<p>A readily tearable packaging tape provided. The packaging tape comprises an elongate main body portion of substantially constant cross section having a generally centrally disposed longitudinal axis, a thickness defined by a top surface and a bottom surface, a width defined by a pair of side edges, and a length defined by a first end and a second end, and with a coating of adhesive applied to the bottom surface. There are a plurality of tear-inducing cuts formed in the main body portion disposed along the length thereof, such that the packaging tape exhibits the characteristic of ready tearibility at the tear-inducing cuts so as to cause those cuts to develop into elongate tears in the tape, and so as to thereby ultimately cause the tape to separate into at least two portions. The main body portion of the packaging tape exhibits the characteristic of being resistant to tearing, other than in the region of the elongate tears. There is also provided a mechanism for effecting the tear-inducing cuts in the packaging tape, including an axle member, a pair of tape guide members to receive a portion of the non-adhesive side of said packaging tape, a support surface for the tape, and a tape cutting member mounted on the axle for rotational movement and having at least one tape cutting portion extending beyond the support surface. The tape cutting portion is shaped and dimensioned to effect the tear-inducing cuts in the packaging tape by intermittently engaging and making the tear-inducing cuts in the packaging tape as the packaging tape is drawn lengthwise across the support surface.</p> |
