A wire locking mechanism () for a reinforcement bar, rebar, wire tying device (), the locking mechanism comprising () a holding member () and a counter-holding member () arranged to engage respective and opposite sides of a wire () to releasably hold the wire () in a locking position, where a holding force exerted on the wire () by the holding member () is normal to a holding plane (A), wherein the holding member () is supported on a first end of an excentre arm (), the excentre arm () being rotatably supported on a first shaft () to rotate (R) about an excentre arm center of rotation (), wherein the holding member () is arranged distanced (D) along a first axis (A) from the excentre arm center of rotation (), the first axis (A) forming an acute angle (A) with the holding plane (A) when in the locking position.

Rebar tying device comprising a wire locking mechanism and a control unit for controlling the wire locking mechanism

Described herein is an arrangement () for guiding a wire in a wire binding machine (), wherein the arrangement () comprises a guide member () and a first spring () arranged to act with a first spring force against the guide member (), wherein the guide member () is arranged to bear against the wire and act against the wire with said first spring force in order to guide the wire during a wire binding process when the wire moves relative to the guide member (). The guide member () is arranged so that a movement of the guide member () substantially away from the wire is allowed in order to reduce friction forces between the guide member () and the wire during the wire binding process, so that locking of the wire against the guide member () is prevented. Also described herein is a wire binding machine () comprising an arrangement ().
