Title: Film feed mechanism for a wrapping machine
IPC: B65B41/16
Filed: 1970-03-12
Abstract: 1,272,736. Wrapping machines/film feeding. J. B. DOVE Inc. 12 March, 1970 [3 April, 1969], No. 11820/70. Headings B8C and B8R. In a wrapping machine comprising a wrapping mechanism 14, 15 which pulls film 20 thereto from a loop of film trained about a tensioning roller 67 situated between a roller 68 and a stripper roller 66, the tensioning roller 67 is carried by a pair of pivoted spring biased arms 91 which pivot as the loop is depleted to cause a continuously driven chain 88 to engage a sprocket (86, Figs. 5, 6, not shown) and rotate the stripper roller 66 to withdraw film from a roll 29a and replenish the loop. The arms 19 are connected to a track arm 101 which carries a roller 103 abutting the lower end of a track link 122, the upper end of which is secured to a plate 111 which is pivotally mounted at 112 and which carries a chain guide assembly 106. When the loop is full the arms 91 cause the guide assembly 106 to hold the chain 88 clear of the sprocket (86). When the loop is depleted the arms 91 cause the chain guide assembly 106 to fall and allow the chain 88 to drop and engage the sprocket (86). The machine carries three rolls 29a, 30a, 31a of film mounted on repsective arbors 29, 30, 31 and selectively connectible to the stripper roller 66. Each arbor is equipped with an adjustable braking belt 33 to adjust the speed of rotation thereof. The stripper roller 66 has strips 83 of silicone sponge to assist friction gripping of the film. Each arbor 29 comprises a tube (40, Fig. 6) rotatably cantilevered to a fixed plate 26, and a roll of film is held on the tube by a pivoted shoe (47) which is pivotable through a slot (62) on the tube to engage the roll. The shoe (49) is pivoted by means of a rotary knob (54) at the free end of the tube. The wrapping mechanism comprises vertically movable elevators 14a, 14b, a dancer roller 15, and a draper roller 15a. In operation a conveyer 16 feeds an article on to the elevator 14b and relative movements of the elevators 14a, 14b and the dancer roller 15 result in the article being transferred to the elevator 14a and having a section of film folded therearound. The partially wrapped article is transferred to a table 17a which is part of an end folding and sealing mechanism 17.

Abstract: 1,263,223. Fluid pressure brakes. BENDIX CORP. 18 March, 1970 [24 March, 1969], No. 12907/70. Heading F2F.  A vehicle hydraulic braking system comprises a vacuum suspended servomotor 10 and a master cylinder 14, the servomotor including a movable wall 28 between chambers 30, 32, a control valve 66 carried in a hub portion of the wall 28 and operable by a push-rod 64 for controlling a fluidpressure differential across the wall 28 and a force transmitting member 54 in the form of three concentric pistons 58, 60, 62 for transmitting, through the intermediary of an hydraulic fluid chamber 110, the force generated by the movable wall and the operator to the master cylinder piston 112, the effective area of member 54 exerting pressure on the fluid being varied as power run-out or failure occurs. Pressure on a brake pedal 12 to move rod 64 causes valve 66 to cut off chamber 30 from chamber 32 and allow atmospheric air to flow into the latter and move the wall 28 and thus member 54, the pistons 58, 60, 62 acting as a single piston until at the point of vacuum runout piston 58 secured to the wall ceases to move. Additional pedal effort causes movement of piston 62 until a flange 98 abuts piston 60 and causes it to move in unison with piston 60, the action of the two pistons instead of three producing a larger effective force. Power failure results in a similar effect. Piston 62 also includes a valve member 108 which can engage a valve seat 114 in piston 112 on initial movement of the piston 62.
