Abstract

A manually operated taping device has a drawback mechanism to draw back the landing end of the tape immediately after the tape is cut and tape tension removed by extending a tape path between the tape source from which the tape is dispensed and an applicator for applying the tape and/or by minimizing the spacing between the applicator and the cutting knife used to cut the tape at the time the tape is cut. The device may also include a guide to better ensure the device is moved during tape application in the direction relative movement between the tape and device.

Claims

1. A manually operated device for applying tape comprising a frame, a tape source of tape having an adhesive side and a non-adhesive side to be applied by said device mounted on said frame on a tape mounting, a handle extending from said frame, a tape path extending from said tape source to an applicator for applying a leading end of said tape, said applicator pivotably mounted on said frame for rotation about a pivotal axis, said applicator including an application wiper for applying said tape, a spring biasing said applicator from a retracted position toward an initial position where said application wiper is in a position for said applying of said leading end of said tape, an arm, an actuating wiper and a cut off blade mounted on said arm, said arm being mounted on said frame for rotation on a rotational axis located on a side of said pivotal axis remote from said tape source, and actuating wiper and said cut off blade extending beyond said arm in non-parallel directions on opposite sides of said rotational axis and said cut off blade being closer to said applicator than said activating wiper, so that movement of said actuating wiper pivots said arm about said rotation axis which moves said cut off blade across said tape between a retracted position and a cutting position to cut said tape, a first cam connected to and movable with said applicator, a cooperating cam connected to said arm, said first and said cooperating cams cooperating to prevent movement of said applicator until movement of said arm frees said applicator via said first and said cooperating cams.
