Abstract
Abstract A method and apparatus for securely fastening a band to at least one object such as a refractory nozzle for a molten steel pouring ladle. A tab is affixed to the end of a band and the band is wrapped around the object so as to divide the band into a wrapped section and an unwrapped section, a first portion of the wrapped section overlying the tab and a second portion of the wrapped section. While the tab is restrained against movement in one direction around the object, the unwrapped section of the band is pulled so as to tighten the band around the object. While the band is held in this position, automatic welding means indirectly pressure spotweld the tab and the first and second portions of the wrapped section together.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
143 words
A method of securing a band to at least one object comprising the steps of: affixing a tab to one end of said band; holding said object in place; wrapping said band with said tab affixed thereto around said object to provide a wrapped section including said one end of said band which has said tab affixed thereto and an unwrapped section of said band, a first portion of said wrapped section of said band overlapping both said one end of said band and said tab; restraining said tab against movement in a first direction around said object; pulling said unwrapped section of said band to pull said wrapped section in said first direction to tighten said band around said object; and welding together said first portion of said wrapped section of said band, said one end of said band and said tab.
Claim 2
Independent Claim
143 words
A method of securing a band to at least one object comprising the steps of: affixing a tab to one end of said band; holding said object in place; wrapping said band with said tab affixed thereto around said object to provide a wrapped section including said one end of said band which has said tab affixed thereto and an unwrapped section of said band, a first portion of said wrapped section of said band overlapping both said one end of said band and said tab; restraining said tab against movement in a first direction around said object; pulling said unwrapped section of said band to pull said wrapped section in said first direction to tighten said band around said object; and welding together said first portion of said wrapped section of said band, said one end of said band and said tab.
Claim 3
Dependent Claim
25 words
The method of claim 1 including after the steP of welding, the step of severing said unwrapped section of said band from said wrapped section.
Claim 4
Dependent Claim
60 words
The method of claim 2 wherein the step of restraining said tab against movement in said first direction comprises: rigidly, temporarily positioning a tab restraining means on the surface of said object, said tab restraining means permitting said band to pass freely between said tab restraining means and the wall of said object but preventing said tab from passing therebetween.
Claim 5
Dependent Claim
60 words
The method of claim 3 wherein the step of pulling said band comprises: guiding said unwrapped section of said band between a drive roller and an idler roller; moving one of said rollers toward the other of said rollers to clamp said band therebetween; and rotating said drive roller to move said unwrapped section of said band between said rollers.
Claim 6
Dependent Claim
41 words
The method of claim 1 wherein the step of welding together said first portion of said wrapped section, said one end of said band and said tab comprises indirectly pressure spotwelding said first portion, said one end and said tab together.
Claim 7
Independent Claim
150 words
An apparatus for tightly wrapping and securely fastening a band wrapped around at least one object, the band having a tab affixed to one end thereof and being divided into a wrapped section which is wrapped around the object and an unwrapped section, the wrapped section of the band having a first portion which overlaps both the tab and the one end of the band having the tab affixed thereto, the apparatus comprising: object holding means for holding the object in place; tab restraining means engagable with said tab for restraining said tab from movement in a first direction around the object; pulling means engagable with the unwrapped section of said band for pulling said wrapped section in said first direction to tighten said band around the object; and welding means for welding together the first portion of said wrapped section, said one end of said band and said tab.
Claim 8
Independent Claim
150 words
An apparatus for tightly wrapping and securely fastening a band wrapped around at least one object, the band having a tab affixed to one end thereof and being divided into a wrapped section which is wrapped around the object and an unwrapped section, the wrapped section of the band having a first portion which overlaps both the tab and the one end of the band having the tab affixed thereto, the apparatus comprising: object holding means for holding the object in place; tab restraining means engagable with said tab for restraining said tab from movement in a first direction around the object; pulling means engagable with the unwrapped section of said band for pulling said wrapped section in said first direction to tighten said band around the object; and welding means for welding together the first portion of said wrapped section, said one end of said band and said tab.
Claim 9
Dependent Claim
46 words
The apparatus of claim 6 further including a platform on which said tab restraining means, said pulling means and said welding means are fixedly supported; and platform support means for supporting said platform for relative longitudinal movement and relative lateral movement with respect to the object.
Claim 10
Dependent Claim
36 words
The apparatus of claim 7 further including means for laterally positioning and holding in place said platform with respect to the object to properly position said tab restraining means, said pulling means and said welding means.
Claim 11
Dependent Claim
70 words
The apparatus of claim 8 wherein said platform support means comprises a longitudinally extending support column having a longitudinal axis which supports said platform for lateral pivotal movement about said longitudinal axis and for longitudinal movement therealong; and wherein said lateral positioning means comprises a cylinder means mounted on said platform having a piston rod engagable with the object for pivoting said platform into position and to hold it thereinplace.
Claim 12
Dependent Claim
66 words
The apparatus of claim 9 wherein said tab restraining means comprises a guide member and a support member for supporting said guide member from said platform, said guide member being adapted to contact the surface of the object when said platform is pivoted into position to permit said band to pass between said guide member and the object and to prevent said tab from passing therebetween.
Claim 13
Dependent Claim
109 words
The apparatus of claim 10 wherein said cylinder means is mounted on said platform substantially opposed to said guide member and on the opposite side of the object from said guide member; wherein said guide member has longitudinally spaced feet for contacting the object, the longitudinal spacing between said feet being greater than the longitudinal dimension of the wrapped section of said band but less than the longitudinal dimension of the tab affixed to said band, and wherein said guide member is pivotably mounted on said support member to pivot about a longitudinal axis when the object is moved into cOntact with said guide member by said cylinder means.
Claim 14
Dependent Claim
53 words
The apparatus of claim 11 wherein said pulling means comprises: a pair of rollers mounted for rotational movement about parallel axes and adapted to engage the unwrapped section of said band therebetween; and means for rotating one of said rollers to pull said unwrapped section of said band through and between said rollers.
Claim 15
Dependent Claim
67 words
The apparatus of claim 12 wherein said welding means comprises at least two welding guns, one of which has a dummy electrode and the other of which has a welding electrode, said two electrodes being mounted on said platform for movement into contact with said tab and said band respectively to indirectly pressure spotweld together said first portion, said one end of said band, and said tab.
