ABSTRACT:
A briquetting machine for shaping a pulverized and/or powder material includes, on the downstream side of briquetting rolls, a pair of notching rolls provided with blades on their peripheral surfaces. The blades extend in the circumferential direction and/or the widthwise direction. The notching rolls are rotated in opposite directions in synchronization with the briquetting rolls, whereby a continuous strip of briquettes discharged from the briquetting rolls can be sheared and separated by the notching rolls. In an alternative embodiment of the present invention, in the aforementioned type of briquetting machine, the interval between the notching rolls is selected such that when the continuous strip of briquettes is bitten between the notching rolls and is not sheared nor separated but it is merely notched by the notching rolls. A briquette guide is disposed on the downstream side of the notching rolls. A divider consisting of a roll and blades mounted radially on the circumference of the roll is disposed on the downstream side of the briquette guide. The divider is rotated in synchronization with the briquetting rolls and notching rolls, whereby webs connecting the briquettes extruded from the notching roll can be separated at the notched positions.
