摘要： A dispenser and dispensing method for flexible web material that is wound into a roll on a readily deformable hollow core (C) has a housing carrying opposed parallel guide tracks (22-24) to guidingly receive roll core supports (E,F) projecting from the roll ends and a spring biased lever (40) pivoted on such housing, the lever (40) applying an axial force to the hollow core (C) at one roll end and being maintained in a roll retaining condition by the presence, in a roll dispensing position, of a hollow roll core that is held against downward displacement from such position. An axial force (FR) is applied against the other end of the hollow core. The lever (40) serves to retain a reserve roll (R) in a reserve roll position remote from the roll dispensing position with the lever (40) being released from such retaining condition when the web material is exhausted and the hollow core (C) is deformed downwardly, assisted by the axial forces (FR) applied to the hollow core ends, to enable removal of this core (C) from the roll dispensing position whereupon such reserve roll (R) moves to the dispensing position.

摘要： A stop mechanism for a feed roller (22) associated with a cutter (30) in a dispenser (10) for flexible rolled web material (T) has a stop lever (40) mounted to pivot in a plane normal to a feed roller rotational axis, such lever having a slot (44) with lift (46) and stop flanges (48) disposed on opposite sides of the slot, respectively. A feed wheel (36) rotatable with the feed roller has a control tab (38) to successively engage with the lift and stop flanges so that as the feed roller rotates by web material being pulled from the dispenser, the control tab first lifts the stop lever by means of the lift flange and then abuttingly frictionally engages with the stop flange to retain the stop lever in its lifted position and stop feed roller rotation until the frictional engagement is relieved by pulling tension on the web being terminated whereupon the lever drops until the tab can pass over the upper end of the stop flange to free the feed roller for further rotation.

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.

摘要： A dispenser (10) for multiple rolls of web material such as paper toweling that is provided with dispensing mechanism (22) to lead a web of material out of the dispenser (10) to the user has supports (36,38) for rotatably supporting rolls in primary and reserve positions, respectively, with transfer mechanism interactive with such roll supports (36,38) and the dispensing mechanism (22) to automatically transfer web feed from one roll to the other under predetermined sensed conditions. The transfer mechanism includes a pivotally mounted transfer frame (50) swingable to be out of the way to facilitate dispenser loading with the dispenser cabinet cover (14) open, the transfer frame (50) being releasibly retained out of the way in conjunction with dispenser loading, and movable to a sensing location upon closure of the cabinet cover (14) whereat depletion of web material supplied from the roll in the primary position (P) is sensed whereafter the frame again shifts for tucking fingers (70) on the transfer frame (50) to press a web end portion of the reverse roll (R) web material into the dispensing mechanism (22) to thereafter feed web material from such reserve roll (R). A keeper bracket (72) loosely receives this web end portion incident dispenser loading with the action of cabinet cover (14) closing causing the bracket (72) to firmly grip such portion until the transfer mechanism coacts with the dispensing mechanism (22) to thereafter feed web material supplied from the reserve roll (R).

摘要： A dispenser (1) for rolls (14) of flexible sheet material wound on cores is disclosed. The dispenser (1) holds multiple rolls (14) and includes guide tracks (7, 8) for guiding the rolls (14) through the dispenser (1). A holding lever (16) pivotably connected to each side of the dispenser (1) selectively holds the rolls (14) in position in the dispenser (1) and has its pivoting motion controlled by a sensing plate (26) which contacts a lower dispensing roll (14a) to sense when the sheet material is substantially depleted. The lower dispensing roll (14a) is always held out of contact with rollers (50, 52, 54, 56) of a dispensing mechanism (70). A shield (58) is located between the roll surface of the lower dispensing roll (14a) and the rollers (50, 52, 54, 56) of the dispensing mechanism (70).

摘要： Dispensing flexible sheet material involves mounting at least one roll R on dispensing arm means 48 pivotally connected at 54 to a dispenser 12 near the lower end of the chassis so that as material on the roll is depleted the concomitant diminishing diameter roll R will swing down on the dispensing arm means 48 for the roll axis to move through an arc spaced from the axis of the feed roller 24 to wedge the roll surface firmly against the surface of a feed roller as the axis of the roll R moves toward a line extending through the feed roller axis and the pivotal axis where the dispensing arm means 48 is connected to the chassis. When the roll R is essentially depleted it swings past the line and the feed roller 24 into a discard area 60. Dispensing from multiple rolls in succession utilizes an initial roll R mounted as above described and a reserve arm means 66 connected to the chassis through means 76 which permits the reserve arm means 66 to move down vertically relative to the chassis as the initial roll R is depleted to a lower position where the reserve arm means 66 thereupon pivots relative to the chassis and the reserve roll RR engages with the feed roller 24 when the essentially depleted initial roll R swings into the discard area 60 to swing through an arc similar to that which the initial roll R moved through as its diameter diminished.
