Abstract

In a bar with modules for tufting tools, in particular a needle bar with needle modules, in which the tufting tools (3) are cast at one end into a plate-shaped basic body (1) of the module, at least one groove (9) running horizontally is worked in the bar (4). There extends from a plane face (2) of each module at least one moulding (7; 8) which projects perpendicularly to this face (2) and which engages into the groove (9) of the bar (4) and, alone or jointly with further mouldings (7; 8), holds the respective module fixedly in terms of rotation in the bar (4).

Claims

1. A bar with modules for tufting tools, said bar comprising a first face and a composite, horizontally extending groove formed in said first face of said bar, said modules comprising a module body, tufting tools cast into an end of the module body, a first plane face and a second plane face, said module being provided with at least one continuous bore extending through said module from said first plane face to said second plane face, said module further comprising a first moulding extending from said first plane face and a second moulding extending from said second plane face, said first and second mouldings being operable, when either one engages the groove formed in said bar and a fastening screw passing through the bore in said module is screwed into said bar, to hold said module fixed against rotation relative to said bar.

2. The bar with modules claimed in claim 1 wherein said groove and said first and second mouldings have rectangular cross sections.

3. The bar with modules claimed in claim 2 wherein said modules further comprise a collar positioned annularly around the bore and extending from said first plane face, wherein a threaded blind hole is provided in said bar and wherein a recess is provided in said bar, coaxially surrounding the recess, for receiving said collar.

4. The bar with modules claimed in claim 1 wherein said groove has the form of a feather key groove and said first and second mouldings have the form of feather key.

5. The bar with modules claimed in claim 4 wherein said modules further comprise a collar positioned annularly around the bore and extending from said first plane face, wherein a threaded blind hole is provided in said bar and wherein a recess is provided in said bar, coaxially surrounding the recess, for receiving said collar.

6. The bar with modules claimed in claim 1 wherein said modules further comprise a collar positioned annularly around the bore and extending from said first plane face, wherein a threaded blind hole is provided in said bar and wherein a recess is provided in said bar, coaxially surrounding the recess, for receiving said collar.

7. A bar with modules for tufting tools, said bar comprising a first face and a composite, horizontally extending groove formed in said first face of said bar, said groove having a first portion, adjacent to said first face, which is triangular in cross section and a second portion extending from said first groove portion further into said bar, said modules comprising a module body, tufting tools cast into an end of the module body, and a first plane face, said module being provided with at least one continuous bore extending through said module from said plane face to an opposed face, said module further comprising a first moulding extending from said first plane face, said moulding having a triangular cross section and being operable, when it engages the groove formed in said bar and a fastening screw passing through the bore in said module is screwed into said bar, to hold said module fixed against rotation relative to said bar.

8. The bar with modules claimed in claim 7 wherein said modules further comprise a second plane opposite said first plane face and a second moulding having a triangular cross section extending from said second plane face, opposite said first moulding.

9. The bar with modules claimed in claim 7 wherein said modules further comprise a collar positioned annularly around the bore and extending from said first plane face, wherein a threaded blind hole is provided in said bar and wherein a recess is provided in said bar, coaxilly surrounding the recess, for receiving said collar.

10. The bar with modules claimed in claim 8 wherein said modules further comprise a collar positioned annularly around the bore and extending from said first plane face, wherein a threaded blind hole is provided in said bar and wherein a recess is provided in said bar, coaxially surrounding the recess, for receiving said collar.

11. The bar with modules claimed in claim 6, 3, 5, 9 or 10 wherein said collar and the recess in said bar have a cooperating fit which positively locates said module relative to said bar.
