Abstract

Abstract A wrapping apparatus for wrapping a strip material about an elongated member on a suspension type bridge having a guide member mounted above said elongated member is disclosed. The wrapping apparatus has a torque stay frame depending from the guide member and movable on the guide member. A frame is secured to the torque stay frame and is movable on the elongated member. A flyer is rotatable with respect to the frame and the elongated member. A strip material feeding means is rotatably mounted on the flyer and has the free end of the strip material attached to the elongated member so that rotation of the flyer relative to the elongated member wraps the strip material about the elongated member. A longitudinal drive means has a drum rotatable on the frame and a rope member is connected to the drum and to the elongated member. Connecting means are between the longitudinal drive means and the flyer so that rotation of the flyer causes rotation of the drum with attendant winding of the rope member on the drum and resultant predetermined linear movement of the wrapping apparatus with respect to the elongated member for each revolution of the flyer with respect to the elongated member.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 202 words
A wrapping apparatus for wrapping a strip material about an elongated member on a suspension type bridge, said bridge having a guide member mounted above said elongated member, said wrapping apparatus having: a. a torque stay frame depending from said guide member and movable on said guide member; b. a frame secured to said torque stay frame and movable on said elongated member; c. a flyer rotatable with respect to said frame and said elongated member; d. strip material feeding means rotatably mounted on said flyer and having the free end of said strip material attached to said elongated member so that relative rotation between said flyer and said elongated member wraps said strip material about said elongated member; e. longitudinal drive means having a drum rotatable on said frame and a rope member connected to said drum and to said elongated member; f. connecting means between said longitudinal drive means and said flyer so that rotation of said flyer causes rotation of said drum with attendant winding of said rope member on said drum and resultant predetermined linear movement of said wrapping aPparatus with respect to said elongated member for each revolution of said flyer with respect to said elongated member.
Claim 2
Dependent Claim 202 words
A wrapping apparatus for wrapping a strip material about an elongated member on a suspension type bridge, said bridge having a guide member mounted above said elongated member, said wrapping apparatus having: a. a torque stay frame depending from said guide member and movable on said guide member; b. a frame secured to said torque stay frame and movable on said elongated member; c. a flyer rotatable with respect to said frame and said elongated member; d. strip material feeding means rotatably mounted on said flyer and having the free end of said strip material attached to said elongated member so that relative rotation between said flyer and said elongated member wraps said strip material about said elongated member; e. longitudinal drive means having a drum rotatable on said frame and a rope member connected to said drum and to said elongated member; f. connecting means between said longitudinal drive means and said flyer so that rotation of said flyer causes rotation of said drum with attendant winding of said rope member on said drum and resultant predetermined linear movement of said wrapping aPparatus with respect to said elongated member for each revolution of said flyer with respect to said elongated member.
Claim 3
Dependent Claim 20 words
The wrapping apparatus recited in claim 1 wherein said frame has a plurality of rollers engageable with said elongated member.
Claim 4
Dependent Claim 26 words
The wrapping apparatus recited in claim 2 wherein one roller of said rollers has biasing means for adjustably positioning said one roller against said elongated member.
Claim 5

Claim 13
Dependent Claim 34 words
The wrapping apparatus recited in claim 1 and having strip tension means connected to said strip material feeding means for applying a predetermined tension to said strip material feeding means and said strip material.
Claim 14
Dependent Claim 47 words
The wrapping apparatus recited in claim 12 wherein said strip tensioning means has: a. a friction brake engageable with said strip material feeding means; and b. biasing means associated with with said fricion brake for applying a retarding force between said friction brake and said biasing means.
Claim 15
Dependent Claim 36 words
The wrapping apparatus recited in claim 1 and having spacer means on said drum for increasing the diameter of said drum thereby varying the linear velocity of said wrapping apparatus for each revolution of said flyer.
Claim 16
Dependent Claim 60 words
The wrapping apparatus recited in claim 1 and having positioning means on said frame for supporting said strip material feeding means and for varying the angular position of said strip material feeding means with respect to the longitudinal axis of said elongated member to provide a predetermined angle of incidence of said strip material with respect to said elongated member.
