Title: Mechanism for applying tear strips to wrappings
IPC: B31B50/00
Filed: 1958-10-29
Abstract: 849,400. Cutting-apparatus. HESSER, MASCHINENFABRIK A.G., F. Oct. 29, 1958 [Nov. 19, 1957], No. 34677/58. Class 31 (1). [Also in Groups XV and XVII] Relates to mechanism for applying a tearstrip A, Fig. 3, to a wrapper E so as to extend beyond one edge thereof. Wrapping web E, Fig. 1, is fed between guide-plates 3, 4 and tearstrip stock A is fed below a longitudinal slot 3<SP>1</SP> in the plate 3. A knife element 8 with cutting- edges 14, 15 spaced longitudinally by an amount corresponding to the length of tear-strip required to extend beyond the edge of the wrapper, is reciprocable transversely to the slot 3<SP>1</SP> and in its operative position is located between the web E and tear-strip A. The cutting-edge 15 co-operates with a knife 9 to make an incision in the web E corresponding to the width of the tear-strip and at the line of eventual separation of the web, while the cutting-edge 14 co-operates with a knife 10 to sever the tear-strip. The knife 10 is carried in a recess in a heated presserbar 13 which reciprocates vertically to engage in the slot 3<SP>1</SP> of the guide-plate 3 and cement the separated parts of the tear-strip to the wrapping web immediately following the cutting- operation. The recess in the bar 13 prevents the cementation of the web and the portion of the tear-strip which will eventually extend beyond the edge of the separated wrapper. A further length of wrapping web and tear-strip is then drawn forwards and the operation repeated, the web on each side of the tear-strip then being severed at the line where the incision was made to form the individual wrappers with tear-strip applied as shown in Fig. 3.

With the pistons in the positions shown in Fig. 1, lubricant supplied through conduit 26 causes the pistons to descend and eject lubricant to points requiring lubrication through conduits 46 and 48. Lubricant under pressure then passes through conduits 17 and 20 to operate on a piston 107 and thereby effect movement of the change-over valve 22. Lubricant under pressure is then supplied through conduit 27 to effect upward movements of the pistons and discharge of lubricant through conduits 45 and 47. From the cylinder 5, lubricant under pressure passes through conduits 18, 21 to operate on the piston 107 and effect the return movement of the change-over valve 22. Lubricant displaced by the piston 107 is discharged to lubrication points through conduits 47a and 48a. In order to avoid excessive pressure drop in the oil if too large a number of cylinders is connected in series, two such distributing units may be connected in parallel. The right-hand wall of each unit incorporates additional flow passages and non-return valves. Specification. 888,142 is referred to.

Abstract: 1280641 Hydrostatic transmission JOSEPH LUCAS (INDUSTRIES) Ltd 24 Oct 1969 [25 July 1968] 35479/68 Headings F2C and F2D The control of an hydrostatic transmission comprising a piston-type pump 1 and a motor 3 having their cylinder rotors 8 communicating through a common ported member 10, is effected by a servo 14, 15 acting to pivot the member 10 through a rack 13 engaging teeth 12 on the member, the servo fluid pressure being varied in accordance with engine speed and vehicle throttle position. The servo pressure in line 25 is provided by an engine-driven pump 33 and is controlled by a manually positioned valve 22. In all three forward positions of the valve, line 25 is connected to a line 18 on one side of the piston, and in reverse position of the valve, line 25 is connected by a line 19 to the other side of the piston. The valve is positioned through linkwork 27-29 and limits the maximum speed attained in forward in its two intermediate positions 1 and 2. Link 29 abuts a cam surface 32 on a member 10, (or alternatively on the rack 13), so that as the member 10 turns, the valve 22 is withdrawn at predetermined points in the 1 or 2 forward positions to interconnect lines 18 and 19 to stop servo piston 14. The pump 33 delivers fluid via line 44 to one side of a piston 46 integral with a piston 47 in a communicating cylinder. Line 25 is connected to the opposite side of the piston 46, and the two sides communicate through a restricted orifice 52 between two lines 53, 54 also communicating with opposite sides. The two lines are also variably connected through a valve 62 positioned by a linkage 63 connected in the engine throttle control linkage 64-66. Pivoting of link 63 about a fixed point 73 is limited at low ratios and in neutral by engagement in a slot 67 in a rod 68 abutting a cam surface 71 on the member 10. The rod 68 is also connected at its other end by levers 76, 77 to limit pump displacement in high ratios. A valve 79 vents line 54, and is loaded by a spring 83 acting through a lever 91 having a pivot point 92 determined by the position of a manual control 64 having a lost motion connection with the throttle linkage. Opening of valve 79 also directs fluid in line 54 to the end of a piston 85 connected to the throttle linkage to close the throttle.
