Abstract
Abstract Elongated members, e.g., pipes arriving in succession upon transport device, are subdivided longitudinally at a cutting station by being entrained along a rotary (circular) path intersected by the path of a sawblade, the center of rotation of which lies within the periphery of the circular path but which intersects the latter. The elongated members are retained by clamping devices while they engage the sawblade, the clamping devices releasing the severed portions for further displacement away from the cutting station.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
An apparatus for subdividing a succession of elongated workpieces, comprising transport means including a pair of spaced-apart transport disks rotatable about a common axis and formed along their peripheries with means for entraining said workpieces along a transport path corresponding to a circular arc centered upon said axis, at least one cutting disk rotatable about an axis lying within said path and offset from the axis thereof while intersecting said path to an extent corresponding at least to the thickness of the workpieces entrained along said path.
Claim 2
Independent Claim
87 words
An apparatus for subdividing a succession of elongated workpieces, comprising transport means including a pair of spaced-apart transport disks rotatable about a common axis and formed along their peripheries with means for entraining said workpieces along a transport path corresponding to a circular arc centered upon said axis, at least one cutting disk rotatable about an axis lying within said path and offset from the axis thereof while intersecting said path to an extent corresponding at least to the thickness of the workpieces entrained along said path.
Claim 3
Dependent Claim
62 words
The apparatus defined in claim 1 wherein said cutting disk has a diameter which is less than the diameter of the circular arc described by the outermost portion of said workpieces entrained along said path by about one thickness of the workpiece and the said axes are offset in the downstream direction of movement of said workpieces by about half said thicknesses.
Claim 4
Dependent Claim
61 words
The apparatus defined in claim 2 wherein each of said transport disks is provided along its periphery with a plurality of angularly equispaced claw-shaped retaining members, open in the direction of rotation of said disks and retaining said workpieces against outward movement relative to said transport disks and clamping means radially movable on said transport disks for engagement with said workpieces.
Claim 5
Dependent Claim
16 words
The apparatus deFined in claim 2, further comprising means for adjusting the distance between said axes.
Claim 6
Dependent Claim
21 words
The apparatus defined in claim 2, further comprising means for adjustably shifting said transport and cutting disks along their respective axes.
Claim 7
Dependent Claim
18 words
The apparatus defined in claim 2 wherein said cutting disk is a circular saw having segmented blade portions.
