, and the remaining holes 16 are rectangular slots. Hole 15 or 16 is of such a diameter or bore that it receives pin 14 from the inside in a press fit.

There is a notch 17 on the bottom surface of the main plate 12, and a pin 1 is located in the center of the notch 17.
8 are arranged. The same number of notches 17° are also present on the upper surface of the main plate 12, also having pins 18'. Into these pins 18 or 18°, piercing bars 19 shown in FIG. 4 are inserted to form needle bed segments 11.

The drilling bar has a square shaped hole 20 at a precise distance X to match the gauge, into which the pin 18 of the main segment 12 engages.

As can be seen from the drawing, there are three perforation bars 19 on the top side of each needle bed segment 11, and four perforation bars 19 on the bottom side.
9 is inserted into pin 18.

To join the needle bed segments together to form an intermittent needle bed unit, a perforated strap 21, shown in FIG. 5, is used whose length corresponds to the length of the needle bed.

This perforated strap 21 has rectangular slots 22 into which pins on the underside of adjacent main plates 12 respectively engage, thereby ensuring accurate gauge of the plates over the entire length of the needle bed. Ru.

In order that the needle bed segment or its plate is in close contact with the upper surface of the needle bed base and is clamped against said upper surface by means of a mounting and tightening element that engages in the dovetail groove 23, a cutout 17 is provided on the lower surface of the main plate 12. A pin 18 for inserting the perforation bar 19 or the perforation band 21 is arranged in the notch.
It's on the underside of the . In order to prevent the perforation bar 19 from protruding upward from the upper edge of the main plate 12, an appropriate notch 17' is also provided on the upper surface of the main plate 12.

Although the embodiments described above relate to needle beds for flat knitting machines, the present invention can be similarly applied to the manufacture of needle beds for circular knitting machines. In that case, the perforation strip 19 fixed to the upper surface of the main plate 12 is replaced by the perforation strip 19 disposed on the lower surface of the main plate 12.
Of course, this means the gauge of hole 20.

In order to obtain a needle bed segment 11 in which the main plate 12 and the bottom plate 13 are constructed exactly flat and are essentially easy to assemble, the plates are flattened on both sides in a corrugated or honeycomb-like manner, so that the parallelism of the two surfaces Planarity is achieved and latent stresses present in the material are removed.

<Effects of the Invention> According to the present invention, manufacturing, assembly, and attachment of the needle bed are simplified. At this time, the gauge ratio is extremely accurate.
