Patent number: 5346150Abstract: The tail gap winder transfers a web from a first wind-up spindle to a second wind-up spindle by, immediately after the web is cut, pivoting the idler roller to lengthen the distance between the idler roller and the rotating drum to create a gap between the cut ends of the web; moving the first wind-up spindle away from the rotating drum surface as the gap passes under the first wind-up spindle location; moving the second wind-up spindle into contact with the rotating drum surface as the first wind-up spindle moves away; and winding the incoming cut edge around the second wind-up spindle. The idler roller pivots toward the rotating drum to decrease the distance between the idler roller and rotating drum and to take up the extra length of web during the winding portion of the operating cycle.Type: GrantFiled: March 26, 1993Date of Patent: September 13, 1994Assignee: Minnesota Mining and Manufacturing CompanyInventor: Leonard M.

Patent number: 5339570Abstract: The contact wheel according to the present invention comprises an annular support portion having external surfaces, and a generally cylindrical peripheral surface. The peripheral surface has spaced edges each adjoining an adjacent external surface, and circumferentially spaced elongate grooves formed therein with land portions disposed between the grooves. The grooves are spaced from the respective adjacent edges of the peripheral surface to provide annular land surfaces at each edge of the peripheral surface. The contact wheel further includes one or more passageways formed therein, which communicate with a groove at a first end of the passageway, and with either an external surface of the annular support portion, or an adjacent groove at a second end of the passageway. The passageways aid in reducing the amount of noise generated by the contact wheel when it is rotated with the abrasive belt entrained thereover.Type: GrantFiled: August 17, 1992Date of Patent: August 23, 1994Assignee: Minnesota Mining and Manufacturing CompanyInventors: Steven E.

Patent number: 5226281Abstract: A z-tab innerseal for a container and method of application involves an innerseal having a first sealing portion for sealing a first portion of an opening defined by an upper rim of a container, a second sealing portion for sealing the remainder of the container opening and a flap portion between the first and second sealing portions which is adapted to be grasped and pulled upwardly by a user to remove the innerseal from the container opening. An advantage of the flap portion is that it allows the innerseal to be removed without having to penetrate or scrape the innerseal with a sharp object such as a knife. A method of forming the improved innerseal includes providing a blank of stock material having a folded portion, cutting the blank to form an innerseal, mounting the innerseal onto the rim of a container and sealing the innerseal to the container by passing the assembly through a heating station.Type: GrantFiled: December 17, 1991Date of Patent: July 13, 1993Assignee: Minnesota Mining and Manufacturing CompanyInventors: Hak-Rhim Han, Theresa A.
