Abstract: A cross cutter for a web of goods comprises 2 coupled cutter rolls which are driven at the moment of cutting in synchronism with the webs of goods. The driving of the rolls is carried out by a driving motor, an adjustable asymmetrical coupler mechanism and a mechanism for controlling the number of revolutions per unit time of the driving motor. The cutter rolls are directly driven by the driving motor and parallel to the asymmetrical mechanism and the control mechanism is receptive of the actual number of revolutions as a control input from the asymmetrical mechanism.

Abstract: An apparatus for rotatably mounting a web on a spool including two chucks, each carried by a shaft which is rotatably mounted in a mounting frame, and each having a mandrel axially delimited by a stop flange and on which the spool is releasably clamped. Each chuck has a stripping ring disposed around the mandrel between the stop flange and a spool to be received, and configured to be axially slidable therealong, and wherein the ring comprises an axially extending collar. An actuating device is mounted on the mounting frame and is coactive with the stripping ring to effect the axial displacement thereof away from the stop flange so as to strip the spool from the mandrel.

Abstract: A device for the pressing of gummed labels or foils against objects which are moved along a straight or curved path, comprises one or more pressing elements disposed one behind the other and movably advanced in synchronism with the objects along a path that is convexly curved with respect to the first path. Each pressing element has a pliable pressure pad disposed at the level of the area which is to be provided with the foil and situated at varying distances from the pressing element. The pressure pad comprises a plurality of elements disposed side by side, which independently of one another exert a point or line pressure during the pressing action.

Abstract: An apparatus for unwinding rolls of sheet material and for adhering the end of one roll to the beginning of the next at full running speed, without interruption. Means are also provided to permit operation with rolls of different widths and even with two narrow rolls alongside one another. A support which can be operatively positioned between two such narrow rolls can be moved laterally out of the way to take up an end-supporting position when a single wide roll is being unwound.
