Definitions

  • the invention relates to a tool set for equipping a bar of a knitting machine and a bar, which is adapted to receive tools, in particular the tool set according to the invention.
  • the bar of a knitting machine holds a large number of tools, such as needles, sliders and the like aligned parallel to each other at predetermined intervals resting on each other. When the bar is moved, all the tools perform the same movement.
  • the tools are mounted at fixed distances from each other on the bar. The distances are usually determined by grooves which are incorporated parallel to each other in the bar and which receive the holding parts of the tools.
  • the measure of the division is the fineness. She is through given the number of tools per English inch. A fineness of E40 denotes 40 knitting tools per inch.
  • the tool set according to the invention contains tools of at least a first type and a second type, which differ in the design of their holding parts.
  • the tool set can be divided into at least two groups of tools, which are arranged alternately on the bar.
  • the holding parts are used to attach the tools to the bar and set the position of the tools.
  • the pitch ie the distance of the juxtaposed tools is determined from each other.
  • the concept of the different design of the alternately arranged holding parts of the two different types of tools allows it to be provided for positioning and pitch fixing means outside the immediate spaces of adjacent holding parts. As a result, the entire bar length can be exploited and filled by the holding parts.
  • the widths of the individual holding parts can be determined by dividing the bar length by the number of holding parts to be stored in total becomes. Between the individual holding parts neither partitions nor other means are required to effect the positioning of the tools. The positioning can be made at those portions of the holding parts with which the holding parts of the first and second types of tools differ from each other.
  • This concept allows the construction of ingots and tool sets that define an extremely fine pitch of significantly greater than E40.
  • the tools are relatively robust, because their width to be measured on the holding parts can be at most equal to the pitch.
  • the Barre does not require any structures whose width would be significantly less than the pitch itself. This also results in a robust bar that can be manufactured efficiently and accurately.
  • the tools of the first and second types have mutually matching stitch forming areas, working parts.
  • the working parts are for example hook, slider, slide slot, knife, eyelets or the like.
  • the working parts of the tools have a width which is smaller than the width of the holding parts.
  • the width is measured along the bar and thus transversely to the longitudinal direction of the tools and is defined by the distance of the side surfaces of the tools.
  • the working parts can be at least as wide as the holding parts.
  • the holding parts of the tools of the at least two different types preferably differ in at least one predetermined axial position in their holding part height.
  • the height of the holding part is measured perpendicular to the bar and at the same time perpendicular to the longitudinal direction of the tools.
  • the holding part height is the distance between the upper and lower narrow sides of each holding part at the given location.
  • the different holding part height at the given axial position of the two different types of tools allows the design of a first embodiment in which e.g. only the tools of the first type are positioned on the bar via suitable positioning means.
  • the positioning means may consist in grooves, slots or other recesses into which grip the holding parts with their greater height.
  • the holding parts of the tools with lower holding part height can then be arranged between these positioned tools and are thereby automatically positioned.
  • the tools of one type to a certain extent form the groove walls to form the grooves for receiving the holding parts of the tools of the other type.
  • the holding parts of the tools of the two different types of the bar each own recesses, which are offset with respect to the longitudinal direction of the tools against each other.
  • the tools of the one type have a greater height at a front holding portion
  • the holding portions of the tools of the second type have a greater height at a rear portion.
  • At the barre are for the holding parts the tools of the first type, a first row of recesses and formed for receiving the holding parts of the tools of the second type, a second series of recesses.
  • the two rows of recesses are then offset, for example, by the pitch in Barrenltician against each other.
  • the recesses may for example be grooves or slots.
  • one row of recesses is located in a front area of the barre and the other row is in a rear area.
  • the two rows are offset from each other in the tool longitudinal direction.
  • the positioning of the tools in a direction perpendicular to the bar longitudinal direction and tool longitudinal direction (vertical direction) is typically effected by the bearing surface of the bar itself, in which the recesses are introduced. But it is also possible to have the example slot-shaped, oriented in the tool longitudinal direction recesses transverse, so to let cut in Barrenlnaturescardi of a positioning, which is deeper than the individual tool grooves.
  • Such a positioning groove can also be arranged in a not provided with recesses or slots area of the bar. It serves to receive positioning projections, which are attached to the tools and serve to determine their height position. In this case, the tools are not resting against the contact surface, ie the upper side of the bar.
  • the axial positioning of the individual tools is preferably taken over by a separate foot, which projects into a groove provided for the barre.
  • This foot is preferably identical to the holding parts of the tools of both types.
  • a barre 1 which belongs to a knitting machine.
  • the bar holds a number of tools 2 arranged side by side along the longitudinal direction B of the bar.
  • the tools 2 each have a longitudinal direction W, which is oriented transversely to the longitudinal direction B.
  • the tools 2 are, for example, knitting tools in the form of knitting needles, sliders, hole needles, knives or the like. They are used to produce knitwear in textile production.
  • the tools 2 constitute a tool set 3 comprising a number of tools 4 of a first type and a number of tools 5 of a second type, as is known FIG. 3 evident.
  • the tools of the first type 4 each have a working part 6 and a holding part 7.
  • the tools 5 of the second type each have a working part 8 and a holding part 9.
  • the working parts 6, 8 preferably coincide with each other. Thus, a uniform font is formed on the bar 1. Assign the working parts 6, 8, for example, at their ends hooks 10, 11, these hooks are on a common line. However, the tools 4, 5 differ in the formation of their holding parts 7, 9. These each have a thickness which is to be measured between their side surfaces transverse to the tool longitudinal direction W. The thickness is only slightly smaller than the center distance of adjacent tools 4, 5. The thicknesses of the two working parts 7, 9 preferably correspond to one another. However, they differ in the present embodiment in their height, which is to be measured in the direction H between the respective narrow sides 12, 13, 14, 15 of the holding parts 7, 9.
  • the tools 4 and their holding parts 7 are assigned to the bar 1 recesses 16 in the form of grooves. These recesses 16 cut through the upper support surface 17 of the bar 1 and are oriented transversely to the longitudinal direction B of the bar 1. Their width is substantially equal to the width of the holding parts 7 of the tools. 4 of the first type. Their depth corresponds to the height difference between the holding parts 7, 9 of the tools 4, 5. The distance between adjacent grooves or recesses 16 from each other corresponds to twice the pitch. The pitch is the center distance of adjacent tools 4, 5. While the holding parts 7 of the tools 4 rest on the bottom of the recess 16, the holding parts 9 of the tools 5 rest on the support surface 17. Their upper narrow sides 13, 15 lie in a common plane and are clamped by a terminal block 18 against the bar 1.
  • the holding parts 7, 9 may differ in their height, they preferably coincide in their length with each other. They preferably each have at the same axial position a foot 19, 20, e.g. protrudes from the lower narrow side 12 and 14 away. It is associated with a longitudinal groove 21 in the bar, which extends parallel to the longitudinal direction B and transverse to the grooves 16. It serves for the axial positioning of the tools 4, 5.
  • the bar 1 is equipped with tools 2 of the tool set 3 by the tools 4 of the first type are inserted into the grooves 16. Their holding parts 7 now form between each other receiving spaces or slots for receiving the holding parts 9 of the tools 5 of the second type.
  • the tools 4 are positioned by the grooves 16 in the longitudinal direction B according to a predetermined pitch and that in the double pitch.
  • the recesses or grooves 16 cross-sections of the holding parts 7 together with the recesses 16 form a positioning means 22 for the tools 4 of the first type.
  • the tools 5 of the second type are assigned no such positioning means. However, they find their position by passing with minimal play between the holding parts 7 of the adjacent tools 4.
  • the tools 4, 5 can support each other. Between you remain a barely noticeable slot or they lie without bias with their flat sides together. In the slot elastic or plastic elements or an elastic or plastic damping material can be provided. It can achieve divisions of E50 and finer.
  • the tools 2 remain robust. They make use of the maximum available thickness, in particular in the area of their holding parts 7, 9.
  • the working parts 6, 8 of all tools 4, 5 may be oriented parallel to each other. Their thickness may be slightly less than that of the holding parts 7, 9.
  • the grooves or recesses 16 need not necessarily have the same width as the working parts 7. Rather, it is also possible to make the grooves or recesses 16 narrower and the corresponding provided for engaging in the recess 16 portion of the holding part 7 also in accordance with to reduce its thickness. It thus becomes a centric or eccentric longitudinal rib, which forms the required positioning means 22 together with the groove. It is also possible to provide instead of the groove 16 a towering from the support surface 17, narrow, eg web-like projection having a substantially smaller width than the holding part 7 of the tool 4. This projection can engage in a longitudinal groove of the holding part 7, the is provided on the lower narrow side 12.
  • the desired positioning means 22 is also provided on the bar 1 projection, which engages in the longitudinal slot of the holding part 7, the desired positioning means 22. It is also possible to form this projection or rib by a thin plate or bar, which in a barre in addition to this trained groove is inserted. Also in this embodiment, in turn, the basic principle is realized, according to which the positioning means only on each second holding part. 7 engages and the intermediate holding parts 9 are positioned by the holding parts 7. The underlying basic principle is in turn the different design of the holding parts 7, 9 of the two types of tools.
  • the positioning means 22 for the holding part 7 is formed by a recess (groove) 12a, in which a bar or a web 22a is seated. This engages in a recess of the holding part 7.
  • the holding part 9 is without a recess and is positioned by the adjacent holding parts 7. There may be gaps between the adjacent holding parts 7, 9.
  • the web 22 a may be integrally connected to the bar 1 or the holding part 7 of the needle 4.
  • FIG. 4 illustrates another embodiment of the invention. In this takes place the positioning of the tools 4, 5 of the tool set 3, as described above. Reference is therefore made to the previous description based on the same reference numerals.
  • the tools 4, 5 find their way FIG. 4 With their narrow sides 12, 14 no contact with the bar 1. Rather, suitable projections, for example in the form of feet 23, 24, 25, 26 are provided which engage in longitudinal grooves 27, 28 of the bar 1.
  • the longitudinal grooves 27, 28 extend parallel to the longitudinal direction B and thus transversely to the recesses or grooves 16. The longitudinal grooves 27, 28 can cut through the recesses 16 or run through ungrooved regions of the support surface 17.
  • the length of the feet 23 to 26 is sized to determine the height position of the tools 2. This is especially the case FIG. 5 out.
  • the feet 25, 26 lie with their front sides on the bottoms of the Longitudinal grooves 27, 28 at. The same applies to the tools 4 of the first type.
  • FIGS. 6 to 8 Another modified embodiment of the invention illustrate the FIGS. 6 to 8 in their entirety.
  • both the in FIG. 7 illustrated tool 4a of the first type as well as the tool 5a of the second type associated with positioning.
  • the positioning means are formed by the bar 1 'by grooves 16-4, 16-5 or other suitable recesses.
  • the grooves 16-4 form a first group of positioning means which cooperate with portions 29 of the holding parts 7a of the tools 4a of the first type.
  • the upper narrow sides form part of the support surface 17-5.
  • the narrow sides 14a of the tools 5a find their abutment on them.
  • the grooves 16-4 are spaced at twice the pitch.
  • the slit walls delimiting them have a thickness which substantially coincides with the thickness of the holding part 9a.
  • the holding part 9a of the tool 5a has a small height in a portion near its foot 19, which is to be measured in the direction H perpendicular to the longitudinal direction W.
  • the holding part 7a of the tool 4a has a comparatively greater height.
  • the height difference between the two holding parts 7a, 9a preferably corresponds to the depth of the groove 16-4.
  • the holding parts 7a, 9a also have different heights.
  • the holding part 9a is here provided with a portion 30 which is adapted to engage in the grooves 16-5. These are offset from the grooves 16-4 by one pitch, ie a little more than a thickness of the holding part 7a and / or 9a.
  • the upper narrow sides of the web walls delimiting the grooves 16-5 lie in a common plane and form a bearing surface 17-4.
  • This support surface 17-4 is preferably with the support surface 17-5 in a plane. It serves to support the narrow sides 12a of the tools 4a.
  • the grooves 16-5 may be formed in or on a separate part 31 of the bar 1 ', which is inserted into a wide flat longitudinal groove of the bar 1' and positioned there as desired. Otherwise, the previous description applies accordingly. In particular, it is possible to position the feet 19, 20 separately in the FIG. 6 not further illustrated recesses to provide, for example, a longitudinal groove. Furthermore, grooves corresponding to the longitudinal grooves 27, 28 and feet provided for supporting the tools 4a, 5a corresponding to the feet 23 to 26 may be provided to position the tools 4a, 5a in their height. Furthermore, the combination with features of the previous embodiments is possible. For example, the grooves 16-5 may be omitted if the tools 5a have a consistently low land height corresponding to the tools 5. They are then positioned by the tools 4. Conversely, the grooves 16-4 can be omitted, the tools 4a are then positioned by the tools 5a.
