|
1/ | 28 | . | . | . | by creating and then eliminating back-lash between hooks and knives |
|
1/ | 30 | . | . | . | wherein all the hooks are disengaged from the knives, and selected hooks then re-engaged |
|
1/ | 32 | . | . | . | wherein all the hooks are engaged with the knives, and unselected hooks then disengaged |
|
1/ | 34 | . | . | Arrangements wherein warp threads pass one another at different heights to avoid congestion |
|
1/ | 36 | . | . | Card- or chain-saving arrangements, e.g. cross-border dobbies |
