Systems for processing material, taping stations to apply tape to one or more rolls of material, and methods of processing material are disclosed. A system for processing material includes a winding station and a taping station. The winding station includes a winder to wrap material around a mandrel to produce one or more rolls of material. The taping station is arranged downstream of the winding station to receive the one or more rolls of material therefrom and apply tape to the one or more rolls of material.
摘要:
A device for distributing glue on an end edge of a log, on a log or on a core for logs comprising a feed surface (16) of logs or cores (15) towards a glue distribution area, wherein the device comprises a container (13) containing glue (12), wherein disposed inside the container (13) is a fixed blade (18) with one free end (22) facing upwards at the level of an interrupted section (19) of the feed surface (16) on which the logs or cores (15) travel, one behind another, the fixed blade (18) being associated with a plate (27) movable from the bottom upwards, and vice versa, which conveys the glue (12) to the level of an upper free end (22) of the fixed blade (18), discharges it on the free end (22) and returns towards the bottom of the container (13), the moving plate (27) having, at an upper end thereof, an area to collect glue (28, 29) in the container (13) and to discharge glue on the fixed blade when it is taken to the level of the upper end (22) of the fixed blade (18).
摘要:
A gluing unit for one terminal edge of a log and a method applicable inside a machine for the realisation of a log, in which the logs (14) coming from a rewinding machine are fed towards a gluing unit (11) comprising in sequence a lower unwinding roller (16), and a upper feeder belt (17, 26), and immediately downstream of the unwinding roller (16) at least one section of a sloping plane surface (21, 23) of a pre-established length, followed by a vacuum suction roller (24) above which is positioned an upper roller (25), and then a glue distributor (27), an element (19) being envisaged above the unwinding roller (16) which blows on a terminal edge (29) of the log (14) and underneath a photocell (20) to detect the final edge (21), an evacuation surface (34) for the glued log being envisaged, wherein the log fed by the unwinding roller (16) is placed with the position of the free end out of alignment by an angle (α) according to the log diameter and the pre-established length of the sloped surface section (21, 23) so that the log in this position, rolls down the sloped surface (21, 23) to position itself on the suction roller (24) with its free end of the final edge (29) placed exactly in correspondence with the contact zone with the suction roller (24).
摘要:
A device for gluing the tail end of a reel of wound web material including conveying means for moving the reel, unwinding means for unwinding the tail end of the web material, a dispenser of glue for applying the glue to the reel, and means for rewinding the tail end after the glue has been applied. The dispenser includes an upwardly oriented aperture from which the glue is dispensed and includes a container for the glue with the upwardly oriented aperture and a moving member positioned inside the container which is immersed in the glue contained in the container and moved towards the upwardly oriented aperture in order to dispense the glue to the reel as it rolls over the aperture.

A method for securing a web end of a paper web on a first drum during a change of drum, the method includes passing the web end through a nip between a Pope roller and the second drum and applying adhesive to an area of the web end on a downward-rotating area of the Pope roller after the web end is passed through the nip.
摘要:
A nonadhesive phase-change material application apparatus for bonding the tail of a convolutely wound log to the body is provided. The nonadhesive phase-change material application apparatus has at least one nonadhesive phase-change material applicator that defines a cavity conveying a volume of nonadhesive phase-change material from a reservoir to an application site.
摘要:
A winder for winding a web to produce a rolled product is provided. Included in one exemplary embodiment is a plurality of independent winding modules. The winding modules may be configured to wind the web to form a rolled product by center winding, surface winding, and/or combinations of center and surface winding. In accordance with the present disclosure, at least one tail sealing apparatus is present in the system. The tail sealing apparatus includes an applicator device that transfers adhesive to a web being wound prior to completion of the roll. In one embodiment, the applicator device remains in contact with the wound roll during the completion of the winding cycle in order to have an ironing effect on the finished roll.
