US Patent 11672206 Baler with needle overload protection

A baler including a needle yoke driven via a needle coupling device including a connection member pivotally mounted around a fixed pivot axis for swinging around the fixed pivot axis. The swinging corresponds to movement of the needle yoke. The connection member is cooperative with the needle yoke by (i) a shearbolt adapted to transfer a force from the connection member to the needle yoke during a forward movement and (ii) by a protrusion, formed at one of the connection member and the needle yoke, to abut against the other one of the connection member and the needle yoke during a backward movement of the needle yoke.
