Abstract

A listing bead fastening tool has a body that defines a guiding recess shaped to receive a listing bead, and a guide rib extending from the body. The guide rib has a neck and a head that is connected to the body of the tool by the neck. The head has a width to allow it to pass through a retention channel defined by opposing rows of fastener elements extending from a base of a fastener strip to which the listing bead is to be fastened. The guiding recess of the body of the tool defines a listing bead insertion path that is angled with respect to the retention channel. Moving the tool along the retention channel causes the listing bead, which is retained within the guiding recess, to be progressively inserted into the retention channel and retained between the rows of fastener elements.

Claims

1. A method of fastening a listing bead to a fastener strip, the method comprising:

grasping a tool having a body and a guide rib extending from the body, the guide rib having a neck and a head connected to the body by the neck, the body defining a guiding recess shaped to receive the listing bead;

inserting the head of the guide rib into a retention channel defined between opposing rows of fastener elements extending from a base of the fastener strip, with the guiding recess defining a listing bead insertion path angled with respect to the retention channel; and

moving the tool along the retention channel, thereby causing the listing bead retained within the guiding recess to be progressively inserted into the retention channel and retained between the rows of fastener elements.

2. The method of claim 1, further comprising:

prior to moving the tool along the retention channel, inserting the listing bead into the guiding recess.

3. The method of claim 1, wherein inserting the head includes inserting the head into an end of the retention channel.

4. The method of claim 3, wherein a leading portion of the head is tapered to facilitate inserting the head into the end of the retention channel.

5. The method of claim 1, wherein inserting the head includes pressing on the tool to insert the head between the opposing rows of fastener elements.

6. The method of claim 5, wherein a bottom portion of the head is configured as a wedge, along a length of the head, that facilitates inserting the head into the retention channel.

7. The method of claim 1, wherein the head is configured to displace the fastener elements and widen the retention channel as the listing bead is guided into the retention channel.

8. The method of claim 7, wherein the head is further configured to allow the fastener elements to relax and at least partly enclose the listing bead and retain the listing bead in the strip as the tool moves along the fastener strip.

9. The method of claim 1, wherein:

the tool is initially attached to a holding feature at an end of the listing bead; and

the method further comprises detaching the tool from the holding feature prior to moving the tool along the retention channel.

10. The method of claim 9, wherein the holding feature, after being detached from the tool, holds the end of the listing bead against a corresponding end of the fastener strip while the listing bead is progressively inserted into the retention channel.

11. The method of claim 1, wherein:

at least some of the fastener elements include, at a distal end of the respective fasteners, a head portion that extends over the base of the fastener strip; and

the head of the guide rib has a top that contacts a bottom of the respective head portions of at least some of the fastener elements while the head is in the retention channel.

12. The method of claim 11, wherein the fastener elements of only one of the opposing rows of fastener elements includes the head portions that extend over the base of the fastener strip.
