Abstract: A sheet post-processing apparatus that performs a cutting process on a booklet formed by a bundle of center-folded sheets of paper includes: a conveying member that conveys the booklet; a leading edge stopper capable of reciprocating in a booklet conveying direction and used for setting a cutting position by abutting on a center-folded portion of the booklet; and a supporting member that supports the booklet when the cutting position of the booklet is to be set. When the booklet is being conveyed, the conveying member and the conveyed booklet are located in a contact position, and when the cutting position of the booklet is to be set, each of the conveying member and the conveyed booklet is located in one of separated positions, and the cutting position of the booklet is set by the leading edge stopper while the conveyed booklet is supported by the supporting member.

Abstract: A trim press article handling apparatus includes a frame, a punch, a die, and a treadle. The punch is carried by the frame. The die is carried by the frame and cooperates in relative movement with the punch to sever articles from a web. The treadle is carried for movement relative to the die. The treadle includes a web guide member, a primary guide strip spaced from the guide member slightly greater than a thickness of the web, a secondary guide strip spaced from the guide member at least four thicknesses of the web and spaced apart from the primary guide strip, and an article detector carried by at least one of the primary guide strip and the secondary guide strip. The article detector is operative to detect position of an article in the web by detecting the position of a protuberance in the web as the protuberance is conveyed between the primary guide strip and the secondary guide strip. A method is also provided.

Abstract: A roll type stock feed apparatus having one feed roll rotatably mounted on a stationary frame structure, and a second feed roll mounted on a movable roll carrier and yieldably urged into a stock engaging condition. An electro-responsive servomotor is drivingly connected to at least one of the feed rolls for driving the feed rolls through a preselected feed cycle. An elongated ram position sensor is slidably mounted on the stationary frame structure for lengthwise reciprocation along an upright path and is yieldably urged upwardly relative to the frame structure to a preset raised position on the frame structure. A cam on the ram position sensor member engages a cam follower on the movable roll carrier and is operative in response to movement of the sensor member downwardly from the preset raised position to move the roll carrier and the second stock feed roll to a stock release condition.

Abstract: A ledger assembly for a continuous rod cut-off includes a rigid beam (12) carrying ledger tubes (10) and pivotally supported by fibreglass springs (16,22). Vertical springs (22) resist the cutting force of the cut-off knife (30) and allow reciprocal movement of the tubes (10) while imparting a vertical displacement to the beam (12) so that the tubes follow a straight path along the rod line (28). A horizontal spring (16) allows this vertical displacement while providing lateral stiffness for the base of the beam (12). A drive arrangement for the beam (12) includes a lubricating system for a bearing (42) of a connecting rod (36) in which lubricant is collected for return by action of centrifugal force in a housing (72) located on the side of the bearing opposite a lubricant supply path (86, 88) through a crankshaft (40).

Abstract: A stock feed and cutter system for forging machines and the like in which stationary grippers and linearly movable grippers alternately grip rod or wire stock. The movable grippers reciprocate toward and away from the stationary grippers and operate to feed the stock without slippage a precise distance into a cutter. A stock gage is therefore not required and an optimum cutter structure can be provided even for very short workpieces. After each feed operation, the cutter shears a workpiece from the end of the stock, which is subsequently formed to a desired shape. A running adjustment is provided for the reciprocating grippers so that the machine operator can adjust the length of the workpiece produced while the machine is running. A short blank detector independently measures the length of stock being fed and is connected to cause rejection of such short blank. The grippers operate without slippage and, in cooperation with the cutter, produce very uniform workpieces.

Abstract: An improved apparatus for producing and dispensing place mats from a roll of sheet material including curved guide member cooperating with said apparatus to receive said place mats and to curl upwardly the side edge portions thereof permitting said place mat to extend outwardly from said apparatus in cantilever fashion to facilitate handling of said place mat as by positioning it on a tray or the like. When the place mat is removed, the apparatus automatically produces another one extending out of the apparatus for easy handling.

Abstract: Apparatus for subdividing a web of wrapping material into sections of predetermined length has a reciprocable carriage for a pair of grippers which are pivotable into engagement with the web to thereby clamp the web against the carriage while the latter moves forwardly. This advances the web through a distance which approximates but is less than the distance necessary to advance the web by the length of a section. The grippers are thereupon disengaged from the web while the carriage continues to move forwardly, and the web is braked by one or more brushes so that two pawls whose pallets are biased against the web can catch up with a pair of marginal notches in the web. The pallets enter the respective marginal notches and complete the forward movement of the web. A mobile knife cooperates with a stationary knife to sever the web and to thus separate a section from the leader of the web while the carriage moves rearwardly.

Abstract: A device for feeding a workpiece to the saw component of a sawing machine and for clamping the workpiece during the cutting thereof by the saw component, has first and second clamping jaws supported on a table of the sawing machine and cooperating with one another for immobilizing the workpiece; and a feed roller supported at the machine table in the zone of the clamping jaws for feeding the workpiece into the operational range of the saw component. The device further has an arrangement connected to the first clamping jaw for displacing the same towards and away from the second clamping jaw in a direction inclined with respect to the surface of the machine table.
