По основному авт. св. 414076 известно защитное устройство, у которого блоки конечных участков барабанов вьтолнены в виде усеченных конусов с вершинс1ми, направленными в противопо- 5 ложные стороны, соотношение диаметров оснований которых выбрано в зависимости от ТОЛЩИНЫ наматываем&й ленты дл выравнивани окружной скорости на периферии этих барабанов по мере нама- 0 тывани наних этих лент 1J.According to the main author. St. 414076 a protective device is known in which the blocks of the end sections of the drums are made in the form of truncated cones with vertices directed in opposite directions, the ratio of the diameters of the bases of which is chosen depending on the THICKNESS of the band to align the circumferential speed on the periphery of these drums as putting on these tapes 1J.
Однако зто устройство предполагает применение только металлических лент.However, this device involves the use of only metal tapes.
Цепь изобретени - повысить надежность защиты при использовании неме- |5 таллических лент.The chain of the invention is to increase the reliability of protection when using non-tall tape.
Дл этого оно снабженорасположенными по обе стороны гибкой св зи ос ми , закрепленными на фартуке станка, и свободно размещенными на них втул- 20To do this, it is equipped with axes located on both sides of the flexible coupling, mounted on the apron of the machine, and placed freely on them.

На фиг. 1 изображено предлагаемое устройство, общий вид; на фиг. 2 разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.,FIG. 1 shows the proposed device, a general view; in fig. 2, section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.,
Устройство содержит кронштейны 1 и 2 со свободно вращающимис барабанами 3 и 4 с закрепленными на одной оси блоками 5 и 6, которые имеют форму усеченных конусов.30The device contains brackets 1 and 2 with freely rotating drums 3 and 4 with blocks 5 and 6 fixed on the same axis, which have the form of truncated cones.
На каждый барабан 3 и 4 намотаны ленты 7 и.8. Один конец каждой ленты жестко крепитс к барабану, другой на подвижном фартуке станка. При этом ленты 7 и 8 выполнены из неметаллического материала.On each drum 3 and 4 tapes 7 and 8 are wound. One end of each tape is rigidly attached to the drum, the other on the movable apron of the machine. When this tape 7 and 8 are made of non-metallic material.
Конические блоки 5 и 6 кинематически св заны с тросом 9, пружинойConical blocks 5 and 6 are kinematically connected to cable 9, a spring
10и составными элементами дополнительного механизма 11, которьм оснащен фартук станка.10 and the components of the additional mechanism 11, which is equipped with an apron of the machine.
Дополнительны) механизм 11 имеет направл ющие дл плавающих губок 12 и 13, содержащие оси 14 и 15 с свободно размещенньиии втулками 16 и 17, которые служат ДЛЯ жесткого креплени на них концов троса 9. Пружина 10 служит ДЛЯ нат жени троса 9 и защитных лент 7, 8 через оси 14, 15 и втулки 16, 17.Additional mechanism 11 has guides for floating jaws 12 and 13 containing axles 14 and 15 with loosely placed sleeves 16 and 17, which serve to firmly attach the ends of the cable 9 to them. The spring 10 serves to tension the cable 9 and protective tapes 7 , 8 through axles 14, 15 and bushings 16, 17.
Защитное устройство работает следующим образом.The protective device operates as follows.
При движении фартука станка слева направо его дополнительный механизмWhen the apron of the machine moves from left to right its additional mechanism
