Appl. No.:

11/986825

Inventors:

Michael E. Dugan - Morrisville PA, US

International Classification:

B65B 53/00
B65B 41/12
B65B 11/04

US Classification:

53587, 53211, 53218, 533892, 53441, 53556

Abstract:

A stretch wrap rope converter and wrapping system includes: a. ) a wrapping apparatus having: (i) a frame for movement of a carriage; (ii) the carriage moveably mounted to the frame and adapted to hold at least one rotatable roll of stretchable film material thereon and being adapted to generate two separate streams of film therefrom; (iii) drive mechanism connected to the carriage; (iv) a stretch wrap rope converter functionally connected to the carriage so as to receive the first stream of film and the second stream of film, the converter having a first orifice for diminishing the first film to create a first rope, and having a second orifice for diminishing the second film to create a second rope, and having rope rotation mechanism so as to rotate the first orifice and the second orifice through an arc in either a reciprocal fashion and/or a circular fashion to cause the first rope and the second rope to move toward, cross and then away from one another; b. ) wrapping target rotation mechanism adapted to rotate either the wrapping apparatus and a wrapping target so the first rope and the second rope engage the wrapping target during rotation.

Abstract:

An environmental testing chamber (10) and thermal cycling method in which, in addition to stressing the device (20) under test with electrical bias (32), elevated temperature (12), pressure (16), and humidity (18) while the device is being monitored (32), a thermoelectric heat pump (26) quickly cycles the temperature of the device by pumping heat from the heat sink (22) mounting the device to another larger heat sink (24).
