Patent number: 7223223Abstract: A method of folding and stacking multiple-sheet sets utilizes a folder having a set feeder that by-passes the folder in-feed station. Sets of multiple sheets are directed directly to the folder processing station, such as a folder station. The set feeder comprises a guide mechanism that guides a set through a cover opening and along a lower guide to the input of the processing station. A sensing device senses the presence of the set and operates the processing station without operating the in-feed station. Alternately, a sensing device is not required, and the folder is operable to process sets using the set feeder by manually assuring that the in-feed station does not simultaneously propel any sheets to the processing station. The folder further comprises a telescoping stacker that holds the number of processed sheets equal to at least the number of sheets loaded at the in-feed station.Type: GrantFiled: June 30, 2006Date of Patent: May 29, 2007Assignee: Bescorp, Inc.Inventor: Timothy D.

Patent number: 6644646Abstract: An inexpensive paper folding machine includes a paper feeder that reliably propels sheets one at a time in a downstream direction. The feeder includes a paper supply station that biases a stack of sheets against a pickoff wheel. The pickoff wheel propels the topmost sheet to a gate tip. The gate tip is comprised of a singulator that is biased against the pickoff wheel. A clearance is set between a singulator screw and the singulator. The clearance is greater than the sheet thickness, but less than two times the sheet thickness. As a sheet is propelled by the pickoff wheel from the paper supply station, the sheet leading edge enters the nip between the pickoff wheel and the singulator. The singulator pivots to take up part of the clearance. If a second sheet is propelled with the topmost sheet, the second sheet cannot pass between the nip. The paper folding machine further comprises a skew compensator that compensates for sheets that are misoriented relative to the downstream direction.Type: GrantFiled: December 3, 2002Date of Patent: November 11, 2003Assignee: Bescorp Inc.Inventors: Timothy D. Lindsay, Chad Bones

Patent number: 6447436Abstract: A combination folder and sealer machine is much more compact than prior separate and individual folder and sealer machines. The combination folder and sealer machine comprises a folder station that grips a folded sheet simultaneously with a sealer station downstream of the folder station. The sheet is thus under complete control as it is propelled from the folder station to the sealer station, thereby eliminating any skewing that might occur between the two stations. Folding rollers at the folder station are biased toward each other, but the sealing rollers at the sealing station are biased away from each other. A single motor drives the folder and sealer stations as well as a feeder station. Drive trains for the sealer and folder stations are on opposite sides of the machine. A bearing mechanism enables any folding roller to be removed from the machine without removing any other roller and without affecting the machine side walls.Type: GrantFiled: May 21, 2001Date of Patent: September 10, 2002Assignee: Bescorp Inc.Inventor: Timothy D.

Patent number: 5968308Abstract: An in-line pressure sealer processes folded sheets with pressure sensitive adhesive into finished business forms. The in-line pressure sealer has pairs of infeed and outfeed rollers, each with a predetermined clearance therebetween. The clearances are adjustably set by means of screws coacting with a frame and with bearing blocks that rotatably mount the rollers. The infeed and outfeed clearances are adjustable independently of each other. The rollers of each pair are biased away from each other to maintain the clearances when no form is present between the rollers. The folded sheets are guided to the infeed rollers by a first cross-piece and to the outfeed rollers by a second cross-piece. A motor, acting through suitable pulleys and belts, drives the infeed and outfeed rollers.Type: GrantFiled: March 2, 1998Date of Patent: October 19, 1999Assignee: Bescorp, Inc.Inventor: Timothy D.
