Abstract
Apparatus for automatically securing borderwires on mattress innersprings, comprising support members for receiving borderwires and a mattress innerspring in stacked, properly oriented relation to one another. A drive mechanism is provided for automatically sequentially advancing the borderwires and the mattress innerspring along the support members to a clip wrapping station where a plurality of clips are simultaneously wrapped on the borderwires and the coils of the mattress innerspring. Control elements are provided for sensing when clips are to be wrapped, and when a predetermined number of clips have been wrapped on each side and each end of borderwires and the mattress innerspring.

Apparatus for automatically securing borderwires on mattress innersprings, comprising:
- mattress innerspring and borderwire support means on which a mattress innerspring and borderwires are positioned in stacked relation;
- alignment means associated with the support means for maintaining a mattress innerspring and borderwires in aligned relation to one another on said support means;
- clip wrapping means positioned adjacent to said support means for simultaneously wrapping a plurality of clips on the borderwires and the coils along the margins of the mattress innerspring to secure the borderwires to the mattress innerspring;
- and control means for sequentially actuating the clip wrapping means whereby the borderwires are successively secured to the coils along the margins of the mattress innerspring.
A method of securing borderwires on the coils of a mattress innerspring, comprising:
- providing support means for receiving borderwires and a mattress innerspring on the support means in a manner to position the mattress innerspring between the borderwires;
- advancing the stacked borderwires and mattress innerspring along the support means to a clip wrapping station positioned adjacent to the support means;
- interrupting the advance of the borderwires and the mattress innerspring at the clip wrapping station;
- simultaneously wrapping a plurality of clips on the borderwires and the coils of the mattress innerspring at the clip wrappping station;
- and continuing the advance of the borderwires and the mattress innerspring along the support means and the interrruption thereof at the clip wrapping station until the borderwires are secured to the coils of the mattress innerspring.
