摘要： A system for cleaning a moving substrate includes a rail mounted adjacent to the substrate surface and substantially transverse to the direction of movement thereof. A carriage for supporting a polymer-covered contact cleaning roller (CCR) is deployed on the rail for allowing axial translation of the CCR transversely of the substrate while in rolling contact therewith. The rail extends beyond at least one longitudinal edge of the substrate by a distance at least equal to the length of the CCR such that the CCR may be translated sufficiently to be brought out of contact with the moving substrate surface, from which position the CCR may be readily and safely renewed by an operator or automatically by any convenient means. The CCR mounted on the carriage may be a primary CCR and the substrate may be an object to be cleaned by the system, or the CCR mounted on the carriage may be a secondary CCR and the substrate may be a primary CCR. The extension of the rail beyond the edge of the substrate defines a renewal station for the rail-borne CCR, either primary or secondary, at which the CCR may be renewed automatically or manually by an operator, as by washing, replacement, or removal of a tape convolution. Separation of the renewal station from the CCR-cleaning portion of the rail permits the renewal station, if so desired, to be located outside the primary CCR cleaning area, the rail passing through a light lock, for example, if the substrate must be cleaned in the dark, or an air lock if the substrate must be cleaned in a toxic or otherwise unhealthy atmosphere.

摘要： An apparatus for forming a wound roll of discrete overlapping sheets of web from a supply of continuous web. The web preferably is passed around a nip roller that steers the web onto the surface of a take-up core. A knife assembly including a knife blade extended from a knife holder is driven by a traversing mechanism across the width of the web to cut the wound web on the core into discrete sheets, the extended height of the knife blade being preferably the exact thickness of the web. In transverse cutting by the knife of the web wound on the take-up core, the knife holder travels on the outer surface of the web, thus assuring that the knife blade extends just to the outer surface of the next inner convolution of web, thereby cutting the continuous web into sheets without damaging previously wound web convolutions.

摘要： A system for optimization of a regeneration schedule for a contact cleaning roller (CCR) used to remove particles from a substrate surface by being rolled along the substrate surface. In rolling along the surface, the CCR leaves a residual static charge. The level of leaving charge is sensed by a fieldmeter. When a CCR is first placed into service against a substrate, the leaving charge level is greater than the entering static charge level on the substrate ahead of the CCR. The entering charge is sensed by another fieldmeter, and the charge differential is determined and monitored. As the CCR becomes progressively loaded with particles during service, the leaving charge progressively diminishes. Thus the charge differential indicates inversely the particle loading of the CCR such that a charge differential limit can be set, below which the roller is removed from service and renewed by cleaning.
摘要翻译： 一种用于优化用于通过沿衬底表面滚动从衬底表面去除颗粒的接触式清洁辊（CCR）的再生计划的优化系统。 在沿表面滚动时，CCR留下残留的静电荷。 离地电荷的电平由场仪感测。 当CCR首先投入使用于衬底时，离开电荷水平大于CCR前面的衬底上的进入静电电平。 进入的电荷由另一个场仪测量，并且电荷微分被确定和监测。 由于CCR在服务期间逐渐加载颗粒，所以离开的费用逐渐减少。 因此，电荷微分相反地表示CCR的颗粒负载，使得可以设定电荷微分极限，低于该值时，辊从使用中移除并通过清洁更新。

摘要： A system for cleaning a moving substrate includes a rail mounted adjacent to the substrate surface and substantially transverse to the direction of movement thereof. A carriage for supporting a contact cleaning roller (CCR) is deployed on the rail for allowing axial translation of the CCR transversely of the substrate while in rolling contact therewith. Two renewal stations for cleaning the CCR are mounted adjacent the rail, one outboard of each substrate edge. The CCR is at least twice as long as the width of the substrate and is axially oscillable for a distance sufficient that all portions of the CCR surface may be cleaned by the renewal stations during one oscillation cycle of the CCR while the CCR maintains continuous contact with the substrate across the full width thereof. The CCR mounted on the carriage may be a primary CCR and the substrate may be a continuous web or sheet, or the CCR mounted on the carriage may be a secondary CCR and the substrate may be a primary CCR or other process roller.

摘要： A system for cleaning a web surface including an axially oscillable contact cleaning roller (CCR) positionable to be in contact with the web surface on a free-span of the web. The CCR, which may be mounted in a frame, enjoys a wrap angle greater than 0.degree. and may also be positionable to be out of contact with the web for renewal of the CCR surface. The increased CCR wrap angle can improve the efficiency of particle removal relative to a nipped CCR installation. Either the frame or the roller itself is oscillable such that the CCR may be moved transversely of the web while in rolling contact with the web surface to distribute particles associated with the edges of the web over a broader area of the CCR. Preferably, the ratio of oscillation velocity to web velocity is less than about 0.01 and preferably the web tension is greater than about 0.5 pounds per inch of web width. Plastic and paper webs having a thickness as low as about 0.001 inch may be readily cleaned without wrinkling. Existing CCR web cleaning installations having backing rollers may be readily modified and simplified to provide free-span CCR cleaning in accordance with the present invention.

摘要： A contact cleaning roller (CCR) system includes a shell having an electrostatically active outer surface and being supported by a close-fitting rotatable shaft. The shaft within the shell is provided with a cam groove extending from a first axial location to a second axial location disposed 180.degree. from the first axial location, and then back to the first axial location. A cam follower attached to the inner surface of the shell rides in the cam groove, causing the shell to oscillate axially of the shaft at a frequency of oscillation which is the numerical difference between the rotational frequencies of the shell and shaft. In a preferred embodiment, the CCR shell is nipped against a backing roller, which may be an idle roller or a driven roller, the web passing therebetween in contact with the working surfaces of both rollers. Outboard of the working surfaces, the shaft of the backing roller has a first drive roller having a first diameter, and the shaft of the barrel cam has a second drive roller nipped against the first drive roller and having a second diameter slightly different from the first diameter. Thus, the CCR shell turns at a rotational frequency imposed by the linear velocity of the web whereas the CCR shaft turns at a different frequency as imposed by the relative diameters of the two speed-controlling drive surfaces, the frequency differential being equal to the oscillation frequency of the CCR shell along the barrel cam.

摘要： A system for axially reciprocating a tacky roller (contact cleaning roller, or CCR) across a substrate being cleaned by the roller, to spread particles which are non-uniformly distributed on the substrate surface over a broader area of the tacky roller collecting surface, thereby decreasing the rate of decay of collecting efficiency, improving the average cleanliness of the treated substrate, and extending the operating lifetime of the tacky roller between renewals. The roller may or may not be in contact with the substrate surface during reciprocation of the roller. The system includes a second CCR to alternate with the first CCR, such that at least one roller is cleaning the substrate while another roller is being renewed. The system can be configured to provide full-width CCRs which overlap both edges of a surface at all times during reciprocation. It also can include shorter CCRs for cleaning only a portion of a surface, such as along only one edge, and can also include CCRs substantially shorter than the width of the substrate which can be programmed to reciprocate periodically across the entire substrate width. The system is useful for cleaning workpiece substrates, such as webs and sheets, and also process hardware elements such as calender rollers, coating rollers, conveyance rollers, and other CCRs having surfaces of lower tackiness.

摘要： A web-chopping and sheet-winding apparatus comprising an unwinder for unwinding a supply roll of continuous flexible web which may be adhesive on at least one side. A knife roller including at least one fixed transverse knife blade extending from the surface is in nipped relationship with an anvil roller, the height of the knife blade being greater than the thickness of the web. The anvil and knife roller spacing is such that the knife blade extends just to the surface of the anvil roller, thereby chopping the continuous web into sheets as the anvil and knife rollers turn synchronously with the web passing therebetween. A tape core roller in nipped relationship receives the chopped sheets sequentially, the leading edge of each sheet being lifted from the anvil roller by any of a plurality of novel means.
