Abstract: Collagen membranes are formed from porcine rinds (i.e., pig skins) for us in a variety of applications and, most preferably, for wrapping food products, such as hams and the like. First, after removing skins from the porcine, the skins are promptly frozen. In later processing, the rinds are thawed and then enzymatically defatted. Then, a quick alkalinic hydrolyzation is performed on the rinds. Then, an acidic hydrolyzation is performed on the rinds. The rinds are then ground into a gel-like fluid mass. Finally, the fluid mass is extruded, sheeted and dried into a collagen membrane. The collagen membrane produced can be, in preferred embodiments, used for wrapping food products, such as hams.

Abstract: A rotary hoop knife splitting machine, particularly for splitting skin free from hair, includes a knife with a cutting edge, a feeding device arranged in front of the cutting edge, wherein the feeding device includes a transport gap defined by a base and a driven transport roll, and a feeding gap defined by another base and a driven feeding roll. The transport gap and the feeding gap are arranged closely one behind the other. The transport roll has a diameter which increases from the middle toward the ends. The transport roll is composed of two parts connected to each other in an articulated manner so as to rotate together. The two parts are mounted such that a surface line of the transport roll at the transport gap is a straight line extending parallel to the base.

Abstract: The present invention relates to a braider (1) comprising a device for controlling the thread lever (10). Said braider is formed by a curved path (30) that is closed in a circular ring-shaped manner, a sliding block (31) appurtenant thereto and a reverse gear (20) by means of which the direction of rotation of the drive motor is reversed in such a way that the group of the upper delivery bobbins and the group of the lower delivery bobbins rotate in opposing directions. The aim of the invention is to enable such a braider (1) to have a higher ceiling speed.
