摘要： A dispenser for cutting and feeding a web of flexible sheet material is described in which a feed roller carries a web cutting blade and a spring connected to an eccentric crank affixed to the feed roll. While initial movement of the web through the mechanism and actuation of the cutter to effect partial separation of the web material is produced by the user's pull on the web, such pull also loads the spring which, upon unloading, delivers the cut web material from the dispenser. The spring is designed to gradually arrest rotation of the feed roll and to be exhausted of stored energy at a predetermined position of the feed roll whereupon the uncut segments of web material are efficaciously severed and the leading end of the succeeding web material is automatically positioned where it can be readily grasped by a subsequent user.

摘要： A dispesner for a stack of fan-folded sheet material is disclosed. The dispenser housing has a pivoting brake at the rear wall and contains a major support roller at a height above the rear support rollers to minimize the weight of the stack on the rear support rollers. The major support roller is movably mounted in a pair of vertically-disposed slots and connected at either end to one of a pair of pivot arms. The pivot arms are connected across the width of the dispenser by a connector. The weight of the stack causes the major suport roller to move downwardly in the vertically disposed slots which causes the pivot arms to rotate in the clockwise direction. The clockwise rotation of the pivot arms brings the connector into contact with the pivoting brake which presses against the stack of sheet material in the lateral direction. The lateral pressure on the sheet material decreases the vertical pressure on the bottommost piece of sheet material making it easier for such piece to be removed intact from the dispenser. A piece of friction material may be placed along the inner surface of the front of the dispenser to provide additonal friction on the stack to further decrease the vertical pressure on the bottommost piece of sheet material. An alternative embodiment uses a flat spring in lieu of the pivoting brake, pivot arms and connector. Another alternative embodiment uses two pivoting rollers and a rear brake which forms part of the back wall and is pivotally connected to each side of the dispenser.
摘要翻译：公开了一种风扇折叠片材的叠层分配器。分配器壳体在后壁处具有枢转制动器，并且在后支撑辊上方包含高度支撑辊，以最小化后支撑辊上的堆叠的重量。主支撑辊可移动地安装在一对垂直设置的槽中，并且在任一端连接到一对枢转臂中的一个。枢转臂通过连接器连接在分配器的宽度上。堆叠的重量导致主要的上升辊在垂直设置的槽中向下移动，这导致枢转臂沿顺时针方向旋转。枢转臂的顺时针旋转使得连接器与枢转制动器接触，该枢转制动器在横向方向上挤压片材的堆叠。片材上的侧向压力降低了最下面的片材的垂直压力，使得更容易将这种片从分配器中完整地移除。可以沿着分配器的前部的内表面放置一块摩擦材料，以在叠层上提供额外的摩擦力，以进一步降低最底层的片材上的垂直压力。替代实施例使用平板弹簧来代替枢转制动器，枢转臂和连接器。另一替代实施例使用两个枢转辊和后制动器，该后制动器形成后壁的一部分并且枢转地连接到分配器的每一侧。

摘要： A feed mechanism for feeding a web of rolled flexible sheet material, such as soft paper towels, out of a dispenser. The mechanism includes a feed roller within the dispenser and a web cutting blade in the feed roller and projectable and retractable therewith as the feed roller rotates. A contoured cam is attached to an end of the feed roller, and a spring-loaded cam follower presses against the contoured cam. The cam follower, through the cam, controllably assists in the rotation of the feed roller during the feed roller cycle when the blade cuts the web and thereafter to feed a free end of the material to an accessible position outside of the dispenser. The needed maximum pull forces by the user on the material to cut and withdraw the material from the dispenser are thereby significantly minimized, and the likelihood of the soft towel material tearing off in the user's wet hands is accordingly reduced.

摘要： A dispenser for flexible sheet material having a reserve roll that automatically moves in the dispensing position when the dispensing roll is almost exhausted. The sides of reserve roll guide tracks are angled inwardly to engage the reserve roll spool at an off center point, so the spool is pushed downwardly into contact with a driving roller during rotation. The leading edge of the reserve roll towel engages the remaining portion of the almost exhausted dispensing roll and is moved therewith to be threaded through the dispensing mechanism. The perforating mechanism is assisted through the perforating stroke by a spring mechanism. The sensing roll is halted by a roll stop mechanism including a pivoted stop link and an anti-reverse pawl.

摘要： Dispensing flexible sheet material involves mounting at least one roll on dispensing arm means pivotally connected to a dispenser near the lower end of the chassis so that as material on the roll is depleted the concomitant diminishing diameter roll will swing down on the dispensing arm means for the roll axis to move through an arc spaced from the axis of the feed roller to wedge the roll surface firmly against the surface of the feed roller as the axis of the roll moves toward a line extending through the feed roller axis and the pivotal axis where the dispensing arm means is connected to the chassis. When the roll is essentially depleted it swings past the line and the feed roller into a discard area. Dispensing from multiple rolls in succession utilizes an initial roll mounted as above described and a reserve arm means connected to the chassis through means which permits the reserve arm means to move down vertically relative to the chassis as the initial roll is depleted to a lower position where the reserve arm means thereupon pivots relative to the chassis and the reserve roll engages with the feed roller when the essentially depleted initial roll swings into the discard area to swing through an arc similar to that which the initial roll moved through as the roll diameter diminished.

摘要： A dispenser for flexible sheet material having a reserve roll that automatically moves into the dispensing position when the dispensing roll is almost exhausted. The sides of the reserve roll guide tracks are angled inwardly to engage the reserve roll spool at an off center point, so the spool is motivated to move downwardly toward the dispensing position whenever it is rotated. The leading edge of the reserve roll towel engages the remaining portion of the almost exhausted dispensing roll and is moved therewith to be threaded through the dispensing mechanism. The perforating mechanism is assisted through the perforating stroke by a spring mechanism and is halted by a roll stop mechanism including a pivoted stop link and an anti-reverse pawl.

摘要： A device for rotatably supporting a roll of flexible sheet material having trunnions at the ends is provided with structure forming a friction brake to effectively control overspin of the roll during dispensing of the sheet material. The device involves an end support particularly configured to provide a bearing surface formed of resilient, high friction material effective to engage a portion of an end cap forming a roll trunnion, whereby the braking action provided by the bearing surface is directly proportional to the weight of the roll.

摘要： A dispenser and dispensing method for flexible web material that is wound into a roll on a transversely split core utilizes a housing having opposed parallel guide tracks to guidingly receive roll core supports projecting from the roll ends and a pivoted control lever providing a lever sensing end to detect the presence of an intact roll core in a roll dispensing position and an upper support end to retain a roll in a reserve roll position. The lever has its sensing end biased toward the intact roll core thereby tending to buckle the split core into sections upon exhaustion of web material from the intact roll core whereupon the core sections with their roll core supports are disengaged from the tracks and the reserve rolls is freed from the lever support end to move to the roll dispensing position.
