Title: Machine to form box parts
Inventor: LEEPER ALAN L
IPC: B31B3/52
Filed: 1987-03-30
Abstract: A machine to form and end of a unit of a box from a flat box blank (50) that includes two sides (50A, 50B), a bottom, (50C) and, at each end, an end flap (50D, 50D') supporting a cantilevered sealing tab (50E, 50E') and two side tabs (50F, 50F'; 50G, 50G') supported by the two sides. A planarfolding table (57) receives the end flap (50D, 50D') and the sealing tab (50E, 50E'). A pair of side guides (48A, 48B) secures the two sides (50A, 50B) of the box blank (50) and guide the box blank in its rearward travel. An end flap folding mechanism (61A, 61 B) serves to fold the two side tabs (50F, 50F'; 50G, 50G') attached to the box sides (50A, 50B) inward through ninety degrees to a position essentially parallel to the fold line (50H, 50H'). An adhesive applicator (58, 59) applies an adhesive ribbon in a predetermined pattern to the sealing tab (50E, 50E') and, sometimes, to the end flap (50D, 50D'). A drive mechanism (15A) folds the folding table (57) from a position in which the plane of the folding table (57) is in the plane of the movable table (51) to a position in which the plane of the folding table (57) is perpendicular to the plane of the movable table (51) to fold the end flat (50D, 50D') through ninety degrees. A finger assembly (70) consisting of a plurality of press fingers (70A-71AI) is disposed above and separated from the movable table (51). The press fingers (70A-701) have a planar bottom face (70') and a planar back (70"). The press fingers operate in pairs and are movable transversely to a position where the fingers of a pair are spaced from one another to another position wherein the press fingers of a pair are in close proximity to one another. Some of the finger assembly can be moved selectively transversely to accommodate various box widths.

Abstract: A control circuit (20) having a slow-start section (29) is enabled to carry out its expected, principal function(2) only after the voltage at the slow-start section input has reached a certain level. The system assures that a delay interval in control circuit operation is measured from the time that devices (212,213) within the circuit's internal voltage supply (22) become effective to deliver voltage levels sufficient to allow the circuit (20) to perform the principal function. A delay network (50A) is connected across a device (212) of the internal voltage supply (22), which otherwise supplies an operating voltage level to the control circuit (20).

Abstract: The cycle includes water-injection, steam-­injection, recuperation (or regeneration) and waste-heat boiler heat recovery in an arrangement that provides high thermal efficiency, flexible operation in a cogeneration plant and favorable capital cost in relation to thermodynamic performance when compared to currently practiced cycles. In the present cycle, the sensible enthalpy of the exhaust gases between turbine exit and stack is used to simultaneously and in-parallel heat both air and water/steam. A smaller amount of water is boiled than in the known Cheng cycle, in which the exhaust heat is used only to heat water/steam. Thus, the latent heat exhausted at the stack in the present cycle is lower than that for the Cheng cycle resulting in higher efficiency.

Abstract: A nonwoven web is formed by feeding separate supplies of fibrous material into contact with two separate lickerins that are parallel to each other and rotated toward each other. The fibers from the two lickerins pass through a mixing zone and are accumulated on a moving conveying screen that is moved parallel to the axes of the lickerins. A baffle plate may be inserted into the mixing zone and acts to control the lateral or cross sectional composition of a web formed by the fibers accumulated on the screen. When different fibrous materials are fed to the lickerin along their length, the vertical composition of the web is altered.

Abstract: The invention relates to a single nozzle injection molding system in which the nozzle (10) is reciprocated longitudinally to valve gate the flow of melt to the cavity (24). The nozzle has a pointed tip (20) which seats in the gate (22) in the forward closed position and is retracted to the open position. The nozzle (10) is secured against rotation, and an inner collar (6 is secured to it. This inner collar (6 threadably engages a surrounding outer collar () which is free to rotate, but secured longitudinally. A pneumatic piston (9 is connected to the outer collar () to rotate it through a predetermined angle. Thus, when the outer collar () is rotated in one direction, the inner collar (6 and nozzle (10) are driven to the forward closed position, and when the outer collar () is rotated in the opposite direction the inner collar (6 and nozzle (10) are retracted to the open position.
