Abstract: The present invention relates to a holding system for holding sheet material for plotters characterized in that it comprises at least one substantially tubular side holding element (1), at least part of the external surface (2) thereof being tapered. Furthermore, said side holding element (1) comprises a longitudinal opening (7) and has internal chamfers at one of its ends (4). As a result of the thickness and the tapering of the external surface thereof, the side holding element hold the sheet material and, simultaneously, ensures that there is a gap between the winder tube and the sheet material wound on said tube, which facilitates its removal from the tube.

Abstract: To automate the preparation of a replacement paper roll for flying roll changing, initial layer portions of web material from the replacement paper roll and which, typically, are damaged, are rolled on a scrap roll (2) to form scrap material windings thereon. In a first moving step, the scrap roll (2) is placed in engagement with the replacement paper roll to wind scrap material thereon. When a sensing element (22) senses that the paper is suitable for printing, the scrap roll is moved away from the replacement roll (1) and into a preparation or processing position (FIG. 11). At that processing position, two spaced axially extending perforation or tear lines (4, 5) are formed in the beginning portion. In a third moving step, the beginning portion is placed in engagement with the paper roll by moving the scrap roll back towards the replacement roll and, preferably, adhered thereto temporarily by a holding adhesive.

Abstract: To prepare an initial portion (41) on a replacement roll (4) of a substrate web, for example a printing paper web, for flying pasting, the new roll (4) is rotatably supported in apredetermined position. An adhesive application and cutter structure (5) is then placed in operative association with the roll. An initial portion (41) of the web is rolled off from the new roll, positioned on the support plate, and, in one operating step, an end, which may be jagged, is cut off and, inwardly of the cut edge (42), a perforating or tear-off line (43) is formed, to leave, between the cut edge and the tear-off line, a tear-off section (44). The web can then be repositioned on the plate (6) and a connecting adhesive (19) is applied to the upper side of the web, for subsequent flying pasting against a moving expiring web, for example, as well as a holding adhesive, applied in the inside of the tear-off section (44), so that the end portion (41) is securely attached to the roll.

Abstract: When a web of packaging material is fed to a folding turret (11), it is intended to change the web of material when the reel is empty with as little manual labour as possible. For this purpose, there is provided a severing and connecting unit (17), in which a running-off web (15) is automatically severed and connected to a connecting web (16) which is held ready. In order to join the webs in the proper position, a marking (mark 43) of the running-web (15) is scanned while the conveying speed is greatly reduced. After the marking has been detected, the web is stopped and the severing cut is applied while it is simultaneously joined to the connecting web (16) which is held ready precisely in the proper position. During this change of webs, the folding turret (11) can continue to operate, if a sufficient web store is present. It is, however, also possible to employ a loop store (18) with a smaller capacity ana to stop the folding turret (11) or a blank unit (12) for producing blanks for a short period.

Abstract: A length of tape is drawn off a reel, passed over the cutting/connecting section of a splicer, passed through a temporary storage vessel and looped back so as to pass over the cutting/connecting section again. Tape clamps hold the two layers of tape on the cutting/connecting section which are then cut. One of the tape clamps is withdrawn while an applicator applies a piece of adhesive tape in a manner which splices a continuous loop of tape. To remove a superfluous portion of the tape from the continuous loop, the loop is moved to a position wherein one end of the superfluous length is located over the cutting/connecting section. The tape is clamped and cut. One of the two tape clamps then lifts the now open end of the loop clear and the superfluous portion is spliced to the tape on a supply reel. The reel is rotated in manner which winds the superfluous length thereonto until the other end of the superfluous length is drawn to the cutting/connecting section.

The extension is cantilevered to the downstream side of the suction box.

Abstract: A method and apparatus is disclosed for forming a zero-speed, butt splice to join together a web from a new roll of material to a web which is from an expiring roll of material and which should be run, at a relatively high speed, through a web processing operation, such as a disposable diaper manufacturing line, under relatively constant, relatively low tension along a predetermined path of travel that includes a running web festoon means having floating dancer rollers and the running web processing operation. To form the butt splice, the leading end of the new web is trimmed by moving one knife wheel assembly along the cutting edge of an anvil. A piece of tape is applied to the leading end so that a portion of the tape projects downstream from that end. The expiring web is held against the anvil and trimmed along the same cutting edge of the anvil. The trailing end of the expiring roll is also simultaneously adhered to the downstream portion of the tape.

Abstract: A tape for splicing the leading end portion of a standby roll of web to the trailing end portion of an active web. The tape includes first and second longitudinally extending sections which are secured to the outer layer and adjacent inner layer, respectively, of the standby roll by adhesive. A longitudinally extending intermediate section which is free of adhesive joins the first and second sections to one another and causes those two sections to coact to hold the outer layer to the adjacent layer during rotation of the standby roll prior to splicing while permitting the outer layer to lift away from the adjacent layer as the splice is made. Longitudinally extending and parallel score lines are formed through the first section but not through the adhesive thereof. The score lines enable two spaced bands of the first section to be peeled away to expose two spaced adhesive stripes for making the splice and to leave an intervening bridge for protecting the stripes against contact with equipment or the like.

Abstract: An apparatus for splicing the trailing end of an unwind depleted web of material to the lead end of a new web of material in a registered and/or abutting mode without the need for any appreciable overlap between the ends of the ceasing or slow-down of the continual forward advance of the web towards a work station, for instance, such as a thermoformer.

Abstract: A web butt splicing device for splicing two successive webs by butting the following end of a first roll of web and the leading end of a second roll of web against each other. In the web splicing device, the following end of the first roll of web is cut and is then drawn to and held on the hold surface of a butt splicing table. The leading end of the second web roll is cut on a provisionally positioning table to the shape of the following end of the first web roll, is then carried to the butt splicing table by a carrying device and is butt spliced to the following end of the first web roll. Therefore, according to the web splicing device, the webs can be butt spliced together without recourse to a manual operation.

Abstract: The disclosed web splicing apparatus and method provide for the in-registry lap splicing of a new web, that has a spaced, regularly repeating pattern thereon to an expiring web that has an identical, spaced, regularly repeating pattern thereon and that is moving under tension and at a relatively high speed along a predetermined path of travel.
