BUTI, SWITZERLAND V I l I 211m non Looms 7 Application filed. September 12, 1929, Serial N0. 392,219, and in Switzerland September 20, 1928.
This invention is intended to permit a suf ficient braking of the weftrthread winding of a pirnv for automatic silk-weaving looms. which passes through the centre-bore of the plrn.
7 It has been found that a thread which is braked on the periphery of the pirn and passed thereupon through the centre-bore of the pirn affords no satisfactory braking effect. This disadvantage is overcome by the present invention which provides a braking device in the centre bore of the pirn.
In the drawings:
Fig. 1 is a longitudinal section of theeimproved pirn,
Fig. 2 isa eros section on the line a-a of.
Fig. 3 is an elevation of the pirn.
In Figs. 1,2 and 3, lis a pirn through th central bore 3 of which runs the weft thread 2 winding off the pirn. In thecentre-bore 3 of the pir'n a braking device 4 is inserted. The device mav be pelt.- The weft thread passing through the hairsof the pelt is suit ablv braked in the centre-bore of the pir'n.-
WhatIc1aimis:-- I v I 1. 'A pirn for automatic silk weaving looms having a center bo're'serving as a: thread guide, and a braking device inserted-in the center bore of 'thepirnnconsisting of felt, said braking device being engageable with. the thread passable through the bore.
2. A weft pirn for automaticsilkweaving looms having a center bore serving as a weft thread guide. and braking. device in- .serted directlv in the center bore intermediate the ends thereof. said braking device heing engageable with the weft thread passable 1 signature.
