FIELD: weapons.

SUBSTANCE: invention concerns projectile devices utilising power of strained solid body and can be applied in design and construction of projectile weapons, particularly bow and cross-bow. Round assembly with divided peripheral surfaces for projectile device is intended for projectile device mounting on loose end of resilient element in projectile device. Assembly features peripheral surfaces for passage of bowstring and at least two strings of compound pulley. Peripheral surface for bowstring is separated from the closest peripheral surface for string of compound pulley by distance sufficient for compound pulley string not to stand in the way of released projectile.
