Definitions
- the feed motor controlling the movement of the strip and cut zipper lengths is set to feed a whole selected zipper length.
- the system cycles through a first cycle involving a feed of a whole zipper length, stop and cut while simultaneously a previously cut to length strip of zipper in the zipper guide track is sealed or tacked to the web material, followed by a second cycle also involving a feed of a whole zipper length, stop and cut while simultaneously a previously cut to length strip of zipper in the zipper guide track is sealed or tacked to the web material and so on.
- a system which enables quick change-overs to different zipper lengths and without necessitating an adjustment of the position of the cutter station relative to the location of the web material and/or a replacement of a zipper guide track for the various cut zipper lengths is highly desirable.
- a method of feeding a selected length of a resiliently flexible plastic profiled recloseable fastener strip from a reel containing a continuous length thereof transversely to an elongate length of web material for securement thereto comprising the steps of: orienting during set up a cutter member of a cutting station a predetermined distance from a longitudinal center line of the web material and orienting an initial first length of the resilient flexible plastic profiled recloseable fastener strip directly from the reel intermittent the cutting station and the center line of the web material; and thereafter advancing a second length of the strip past the cutter station and thence cutting the strip during a time that the strip is not being advanced, followed immediately by a further advancing of a length of the strip equal to the first length past the cutting station and activating a tack or seal of a strip to the web material whereby the initial first length and the second length have a combined length equal to the selected length.
- Figure 1 is a schematic diagram of the zipper attachment or tacking system for performing the method of this invention
- Figure 2 is a schematic diagram illustrating the initial set up positions
- Figure 3 is a schematic diagram of the individual zipper lengths lined up on the zipper guide track following a feed toward the web material of a partial length of zipper material, stop and cut;
- Figure 4 is a view like Figure 3, but illustrating the zipper material having been advanced a partial distance for causing a zipper piece to straddle the center line for the web material and to become tacked or sealed to the web material thereat;
- a zipper installation station 10 includes a spool 11 of extruded resiliently flexible plastic profiled recloseable fastener 12 mounted in a conventional manner to be unwound therefrom by a drive mechanism 13 composed of a pair of mating drive wheels each having an annular groove in the periphery to accommodate the geometry of the recloseable fastener 12.
- the periphery of the drive wheels is also configured to engage each other and be driven at the same speed of rotation by a common servo drive motor 14.
- the material of the recloseable fastener 12 is oriented in a pinched manner between the drive wheels so that when the drive wheels are rotated, the recloseable fastener 12 will be drawn off the spool 11.
- control circuit 16 again causes the drive motor 14 to become activated to effect an advance of the zipper material a partial distance 23 equal in length to the initial first length whereupon the control circuit 16 again halts the drive motor 14 to halt the advance of zipper material to permit a previously cut and advanced strip of zipper material 18A to straddle the center line A of the web material 21 and become sealed or tacked to the stationary web material 21 at this time and as depicted in Figure 4.
- the web material 21 removes the zipper 18A now attached thereto to the position 18C in Figure 2 to empty the guide track section 19 to set up the receipt of a further strip 18B of zipper material in response to the next activation of the drive motor 14 by the control circuit 16.
