Patent number: 10407822Abstract: In laundry processing, a conveyor rotates a textile article in a first stage. The article is held while part of the article rests on the conveyor. By conveying while held, the textile article rotates, positioning an edge of the article. In a second stage, the conveyor conveys the article to a clamp. This clamp holds the article while the conveyor reverses direction and a blower attempts to flatten the article if folded. The textile article rotates, positioning the edge of the article to be more parallel with the direction of conveyance. In a third stage, the article is dragged by the edge over a gap where gravity and blowing attempt to flatten the article. In a fourth stage, the flattened article is positioned over a stack. A blower directs air at a center of the article to blow out the corners and assist in maintaining position.Type: GrantFiled: June 2, 2017Date of Patent: September 10, 2019Inventor: Stanley G. McCabe

Publication number: 20140193224Abstract: A separator separates sheets from a bundle. Slack in the strap used to raise and lower a clamp is used to determine when the clamp reaches the bundle. A non-horizontal conveyor tilts beneath the clamp to receive multiple articles, and then tilts over another bin to deposit the articles. The second bin includes an angled surface, which is straightened to shift the articles for clamping. The clamp is supported by, but not attached to, a support connected with the drive. When the clamp reaches the pile, the clamp stops but the support may continue to move. The clamp is tiltable. The article is transferred by an air jet onto a surface with a roller separated from the surface. Upon transfer, the roller forms a nip with the surface. The article is deposited on an exit conveyor having a flexible, raised portion.Type: ApplicationFiled: February 25, 2014Publication date: July 10, 2014Inventor: Stanley G. McCabe

Patent number: 7836617Abstract: A separated article of laundry is dragged over a plurality of wheels or belts. The wheels or belts adjust the amount of overhang on each side, making an edge of the article more horizontal. A clamp clamps the edge and drags the article of laundry from the wheels or belts. Resistance, such as by a pinch arm, may assist in untangling the article of laundry as the article is dragged. Sensors adjacent the belts or wheels measure a size of the article of laundry. A folder adjusts based on the size. For example, the types of folds to be made, the placement of runners for folding, or the output sorting are adjusted. The folder may operate more efficiently by providing time for the folder to adjust to the size of the article of laundry prior to feeding from the spreader.Type: GrantFiled: December 21, 2007Date of Patent: November 23, 2010Inventor: Stanley G.

Patent number: 7827709Abstract: An article is selected and spread from a load of articles. A first clamp moves along a run to remove an article. By changing orientation of the run, articles may be removed from different locations. A second clamp rotates while holding the article. The rotation generally flattens out the article. A third clamp grabs a portion of the article and further spreads the article. This process may detangle or untwist the article. The untwisted article is dragged over a belt. The belt adjusts the amount of overhang on each side. A plate lifts a resulting edge. The article is clamped at that edge and dragged over a roller. The roller moves into contact with a conveyor. The conveyor conveys the article to find a leading edge. The article is then conveyed in a spread position.Type: GrantFiled: June 4, 2007Date of Patent: November 9, 2010Inventor: Stanley G. McCabe

Patent number: 7555857Abstract: Two paths parallel paths feed a common path. A clamp removes separate articles in each parallel path. Each path positions articles on opposite sides of a surface, such as a conveyor. In a back and forth motion, another clamp sequentially clamps the articles of laundry from the opposite sides and places each article on the surface. Another clamp extends through the surface to sequentially clamp the articles on a trailing edge. The clamp moves the articles linearly off the surface and rotates the articles onto another surface, such as a lower surface. On the other surface, the article is conveyed to a pick-up position. A pair of clamps drag the article by an edge onto a stacked position. The stack is adjusted in height to position the stack for receiving the next article.Type: GrantFiled: September 13, 2006Date of Patent: July 7, 2009Inventor: Stanley G. McCabe

Patent number: 7127840Abstract: A towel spreader is provided. A trailing corner is clamped to isolate an edge of a towel where the edge is either along a fold in a towel or along an outer extremity of the towel. The towel is then flattened in a single or two layers using motion and gravity while being held along the identified edge. The same or a different trailing corner is then rotated such that a back outer extremity edge of the towel is perpendicular with a direction of movement of a conveyor. By clamping the back edge while continuing to move a downstream conveyor and blow air on the towel, the towel is flattened out. The spread towel is then passed downstream for further processing, such as folding.Type: GrantFiled: September 17, 2004Date of Patent: October 31, 2006Assignee: FinishTech, Inc.Inventor: Stanley G.

Patent number: 6883258Abstract: Apparatuses and methods spread a towel from a load of towels. The towels are rectangular, such as hand, wash or beach towels. A trailing corner is first identified to isolate one short edge from another short edge. The entire towel is then transported from one side of a center line of a conveyor to another side. Once on the other side, an end of the towel is brought into contact with a moving belt. The moving belt tensions the towel by causing friction downwards or away from the direction the towel is being moved. The clamped corner is moved back to the other side of the center line and released on the conveyor. A pinch belt, such as a pinch belt on one side of the conveyor, conveys one end of the towel in a bunch. The conveyor conveys one portion of the towel while the pinch belt conveys the bunched portion. The conveyor conveys the towel off the end of the conveyor until a trailing corner is detected. A pinch roller is then placed against the conveyor to clamp the trailing corner.Type: GrantFiled: August 6, 2003Date of Patent: April 26, 2005Assignee: Finish Tech., Ltd.Inventor: Stanley G. McCabe

Patent number: 6141893Abstract: A laundry feeder method and apparatus for feeding laundry articles to a spreader apparatus is provided. The feeder allows large king size sheets, as well as other sized laundry articles, to be conveniently readied for spreading by a user. A fixed target is provided on the feeder. The user merely drapes a portion of the laundry article over the fixed target or inserts an edge of the article into a moveable clamp. The moveable clamp then moves along a track to the fixed target for clamping the laundry article. The clamp is then moved away from the fixed target, pulling the laundry article to the spreader, such as the spreader disclosed in U.S. Pat. No. 5,515,627. Multiple fixed targets and associated moveable clamps may be provided to increase the throughput.Type: GrantFiled: June 11, 1999Date of Patent: November 7, 2000Assignee: FinishTech, Ltd.Inventor: Stanley G.

Patent number: 4447972Abstract: A spreader, counter, folder and stacker for laundered articles. The articles are discharged as circulated about an elongated bin. Clips on an endless chain pick the articles up from the bin one by one and elevate them. The clips are released by a cam to drop the articles one by one on traveling catches which pull them for spreading and carry them over a retarded rotation brush. This places a drag on the articles and elongates them for transfer one by one to a spreader bar. A series of spreader bars are provided and each carries the article draped over the bar past the radial tine of a counter. As each article engages a radial tine a drive is energized to a brush conveyor and a counted stack of articles is stacked on the conveyor and discharged from the conveyor to be picked up for use.Type: GrantFiled: December 15, 1981Date of Patent: May 15, 1984Inventor: Stanley G.
