Abstract
A wedge-type breechblock is provided for a weapon having a barrel that recoils relative to a cradle, the barrel having a bore with an axis, and a breech plate. The breechblock includes a closing wedge for arranging in the breech plate such that the closing wedge can be displaced transverse to the axis of the bore. A pin-type carrier, through a control lever and a breech mechanism shaft, activates the closing wedge. An ascending curved track is located on a guiding device, and guides the pin-type carrier during a counter-recoil motion of the barrel from an intake region to a highest point, so that the control lever is pivoted during the counter-recoil motion of the barrel and the breech mechanism shaft is turned to move the closing wedge to an opened position.
