ABSTRACT:
Disclosed is a tape tightening mechanism for an automatic packer including a conventionally structured tension arm and a rail having an upper end pivotally connected to a top rear end of the tension arm and a lower end leading to an upper end of a tape-feeding channel, so that a tape for packing can be fed from the tape-feeding channel to a tape-operating unit of the packer via the rail and the tension arm. A vertical section extends downward from the lower end of the rail and forms a stop wall to a top rear side of the tape-feeding channel. When the tension arm is swung backward to tighten the tape around a package, the rail connected thereto is pushed to move backward, causing the vertical section to separate from the top rear end of the tape-feeding channel to provide a widened path between them for the tape to pass therethrough and enter the rail without becoming bent. When the tension arm is in a tape tightening position, a part of the tape is pushed back into a tape storage, and when the tension arm returns to its original position, the tape can be pulled out from the storage again for packing.
