The present invention discloses a tape dispenser which includes a body having a downward facing concave space at a bottom thereof, a cutting blade mounted to the body and positioned in the concave space with an cutting edge recessed in the concave space, a groove member being able to move vertically between a first and second location, at the first location, the groove member being partially submerged in the concave space and pocketing at least a portion the cutting blade for cutting a piece of tape, at the second location, the groove member being downwardly away from the bottom of the body for threading a piece of tape through a gap formed between the groove member and the bottom of the body, a side plate attached to an end of the groove member, the side plate being slidably accommodated in a hollowed space formed inside the body, the side plate having a slot for retaining a spring to urge the side plate to slide downwardly resulting in the groove member to move from the first location to the second location, and a stopper situated within the slot and at an upper end of the spring, the stopper being fixed to the body and preventing the side plate from being completely pulled out of the hollowed space.

The invention relates to a device and a method for manipulating a fibrous web (10). The device comprises at least one blower (21A, 21B) provided with a flow-preventing element (24A, 24B) which is arranged to produce at least one blow (26A, 26B) substantially in the direction of the fibrous web (10), and a friction element (28) against which the fibrous web (10) is arranged to be pressed at least partially from the effect of said blow (26A, 26B) and flow-preventing element (24A, 24B) to apply a friction force resisting the motion of the fibrous web (10) to the fibrous web (10). According to the invention, the blow (26A, 26B) is directed substantially away from the friction element (28) and the friction element (28) comprises a surface profile which is arranged such that, from the effect of said at least one blow (26A, 26B), a continuous vacuum is created on the surface of the fibrous web (10) on the side of the friction element (28). Due to its intensified friction effect, the device according to the invention is applicable especially for board and, by means of it, it is possible to form e.g. an air cutting device in the tail-threading section of a board machine.

Methods and apparatus to form tear-off paperband composites that adhesively attach a paper web to an empty web spool. In some embodiments, the paperband composite is applied in several layers to an empty web spool, each layer suitable for fixedly attaching a paper web to the empty spool. Multiple layers of paperband composite allow for use during multiple turn-up procedures with one layer of paperband composite used per turn-up procedure. In some examples, the paperband composite may be applied to a paper spool tangentially along the spool face and perpendicular to the axis of rotation of the spool. In other examples, the paperband composite may be spirally wrapped around the paper spool.

The rewinding machine includes a first winding cradle, formed between a first winding roller, a second winding roller and a third winding roller and a second winding cradle formed between the first winding roller, the second winding roller and a fourth winding roller. The first winding roller and the second winding roller define a nip through which nip the winding cores, around which the web material is found, pass and the web material is fed towards a roll being formed in the second winding cradle. A severing member is furthermore provided, acting on the web material between a winding core and the nip, to sever the web material thus generating a tail edge of a completed roll and a leading edge of a new roll to be wound.

A system for providing a web of inflated containers includes a conveyance system, a detachment arm, and a controller. The conveyance system has an operative mode in which the web is advanced along a path of travel by counter-rotating members having a nip through which at least a portion of the web passes and (ii) an idle mode. The detachment arm is positioned beside the path of travel downstream from the conveyance system. The detachment arm has a separator end to engage the web in the path of travel. The controller is programmed to operatively control the conveyance system to move to: (i) the operative mode to advance the web by a predetermined number of containers and (ii) the idle mode in which a transverse detachment line of the web is aligned with the separator end of the detachment arm.

Paperband composites for transferring a paper web from a full web spool to an empty web spool. In some embodiments, the paperband composite is applied in several layers to an empty web spool, each layer suitable for fixedly attaching a paper web to the empty spool. Multiple layers of paperband composite allow for use during multiple turn-up procedures with one layer of paperband composite used per turn-up procedure.

A first motor causes a first conveying roller pair to rotate, and a second motor causes a second conveying roller pair and an aligning rotational member to rotate. A control portion temporarily stops the first motor each time a sheet member reaches a position at which the sheet member is subjected to punching. Each time the sheet member reaches the position at which the sheet member is subjected to punching, the control portion continuously operates the second motor if the sheet member unreaches a position at which the sheet member is nipped by the second conveying roller pair, and otherwise temporarily stops the second motor.

A method of preparing an elongate web of sheet material for dividing into discrete stacks of web portions after reeling the web onto a drum is provided. The method includes forming transverse discontinuities in the web at spaced intervals corresponding to edges of the discrete stacks to be formed, the intervals progressively increasing along the web so that the discontinuities form angularly-aligned groups when reeled onto the drum.
