3.6. Work place for untwisting of thread
Three operations of the thread split are performed sequentially at the same work place in domestic conditions. On this reason it would be better to combine three contrivances at a single revolving platform. The roundabout mechanism of the integrated workplace is presented here (Fig3.30…Fig.3.32).
The platform consists of two disks – unmovable 1 and revolving 2. The disk 2 rests on four rollers 3. Four poles are attached on the movable disk 2. The platform 5 of the contrivance for thread split is set on the poles. This contrivance consists of the units 6 and 7 that are described in the paragraph 3.3.
The contrivance 8 for rewinding thread to the clew is mounted on the disk 2 too. The contrivance 9 intended for rewinding of thread to the saving spool is attached to the platform 5 and is supported with the bracket 10. The box saving the clew is set on the platform 5 as well.
A lace maker turns to herself one of the contrivances that is needed now. The rotation is performed easily since the rollers between disks are ball-bearings.
When the contrivance is chosen, the upper disk position is fixed with the brake lever that is set on the disk 1 (Fig.3.30).
The lever is pulled normally with the spring to a gap between the disks 1 and 2. The disk 2 is stopped due to friction strength that is obliged to the rubber strip attached to inner side of the lever. When the disk 2 is to be turned, one must pull the lever with the handle out of a gap.
When the next contrivance is chosen one must relax the lever. The spring will move it at the former place.
