Patent number: 6773386Abstract: A paper folder including an input drive roller arrangement having an input drive roller with a circumferential gap, and an idler roller forming an input nip with the input drive roller for advancing a paper sheet into a housing; a flexible stripper pad of high friction material positioned at the circumferential gap; a fixed guide which guides the sheet into a loop turning back upon itself such that a leading edge of the sheet impinges upon a transverse line in a trailing portion of the sheet; an output roller arrangement in the housing which forms a folding nip extending along and adjacent to the transverse line; a second drive arrangement in the housing in front of the transverse line for positively driving the leading edge to impinge upon the transverse line; and a stocker mounted on the housing for stocking a plurality of fully folded paper-like sheets.Type: GrantFiled: May 14, 2003Date of Patent: August 10, 2004Assignee: Shap Inc.Inventor: Tadeusz Staniszewski

Patent number: 6000875Abstract: For mounting a machine element having a bore coaxially on a shaft for rotation with the shaft, there are provided a first member having internal threads, and a split sleeve having external threads adapted to be mounted around the shaft and inside the bore. The threads of the split sleeve have apexes at a uniform diameter when unstressed. The first member is threaded on the external threads of the split sleeve. Also, a second member is spaced from the first member by an amount sufficient to allow the first and second members to embrace opposite sides of the machine element. The threads of the first member and the split sleeve are shaped to cause contraction of the sleeve into fast, gripping engagement with the shaft, as the first and second members frictionally clamp the machine element between these first and second members.Type: GrantFiled: January 22, 1996Date of Patent: December 14, 1999Assignee: Shap, Inc.Inventor: Tadeusz Staniszewski

Patent number: 5770005Abstract: A housing confines therewithin a saturated sponge, the same disposed for moistening the flap of an envelope. Too, the housing has a entry slot for an envelope, and a switch, with an operating sensor or limb which detects the entry of an envelope into the housing, for the purpose of rotating rollers which (a) move the envelope from the entry slot to an exit, and (b) cause the flap to wipe across the sponge and seal against the body of the envelope.Type: GrantFiled: November 12, 1996Date of Patent: June 23, 1998Assignee: Shap, Inc.Inventor: Tadeusz Staniszewski

Patent number: 5683045Abstract: Paired, coacting, albeit non-contacting rollers have interfitting collars or rings, and tapered rims, which are rotatably driven in opposite directions. Paper fed therebetween is torn asunder, and freely discharged therefrom. The rings cooperate together to force the paper to be torn lengthwise thereof, and the rims crease the resulting strips to insure that they do not remain lodged between the rings. An embodiment has helical rings or collars which cause the paper to be dismembered into diagonally-shaped, fine fragments.Type: GrantFiled: March 27, 1995Date of Patent: November 4, 1997Assignee: Shap, Inc.Inventor: Tadeusz Staniszewski

Patent number: 5487718Abstract: A housing, having therein only one, driven, rotatable drum, receives sheet paper for in-folding or Z-folding, selectively. Abutments, within the housing, delimit travel of the leading edge of the paper, causing the paper to buckle, there behind, and form a nip or fold; the latter is directed between the drum and a guide to one of the abutments, causing the paper to fold again. Then the fully folded paper is discharged from the housing. One of the abutments is retractable, to accommodate a Z-fold, or extendable to enable an in-fold.Type: GrantFiled: February 25, 1994Date of Patent: January 30, 1996Assignee: Shap, Inc.Inventor: Tadeusz Staniszewski

Patent number: 5466327Abstract: A flexible leaf causes the gummed flap of an envelope to enter a chamber in which a moistening element is exposed. In addition, a pivoted and spring-biased element yields upon engagement of the envelope spine therewith. Further movement of the envelope wipes the flap across the moistening element, and the spring-biased element presses the moistened flap against the body of the envelope.Type: GrantFiled: October 14, 1994Date of Patent: November 14, 1995Assignee: Shap, Inc.Inventor: Tadeusz Staniszewski

Patent number: 5067846Abstract: A mounting device can mount a machine element having a bore coaxially on a shaft. The mounting device has a first member having internal threads. Also, included is a split sleeve having external threads adapted to be mounted around the shaft and inside the bore. The threads of the split sleeve have apexes at a uniform diameter when unstressed. The first member is threaded on the external threads of the split sleeve. The mounting device also has a second member spaced from the first member by an amount sufficient to allow the first and second members to embrance the machine element. The threads of the first member and split sleeve are shaped to cause compression of the sleeve as the first and second members embrace the machine element.Type: GrantFiled: September 4, 1990Date of Patent: November 26, 1991Assignee: Shap Inc.Inventor: Tadeusz Staniszewski

Patent number: 4016822Abstract: An attachment for sewing machines for folding and pressing seam plies for sleeves, trousers and the like having a pair of endless belts or tapes between which the cloth being sewn is carried. After the seam has been sewn, the cloth is carried forwardly into the path of a V-shaped seam opening member which causes the seam plies to be separated, be positioned at right angle to the cloth and lie on either side of the seam in a common plane. Upon being carried further forwardly, the seam plies engages a seam folding member which guides and folds over the seam plies from their right angle position to a flattened position against the cloth whereby the seam plies lie in substantially the same plane as the two layers of cloth after which the heated rollers and a hot air blower presses the four layers of cloth in superimposed contact relation.Type: GrantFiled: November 20, 1975Date of Patent: April 12, 1977Assignee: Shap, Inc.Inventor: Antonio Pugliese
