A device for feeding the leader of a paper web from below to a rolling machine roll, with a number of guide plates which direct the web leader upward and which, viewed in the web running direction, are arranged increasingly more steeply and eventually vertically, additionally with blowing organs that feature each a hollow body arranged transverse to the web running direction and a number of nozzles arranged in the web running direction, and which, viewed in web running direction, are arranged each between two overlapping guide plates. The invention is characterized in that at least the blowing organ which, in the web running direction, precedes the first vertical plate features turbulence-generating nozzles.

A cutting device for a winding machine for winding a web of material, particularly a paper web, the winding machine having two support rollers, one of the support rollers being partially wrapped by the web of material which is advanced upward from underneath the support rollers and introduced into a space between the support rollers, to be wound into a finished roll which rests on the winding bed formed by the two support rollers. A tiltable cutting device includes a blade, a blade carrier, a connecting link, and a support structure. The blade carrier and the support structure are pivotally connected to each other by the connecting link in such a manner that the blade carrier can be tilted into a position in which the blade faces the web of material while the opposite end of the blade carrier rests against the outer surface of the unwrapped support roller.

A winding machine with receiving stations for winding rolls arranged on both sides of a roller, to which web-form material runs alternately (as viewed in machine transverse direction). On a machine frame there are arranged axially unslidable load rollers following one upon another over the usable machine width. The load rollers are movable with operating arrangement against the winding rolls. For the use of the load rollers it is merely required that there be selected those rollers which lie within the width of the corresponding web strip.

A clamping head is equipped with angular spreading bodies which engage a winding core. Impingement of the winding core end face on a stop moves the spreading bodies longitudinally on a bevel of the clamping head core against spring force, thereby spreading the spreading bodies so as to engage the inside circumference of the winding core. To that end, the clamping head features a sleeve-shaped part which centers the winding core and is provided with longitudinally extending slots for the angular spreading bodies. A shank of each spreading body, extends radially outward, forms at least indirectly the stop for the winding core end face. Longitudinally movable in the slot, the other shank of the spreading body has a projection which protrudes radially inward and interacts with the bevel of the clamping head core so as to cause the shank to move beyond the peripheral surface of the sleeve-shaped part as the projection runs onto the bevel. The clamping head secures the winding core in both nonpositive and form-fitting fashion in that the spreading body shanks dig into the winding core. It is distinguished by a design from components which are relatively simple to manufacture and of which the spreading bodies exposed to wear can be replaced easily.

Clamping head for winding cores

A clamping head is shown having a cylindrical portion engaging an interior portion of an associated winding tube and a collar or flange which axially abuts against the axial end face of the associated winding tube; extending axially between the cylindrical portion and the collar or flange is a conical portion of longitudinally extending serration; the teeth of such serration start, from the diameter of the cylindrical portion, beginning with a zero cross-section and increase toward the collar or flange with steadily increasing geometrically similar cross-section.

A winding machine for paper-core insertion is provided for the simultaneous, shaftless winding in two winding beds the strips of a web slit lengthwise. The machine has three support rollers generally arranged next to each other, and the web strips are alternately run into the winding beds. A winding frame with a core guide is associated with each edge of the wound rolls, which core guides have core grips. A transport device, positioned above the middle of the three support rolls, cooperates with an insertion assembly to transfer new paper cores into the respective winding beds. Alignment of all paper cores in unbroken sequence on the transport device ensures transfer of the paper cores of the proper width to the correct location. Each winding frame has an insertion device on either side of a separating plane defined by consecutive wound rolls. The insertion devices transport new paper cores to the appropriate core grips for transfer to the winding bed.

Winding machine for winding a web slit lengthwise

A winding machine is provided with three support rollers horizontally aligned with parallel longitudinal axes and cooperating to define winding beds therebetween. The support rollers are arranged for simultaneously winding the alternate strips of a web slit lengthwise into at least two wound rolls in alternate winding beds. Each sidewall or front surface of the wound rolls cooperates with a winding frame, which guides the wound roll. Ejection apparatus are provided for each of the wound rolls and are mounted generally vertically disposed above the middle support roller in the machine. Each ejection apparatus has at least one rocking lever with a pressure bar at its lower end for each of the wound rolls, which rocking levers are mounted on longitudinally displaceable carriages. The rocking lever pressure bar has a length less than one-half the width of the narrowest wound roll and contacts the wound roll to move it from the winding machine.
