<p>1,266,849. Dispensing tape. SIGNODE CORP. Nov.2, 1970 [Nov.3, 1969], No.52015/70. Heading A4G. A dispensing mechanism for strap comprises a frame 18, an arm 16, pivotally mounted (at 72) on the frame, a reel 10 to support a coil of strap material, means on the arm spaced from the arm pivot supporting the reel for rotary movement, strap guide means 84 on the arm spaced from the arm pivot and defining a reaction member about which a length of strap unwound from the reel may be trained, and brake means 50, 52 on the frame for frictionally engaging the reel to brake rotational movement, the arrangement being such that a pull on the unwound length of strap will cause the arm to pivot, moving the reel away from engagement with the brake means to allow the reel to rotate and as the pull on the unwound strap is decreased, the arm will pivot to bring the reel into engagement with the brake means. Guide means may be a roller, as shown. Stops 68, 58 may be provided to limit the movement of the arm. The reel axle may be carried in notch formed by sides 94, 96 and 98, and projection 102 may extend over the notch to prevent the reel slipping out when the arm is tilted.</p> |
