Abstract
Abstract Web-supporting roller assembly adapted to support a wide web of sheet material in perfect edge alignment for transport through web-processing equipment. The roller assembly comprises a central shaft, a web-supporting cylindrical tube thereon, flanges adapted to make locking engagement with each end of said tube and with said shaft. The web on said tube is greater in width than said tube and the flanges are greater in diameter than said tube so that the web, in loosely-wound form, can be tapped into perfect edge alignment on the tube by the flanges which can then be locked to said tube and said shaft to secure the web for transport through the apparatus.

Claim 1
Independent Claim
224 words
Web-supporting roller assembly adapted to support a wide web of flexible sheet material in perfect edge alignment for transport through web-processing equipment which comprises a central shaft, a web-supporting tube on said shaft, and flanges slidable on said shaft at each end of said tube, each said flange comprising a shaft collar section provided with locking means adapted to secure said collar to said shaft, a flange section adapted to engage the edge of the web on said tube, and at least one projection extending outwardly from said flange section to engage said web-supporting tube, said projection extending at least one-eighth inch from said flange section, whereby a web of flexible sheet material which is at least one-fourth inch wider than said tube can be wound on said tube and tapped into perfect edge alignment by said flange sections and said tube can be centered beneath said web and secured to said flanges by means of said projection which engages the extremities of said tube whereby the edges of said web are engaged only by said flange sections and said tube is engaged only by the projection extending from said flange sections and is maintained spaced from each said flange section by said projection to prevent the edges of the web fRom becoming lodged between the extremities of said tube and said flange sections.

Web-supporting roller assembly adapted to support a wide web of flexible sheet material in perfect edge alignment for transport through web-processing equipment which comprises a central shaft, a web-supporting tube on said shaft, and flanges slidable on said shaft at each end of said tube, each said flange comprising a shaft collar section provided with locking means adapted to secure said collar to said shaft, a flange section adapted to engage the edge of the web on said tube, and at least one projection extending outwardly from said flange section to engage said web-supporting tube, said projection extending at least one-eighth inch from said flange section, whereby a web of flexible sheet material which is at least one-fourth inch wider than said tube can be wound on said tube and tapped into perfect edge alignment by said flange sections and said tube can be centered beneath said web and secured to said flanges by means of said projection which engages the extremities of said tube whereby the edges of said web are engaged only by said flange sections and said tube is engaged only by the projection extending from said flange sections and is maintained spaced from each said flange section by said projection to prevent the edges of the web fRom becoming lodged between the extremities of said tube and said flange sections.
Claim 3
Dependent Claim
16 words
An assembly according to claim 1 in which said projections on said flanges comprise individual pins.
Claim 4
Dependent Claim
77 words
An assembly according to claim 2 in which said flanges comprise separable flange sections and collar sections, and said projections comprise individual pins, the said pins being mounted on said collar sections and the flange sections being provided with openings through which said pins extend into engagement with said tube when the flange sections are in engagement with the ends of the web on the tube and the shaft collar sections are positioned against the flange sections.
Claim 5
Dependent Claim
74 words
An assembly according to claim 1 in which said web-supporting tube is provided with slots at each end thereof and the projections on each flange comprise individual pins which enter said slots and engage the area of said tube adjacent said slots, said pins being sufficiently long that the ends of said tube are spaced from said flange sections by at least one-eighth inch when said pins are in engagement with said notch areas.
Claim 6
Dependent Claim
23 words
An assembly according to claim 1 in which said web comprises a paper web carrying a pattern imaged thereon with hectograph duplicating composition.
