Abstract
An apparatus (10) for crimping the ends of tubes (44) preparatory to their removal from a tube support structure (46). Accordingly, the apparatus (10) is provided with a plurality of radially spaced serrated members (24A, 24B, 24C and 24D) pivotally mounted within a housing (12). The members (24A, 24B, 24C and 24D) are equipped with rollers (32A, 32B, 32C and 32D) in registry with a retractable cone (34) disposed within the housing (12). An elastic O-ring (38) circumscribes each member (24A, 24B, 24C and 24D).
Claims6
An apparatus for crimping the ends of tubes preparatory of their removal from tube support structures, the apparatus comprising a housing, the housing having a central symmetrical axis, a plurality of members pivotally mounted within the housing and equidistantly disposed about the axis, each member having a crimping end extending beyond the housing, roller means attached to the non-crimping end of each member, a movable cone positioned within the housing and in communication with the rollers, means for extending and retracting the cone, and means for separating the crimping ends from one another so as to position the crimping ends at an angle away from the axis of symmetry of the housing when the cone has been retracted.
