摘要:
A device for inserting a strip of material in a dispensing machine for material wipes of the type in which the machine includes a housing, a cover, the housing having end shields that support a reel holder, and a drum with a cutting device. The drum includes a cam associated with a start and return spring, a protection flap being located in front of the drum along with a pressure roller resting against the drum. The protection flap has an upper extension forming a support frame devised to accommodate a hinged secondary flap and a swivelling shaped plate is located behind the drum and capable of supporting a service roll that is being used up. The swivelling shaped plate cooperates with a mechanism capable of locking the secondary flap in position when a spare roll (RR) is being loaded and the service roll (RS) is positioned so that it can be used up.

An improved web splicing apparatus that permits better handling of rolls of paper and other materials and the automatic splicing of the beginning of one roll of paper onto the approximate end of a second roll of paper without discontinuing the flow of paper to the utilizing device and without the use of core shafts. The apparatus utilizes two opposed pairs of independently controlled and positioned web roll support arms which are pivoted about spaced shafts and rotatably support cores of the paper rolls. This invention also allows sequential splicing of rolls having unequal web widths. This configuration also allows the right and left roll support arms to move the rolls upward in an overlapping path from a single loading position, thus providing a machine having considerably reduced dimensions and floor-space requirements. Another aspect of this invention is the automatic ejection of depleted roll-cores. A further aspect is the feasibility of configuring a stacked system of multiple splicers by rotating the splicers one quarter of a revolution, allowing machines to be stacked on top of one another to reduce floor space. Yet another aspect of this invention is the ability to remove partially depleted rolls without interrupting the feed of the web. Still another aspect is the use of the motor in conjunction with the brakes to expand the core chucks to grip the inside of the roll cores.

A paper web feeder is provided, which allows easy operations of maintenance and replacement to be achieved on occurrence of a malfunction. In addition, even if the number of wires is increased and connection means is up-sized due to expanded functions of support arms, no influence is given to bearings in support frames for a rotary shaft. A paper web feeder (A) for a rotary press comprises a pair of support frames (16, 17) opposing to each other. A rotary shaft (1) is rotatably supported by the pair of support frames (16, 17). Support arms (3, 4) are provided in plural and radial about the rotary shaft (1) for supporting a paper web (Q1, Q2, Q3) rotatably at each arm tip and configured to rotate integrally with the rotary shaft (1). Rotary conduction means (B) is located at a displaceable angle associated with rotation of the rotary shaft (1) for conducting to an electric device. The electric device displaces in angle associated with rotation of the rotary shaft (1). Stationary conduction means (C) is secured on either of the pair of support frames (16, 17) and conductive to the rotary conduction means (B). Connection means (D) is provided for electrically connecting the rotary conduction means (B) to the stationary conduction means (C). The rotary shaft (1) has axial ends, at least one of the axial ends protruded outside from the pair of support frames (16, 17). The rotary shaft (1) also has a hollow portion (1a, 2a) formed therein extending from a mid-portion between the pair of support frames (16, 17) to the portion protruded outside from the pair of support frames (16, 17). The stationary conduction means (C) and the connection means (D) are provided outside the pair of support frames (16, 17). The rotary conduction means (B) has a portion extended through the hollow portion (1a, 2a) to outside the pair of support frames (16, 17) and electrically connected to the connection means (D).

摘要:
A paper towel dispenser which provides for hands free, automatic feeding of the first sheet of a primary web roll, such as a paper towel roll, into a feed mechanism when its cover is closed. The dispenser also automatically transfers its web feed supply from a primary roll to a reserve roll upon the exhaustion of the primary roll. The present invention eliminates the need for an attendant to thread the leading edge of a primary or reserve roll into the feed mechanism of the dispenser. The dispenser also eliminates wasted paper because it does not begin to feed the reserve roll until the primary roll has expired. The dispenser can include either a manual feed mechanism or a powered feed mechanism. The dispenser relies on a sensor for determining when a portion of the web is absent from a side of the feed mechanism proximate a web discharge opening. When such an absence is sensed, an automatic, powered web transfer mechanism contacts the web located in front of the feed mechanism and positions it between the rollers of the feed mechanism. The transfer mechanism includes a web transfer member and a motor for driving the transfer member in the direction of the feed mechanism. The dispenser also includes a retraction mechanism for returning the transfer bar to a rest position after the web has been introduced into the feed mechanism.
摘要:
A dispenser for dispensing and cutting a measured amount from a web of roll material includes a housing and a roll carrier disposed within the housing to rotationally carry a first web of roll material. A rotatable drum is disposed in the housing proximate to the roll carrier. The roll carrier is biased towards the drum so that a roll carried by the roll carrier is urged towards the drum and the web material is frictionally engaged against the drum to rotate the drum upon a consumer pulling on the free end of the web material. A cutting device extends longitudinally along and is disposed at least partially within the drum. The cutting device extends automatically from a retracted position to a cutting position upon the drum being rotated a constant predetermined amount by a consumer pulling on the free end of the web material. A stub roll carrier is disposed in the housing to rotationally carry a depleted second roll of material that is simultaneously dispensed with the first web of roll material. The stub roll carrier defines an axis of rotation that is behind a vertical plane through the first axis of rotation of the primary roll carrier.
摘要:
In the method in unwinding, paper web (W) is discharged from a reel (R1) that is becoming empty and the paper web of a new full reel (R2) is spliced at the discharge speed to the paper web discharged from the reel that is becoming empty. The terminal end point (L) of the web of the reel (R1) that is becoming empty is stored as information indicating its position in the longitudinal direction of the web in a readable memory (M) corresponding to the reel. During the discharge the distance travelled by the web is determined and compared to the memory, and when there is a predetermined length of web to the terminal end point (L) remaining on the reel (R1) that is becoming empty, a splicing command is given, whereafter the leading end of the paper web of a new full reel (R2) is spliced to the paper web (W) being discharged.

摘要:
A dispenser sequentially dispenses web material from a working web roll and then a reserve web roll. A web sensing mechanism senses the presence of the working web at a back side of the main feed roller and introduces the leading end of the reserve web roll to a feed nip defined by two feed rollers immediately after the trailing end of the working web roll passes over a back side of the feed roller. Web sensing, and controlled introduction of the leading end of the reserve web to the feed nip, are carried out by a simple and effective interaction of a grooved main feed roller, and a pair of pivotable lever arms—a web sensing arm mounted at the backside of the rollers, and a transfer arm mounted at the front side. The mechanism avoids double feeding of web by sensing the presence or absence of web at the back-side of the main feed roller. Transfer fingers of the transfer arm are movable against the reserve roll web and into corresponding grooves in the main feed roller such that a leading end portion of the reserve roll web is reliably moved into the vicinity feed roller nip, where serrations provided in the edges of the grooves facilitate a gripping of the leading end portion to pull the web through the nip. The feed path is arranged to extend away from the transfer fingers so as to avoid interference of the transfer fingers with the subsequent feeding of the web.
