Abstract
Abstract Apparatus for handling a multi-layer tape in a postage meter printing machine wherein a portion of the tape is printed with indicia and advanced to the operator and a protective backing portion is wound up on a motor-driven reel after being separated from the printed portion. Advancement of the backing portion of the tape by the reel advances the separated printed portion to the operator. Prior to being wound on the reel, the backing portion of the tape is guided around two sets of rollers defining three points of tangency with a star wheel having radial projections in registration with slots formed in the edge of the backing portion of the tape. Advancement of the backing portion of the tape rotates the star wheel, which includes a plurality of pins which cooperate with a switch to deactuate the motor of the wind-up reel after the star wheel has rotated through a predetermined arc. Deactuation of the means for advancing the tape after the star wheel has rotated through a predetermined arc assures that a precise unit of the printed portion of the tape is presented to the operator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
In an apparatus for advancing a multi-layered tape having a plurality of spaced perforations along an edge thereof through a predetermined distance said apparatus being of the type wherein said tape is advanced along a support means by a drive means, and a control means initiates the operation of said drive means to advance said tape and deactivates the operation of said drive means after said tape has advanced through a predetermined distance, and wherein said control means includes a rotatable wheel having radial projections disposed at spaced intervals around its circumference to engage the spaced perforations along the edge of the tape as the tape is advanced, wherein the improvement comprises guide means adjacent to the circumference of said wheel for maintaining said tape in a finite series of at least two substantially tangential relationships to the circumference of said wheel in the path of rotation of said radial projections, each of said tangential relationships in said series being separated from any other by a portion of said tape strip not in tangential relationship with said wheel, whereby as said tape is advanced said wheel is rotated by the perforations in said tape engaging said projections on said wheel.
Claim 2
Dependent Claim
200 words
In an apparatus for advancing a multi-layered tape having a plurality of spaced perforations along an edge thereof through a predetermined distance said apparatus being of the type wherein said tape is advanced along a support means by a drive means, and a control means initiates the operation of said drive means to advance said tape and deactivates the operation of said drive means after said tape has advanced through a predetermined distance, and wherein said control means includes a rotatable wheel having radial projections disposed at spaced intervals around its circumference to engage the spaced perforations along the edge of the tape as the tape is advanced, wherein the improvement comprises guide means adjacent to the circumference of said wheel for maintaining said tape in a finite series of at least two substantially tangential relationships to the circumference of said wheel in the path of rotation of said radial projections, each of said tangential relationships in said series being separated from any other by a portion of said tape strip not in tangential relationship with said wheel, whereby as said tape is advanced said wheel is rotated by the perforations in said tape engaging said projections on said wheel.
Claim 3
Dependent Claim
15 words
The improved apparatus of claim 1 wherein said guide means comprises a plurality of rollers.
Claim 4
Dependent Claim
202 words
In an apparatus for advancing a multi-layered tape having a plurality of spaced perforations along an edge thereof through a predetermined distance said apparatus being of the type wherein said tape is advanced along a support means by a drive means, and a control means initiates the operation of said drive means to advance said tape and deactivates the operation of said drive means after said tape has advanced through a predetermined distance, and wherein said control means includes a rotatable wheel having radial projections disposed at spaced intervals around its circumference to engage the spaced perforations along the edge of the tape as the tape is advanced, wherein the improvement comprises guide means adjacent to the circumference of said wheel for maintaining said tape in a series of substantially tangential relationships to the circumference of said wheel in the path of rotation of said radial projections, said guide means comprising four rollers which maintain said tape in tangential relation to the circumference of said wheel at three points of tangency spaced approximately 45° about the circumference of said wheel, whereby as said tape is advanced said wheel is rotated by the perforations in said tape engaging said projections on said wheel.
Claim 5
Dependent Claim
202 words
In an apparatus for advancing a multi-layered tape having a plurality of spaced perforations along an edge thereof through a predetermined distance said apparatus being of the type wherein said tape is advanced along a support means by a drive means, and a control means initiates the operation of said drive means to advance said tape and deactivates the operation of said drive means after said tape has advanced through a predetermined distance, and wherein said control means includes a rotatable wheel having radial projections disposed at spaced intervals around its circumference to engage the spaced perforations along the edge of the tape as the tape is advanced, wherein the improvement comprises guide means adjacent to the circumference of said wheel for maintaining said tape in a series of substantially tangential relationships to the circumference of said wheel in the path of rotation of said radial projections, said guide means comprising four rollers which maintain said tape in tangential relation to the circumference of said wheel at three points of tangency spaced approximately 45° about the circumference of said wheel, whereby as said tape is advanced said wheel is rotated by the perforations in said tape engaging said projections on said wheel.
