The present invention includes a first weight scale that senses first information necessary when acquiring the residual amount of a first composite material sheet wound on a first support rod; a second weight scale that senses second information necessary when acquiring the residual amount of a second composite material sheet wound on a second support rod; a first cutting part for cutting the first composite material sheet; a second cutting part for cutting the second composite material sheet; a pressure-bonding mechanism that pressure-bonds the first composite material sheet and the second composite material sheet; and a control device that controls the first cutting part, the second cutting part, and the pressure-bonding mechanism.

Provided is a sheet supply device capable of reliably joining sheets by accurately transmitting force for joining the sheets. A joining mechanism includes a pressing roller that presses a sheet of a supply side roll against the outer peripheral surface of a standby side roll; and a moving unit that supports the pressing roller such that the pressing roller is configured to approach and move away from the standby side roll supported by a support shaft disposed at a splice position in the radial direction of the standby side roll. The moving unit supports the pressing roller such that the center of the pressing roller is movable on a straight line passing through the center of a rotation shaft and the center of the support shaft disposed at the splice position.

A device for splicing and continuously providing an outgoing film web includes a splicing unit for splicing a first or a second incoming film web to the outgoing film web, and a clamping unit and an intermediate film storage for the outgoing film web.

The splicing unit includes a first sealing jaw with a first holding device for the outgoing film web, and a first cutting device for severing the outgoing film web in the region of the first sealing jaw. The splicing unit includes a second sealing jaw with a second holding device alternately for the first or the second incoming film web, and a second cutting device for severing this incoming film web. The sealing jaws with their respective holding devices can be displaced relative to one another out of the region of action of their first and second cutting devices into their mutual region of action.

The present invention relates to a method to remove an adhesive label (22) from a bobbin (28), the bobbin including an end portion (24) and an outer surface (25), the method including: providing a bobbin of a coiled sheet closed by an adhesive label positioned on top of the end portion of the coiled sheet (26) to attach the same to the outer surface of the bobbin; locating the adhesive label; applying a sucking force to the location of the adhesive label so as to detach the adhesive label and the end portion of the coiled sheet from the bobbin; and cutting a part of the detached end portion including the adhesive label from the bobbin. The present invention also relates to an apparatus to detach an adhesive label from an end portion of a coiled sheet in a bobbin, the adhesive label being located between the end portion and an outer surface of the bobbin.

A supply device (3) for supplying substrate strips (10, 10′; 11, 11′) to a double-belt press (2) for pressing the substrate strips (10, 10′; 11, 11′) together includes unwinding stations (4, 5) each having an unwinding shaft (6, 7) for receiving a substrate strip roll (8, 9) and serving to unwind the substrate strips (10, 10′; 11, 11′) from the substrate strip roll (8, 9), at least one of the unwinding stations (4) having a force-measuring device with a measuring shaft (16, 17) around which one of the substrate strips (10, 10′; 11, 11′) can be wrapped, an auxiliary shaft (18, 19) being assigned to the measuring shaft, wherein the auxiliary shaft (18, 19) and the measuring shaft (16, 17) of the unwinding station (4) are moveable relative to each other between a guiding position for guiding the substrate strip (10, 10′; 11, 11′) from the roll of the substrate strip rolls (8, 9) through a gap between the measuring shaft (16, 17) and the auxiliary shaft (18, 19) and an operating position defining a pre-defined and/or pre-definable wrap angle (χ) of the substrate strip (10, 10′; 11, 11′) around the measuring shaft (16, 17) by an adjusting drive.

The present invention relates to the field of SMT splicing belt processing equipment, and more particularly to a bonding machine for new and old SMT splicing belts. The machine comprises a supporting plate for supporting the old and new splicing belts, conveying devices for conveying the old and new splicing belts toward one another, and a bonding mechanism for bonding the old and new splicing belts together, the conveying devices and the bonding mechanism both being connected to a controller.

Devices, methods, and systems for splicing a trailing edge of an outgoing roll with a leading edge of a replacement roll with a lapless butt splice on-the-fly during converting and printing production. A first strip of adhesive tape may be placed partially under the leading edge, such that a portion of the adhesive tape remains exposed beyond the leading edge. The replacement roll may be accelerated to match the speed of the outgoing web's movement, a trailing edge of the outgoing web may be cut free from the outgoing roll, and the trailing edge of the outgoing roll may be positioned over the exposed portion of the adhesive tape. A second strip of adhesive tape may be applied over the leading edge and trailing edge using a splicer roller timed to apply the tape when the edges pass proximate to the splicer roller.

A web splicing apparatus is disclosed that includes a web unwinding unit configured to hold a running web material roll and a new web material roll and to unwind webbing from the running web material roll and a web splicing unit operable with the web unwinding unit to selectively splice the webbing of the running web material roll with webbing of the new web material roll. The web splicing unit further includes a cutting assembly configured to selectively sever the webbing of the running web material roll, a web deflection device, an actuator system configured to linearly translate the web deflection device in a first direction and a second direction opposite the first direction, and a locking mechanism operable in a locked state and an unlocked state to selectively prohibit and enable movement of the web deflection device in the first direction and the second direction.
