SYSTEMS AND METHODS FOR DISPENSING POLYMER FASTENERS

摘要

A dispensing device (100) is configured to dispense polymer fasteners from a strand of oriented shape memory polymer configured to expand laterally and contract longitudinally when heated. The dispensing device includes a strand dispenser (101) arranged to dispense the strand. A strand metering mechanism (102) is operable in conjunction with the strand dispenser to dispense a predetermined length of the strand. A cutting mechanism (103) is configured to cut the strand to form a polymer fastener of predetermined length.
