Lace makers in West Europe and North America prefer to set patterns on wide flat pillows instead bolsters that are so popular in Eastern countries. In western lace making technique a pillow stays practically immovable. It makes possible to held the pillow on knees and use the simplest contrivances to fix its incline.
Nevertheless a flat pillow as well must have three degrees of freedom to deliver the following manipulations with pillow:
- – rotating around the center of a pillow;
- – inclining towards a lace maker;
- – lifting a pillow along vertical axe.
That is why rests are invented for flat rests too. A study table is inconvenient as rest since it is immovable in the room. It would be better if a lace maker had an independent rest for the pillow. Such a rest naturally could be set at the best illuminated place of the room.
Multiple examples of pillow rests are shown in books[5] and in the World Wide Web. These have one of prototype:
- – rests (“horse”, “goat”) having four leg;
- – reading (music) stands having one leg.
During experiments with equipment for lace making authors of the book made a rest for a disk pillows too. Our rest (Fig.2.38- Fig.2.40) provides regulations:
- – shift 60 to 80 cm (24 … 32 inches) along vertical axe;
- – swinging 0 to 600 around horizontal axe.
The bearing post moves between two flats. The height of a disk is fixed by means of squeezing the flats. The incline of a disk provides a hinge braked with a rubber washer. The steadiness of the rest is guaranteed by size of platform. There is enough room for lace maker’s feet. The bearing post is fastened with three inclined flats.
