An apparatus for applying a fluid to a convolutely wound roll of web substrate is disclosed. The apparatus provides for a fluid applicator having a manifold and a first surface. The fluid is fluidly displaceable from the manifold to the first surface through at least one opening disposed therein. The convolutely wound roll of web substrate is disposable upon the first surface. The fluid is fluidly displaced from the first surface to the convolutely wound roll of web substrate.
摘要:
A gluing machine for gluing the final edge of a log successively comprising an introduction group of the logs one after the other into the machine, an unwinding group of the log associated with identification means of the final edge, an opening group of the final edge from the log, a glue transfer group onto the log and a rewinding group of the final edge onto the log, in which the unwinding group of the log comprises a pair of rollers arranged one on top of the other to make a passage for the log, the pair of rollers being selectively for the feeding and for the retention in rotation of the log, at least one inclined surface of free rolling of the log being provided downstream of the pair of rollers.

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:
An improved device for gluing the end flap of a log and a gluing method which can be implemented in a machine for producing logs, in which the logs (14), which come from a re-reeling machine, are fed to a gluing device (11) comprising in succession a bottom unwinding roller (16) and a top feed belt (17), and, immediately downstream of the unwinding roller (16), at least one stretch of inclined surface (21), of a pre-set length, followed by a vacuum-suction roller (24), set on top of which is a top roller (25), and then by a glue dispenser (27), there being provided on top of the unwinding roller (16) a blower element (19) for blowing an end flap (29) of the log (14) and, underneath, a photo-electric cell (20) for detecting the end flap (29), in which the log fed to the unwinding roller (16) is set with a position of the free end staggered by an angle (α), which is a function of the diameter of the log and of the pre-set length of the stretch of inclined surface (21), in such a way that, when the log thus positioned rolls on the inclined surface, it sets itself on the suction roller (24), with the free portion of the end flap (29) set exactly corresponding to the area of contact with the suction roller (24).
摘要:
A gluing unit for an end edge of a log and un method implementable in a machine for making logs, wherein the logs (14), which come from a rereeling machine, are fed towards a gluing unit (11) comprising in succession a lower unwinding roller (16), and an upper feeder belt (17) and, immediately downstream of the unwinding roller (16) at least two sections of sloped surface (21, 23), of pre-selected length, followed by a suction roller with vacuum, positioned above which is an upper roller (25), and then a glue dispenser (27), provided above the unwinding roller (16) being an element (19) for blowing a final edge of the log (14) and beneath a photocell (20) for detecting the final edge (21), provided for being surface (34) for evacuating the glued log, provided for being a timing unit (22) for positioning the free end according to an angle (α) depending on the diameter of the log and the pre-selected length of the sloped surface section (21, 23) in such a manner that the log thus located is positioned on the suction roller with its free end of the final edge thereof arranged at the zone of contact with the suction roller.
摘要:
A method for distributing glue on an end edge of a log, on a log, or on a core for logs which advances logs on a feed surface toward a glue reservoir wherein a fixed blade, coupled to a movable plate, distributes the glue from said reservoir to the log by conveying said plate upwards and discharging said glue to an upper free end of the fixed blade, returning said plate downwards, and passing said log over said fixed blade.
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).
