A machine for slotting hexagonal heads of bolts at right angles to oppositely located edges of the heads. The machine includes a rotatable driven conveying wheel having radially arranged grooves for receiving the shafts of bolts therewith; an alignment device, for aligning the edges of the bolt heads in a predetermined position relative to the conveying plane; a clamping device, for clamping the shafts of the bolts relative to the grooves of the conveying wheel over a predetermined conveying or clamping region of the bolts; a cutting device arranged relative to the clamping region of the bolts for cutting a slot into the heads of the bolts during transport thereof through the clamping region; and a device for removing burrs resulting on the bolt heads during cutting of the slots. The alignment device includes a guide surface movable transverse to the plane of conveying by a predetermined extent into the region of movement of the heads of the bolts, and, as seen in the conveying direction, is located a predetermined amount before the beginning of the clamping region, which follows in the conveying direction. A friction member is provided ahead of the burr removal device and extends over a predetermined length in the direction of conveying for the purpose of rotation of the bolt by 90.degree.. The guide surface is formed by a body which is adjustable in the conveying direction of the bolt at the end of an arm of a two-arm lever, one end of which is pivotally journalled about a bolt, and the other end of which is provided with an adjustable abutment and is engaged effectively by a biasing spring.
A machine for slotting the heads of bolts having hexagonal heads with at least one side and with a region of movement, said machine comprising:
