between interconnections on adjacent protrusions such technique will not work well with a ductile material such as copper as shown in fig2 strip 110 can be stored as a roll 150 in order to facilitate dispensing of individual clips 112 from strip 110 for example roll 150 can be incorporated into a rotary unwind apparatus of a clip dispensing machine that has opposed cutting edges that are driven together to co act and sever individual clips 112 from strip 110 of roll 150 fig3 illustrates an enlarged detailed view of a selected portion of strip 110 showing a plurality of adjacently formed clips 112 fig4 further illustrates such construction taken along section line 4 4 of fig3 as shown in fig3 strip 110 is formed from a single continuous piece of material such as polypropylene or some other previously mentioned suitable material one technique involves cutting strip 110 from a relatively thin sheet of material another technique involves stamping machining or laser cutting strip 110 from a sheet of material other techniques involve cutting strip 110 between a pair of intermeshing rotary cutting dies in the forming process individual clips 112 are contiguously joined together by way of a narrowed strip isthmus or web 152 each strip 152 is provided along a central or medial portion of strip 110 and a pair of laterally positioned slots 154 and 156 are provided.
