Filed:

Nov 27, 2007

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.

US Classification:

Abstract:

Method and apparatus for looping around a digital transmission line (150) at a predetermined channel unit (172) to test the line from either end of the line. Each channel unit in the line is responsive to a first and a second received control code to perform one of two operations. When the first and second received control codes are both first predetermined control codes from one end of the line, the data channel assumes a state to pass the second received first control code and any subsequently received control codes to the next channel unit. However, when the first and second received control codes are first and second predetermined control codes from the one end of the line, respectively, the data channel unit connects the transmit path from the one line end to the receive path back to the one line end, thus looping back to the digital transmission line. To loop around a line at a predetermined channel unit, a maintenance circuit (152) at one line end applies an individual first predetermined control code for the predetermined channel unit and each of the intermediate channel units followed by the application of a second predetermined control code for the predetermined channel unit. The first channel unit from the end of the line passes the second received first control code and any subsequently received control codes to the next channel.

A channel unit (172) for looping around a digital transmission line (150) in response to first and second received control codes.
