Patent number: 6579364Abstract: Sheet products, such as card stock, envelopes and other paper products (10) are advanced on a vacuum surface conveyor belt (30) beneath a glue applicator drum (35). The glue transfer strips (37 and 38) of the glue applicator drum apply stripes of glue (42 and 43) at the ends of the sheet product, leaving a belt engaging space (41) without glue between the glue stripes. The sheet product is grasped by overlying conveyor belts (46 and 47) at the belt engaging space (41), thereby exposing the wet glue stripes on opposite sides of the belts. Hot air is applied on opposite sides of the conveyor belts (46 and 47), drying the glue. The glue transfer strips (37 and 38) of the glue applicator drum can be adjusted in size, shape and position so as to apply glue to one end, the other end, or both ends of the sheet product, and if glue is applied to only one end, one of the dryers (50 or 51) can be deactivated, saving energy.Type: GrantFiled: March 22, 2002Date of Patent: June 17, 2003Assignee: VerMehren Engineering Corp.Inventor: H.

Patent number: 6164438Abstract: An adjustable control roller apparatus for use in a belt-type conveyor assembly comprises a upright support arm having a pivot pin and a first attachment member, and a pivot member engaging the pivot pin. The pivot member has a second attachment member and a pair of rollers rotatably mounted thereon. A biasing member engages the first and second attachment members for biasing the rollers of the pivot member toward the lower conveyor belt of a second section of the conveyor assembly. A support bracket is also included for adjustably supporting the upright support arm so that the rollers can be positioned between the exit pulleys of a first conveyor section and the entrance pulleys of the second conveyor section of the conveyor assembly.Type: GrantFiled: June 9, 1998Date of Patent: December 26, 2000Inventor: H.

Patent number: 6105637Abstract: A fill hopper assembly (30) includes two fill hoppers (50) and (52) which are reciprocated back and forth beneath a feed hopper (14) and over discharge openings (72 and 74) of a discharge bridge plate (32). The upper fill hopper bridge plate (34) includes an intermediate bridge (48) that closes the hopper extension (28) when the fill hopper assembly is in transition to place one of its fill openings (36 or 38) beneath the feed hopper extension (28). The fill hopper bridge (48) closes the fill hopper extension until one of the fill openings (36 or 38) is in registration with the extension (28). Likewise, the discharge bridge plate (32) includes a bridge (76) that closes the bottom openings of the open-ended fill hoppers (50 and 52) when the fill hoppers are centered and as they approach their laterally displaced discharge openings (72 or 74).Type: GrantFiled: March 31, 1999Date of Patent: August 22, 2000Inventor: H.

Patent number: 5962078Abstract: A gummer roll apparatus preferably for applying gum to envelopes during continuous processing and operation of a gumming machine, has a pick-up roll, a meter roll and a transfer roll that transfers a gum or adhesive such as latex to a gummer roll. The pick-up roll and meter roll rotate in opposite directions and are in a skidding-like contact due to different rotational speeds whereby excess gum or adhesive is removed from the pick-up roll and returned to a gum box or trough with a minimum of foaming in the gum box and on the pick up roll.Type: GrantFiled: June 7, 1995Date of Patent: October 5, 1999Inventor: H. Richard VerMehren

Patent number: 5753041Abstract: A gumming roll preferably for use with apparatus for applying gum to blanks and pertains has gear driven rollers and the rollers are in skidding contact for returning excess adhesive to an adhesive pan without substantial foaming of the adhesive. The gumming apparatus speed of operation is greater than the conventional apparatus in which adhesive foaming is a problem.Type: GrantFiled: June 7, 1995Date of Patent: May 19, 1998Inventor: H. Richard VerMehren

Patent number: 5752367Abstract: An apparatus (5) for packaging generally granular materials is disclosed. The apparatus includes a structural framework (7) on which a feed hopper (8) is mounted, the feed hopper being supplied with the material to be packaged, and storing the material therein. A fill hopper assembly (11) is supported on the framework with respect to the feed hopper, and has a spaced pair of fill hoppers (31, 32) received thereon. As spaced pair of discharge chutes (15, 16) are also supported on the framework, and are offset with respect to the feed hopper. Each one of the fill hoppers is alternately moved into alignment with the feed hopper and into alignment with one of the discharge chutes, respectively, in reciprocable fashion on the framework.Type: GrantFiled: November 6, 1996Date of Patent: May 19, 1998Inventor: H. Richard VerMehren

Patent number: 4624408Abstract: Envelopes and letter sheets are mounted on a continuous carrier in such a manner that they alternate and are continuously shingled. The envelope flaps are first affixed to the carrier sheet, with the envelopes in an open position and with their flap folds adjacent and parallel to infolds between carrier sheet panels. The letter sheets are then affixed to the same panels, with the free end of each sheet extending across both an outfold and the next infold. When the carrier sheet is fanfolded, each envelope closes over the top margin of the following letter sheet, and the lower margin of each letter sheet extends across the upper margin of the following envelope.Type: GrantFiled: February 14, 1985Date of Patent: November 25, 1986Inventor: H.
