The invention is a placing boom comprising a plurality of boom sections connected together in an articulated arrangement. A pipeline is carried by the boom sections, wherein the pipeline is disposed inside at least one of the boom sections. of said cutting mat is secured by contacting said locking wedge and a wall of said channel, and and said cutting mat are releasably secured to said rotary anvil by friction forces such that when a select one of said opposing first and second flanges of said cutting mat is released from sad channel, both said cutting mat and said lockup device are releasable from said rotary anvil. 6. The lockup device according to claim 5, wherein said locking wedge is positioned on said base closer to said first axial edge than said second axial edge. 7. The lockup device according to claim 5, wherein said locking wedge has a cross section comprising: a leg portion extending from said base; a pair of opposite, angularly outward extending locking surfaces projecting from said leg portion; and, a pair of guide surfaces, each guide surface extending from a respective one of said locking surfaces. 8. The lockup device according to claim 7, wherein said pair of guide surfaces are substantially inverted "V" shaped, each guide surface extending from said respective one of said locking surfaces and joining together at a common point. 9. The lockup device according to claim 7, wherein said locking surfaces are arcuate. 10. The lockup device according to claim 7, wherein said locking surfaces are knurled. 11. The lockup device according to claim 5, wherein the thickness of said sidewall is non-uniform. 12. The lockup device according to claim 5, wherein: a first locking area is defined between said sidewall and said locking wedge; and, a second locking area is defined between said locking wedge and said second axial edge of said base portion, wherein said lockup device is insertable within said channel of said rotary anvil and arranged to secure said cutting mat to said rotary anvil by frictionally holding said first flange of said cutting mat within said first locking area and frictionally holding said second flange of said cutting mat within said second locking area such that said second flange presses at least partially against a wall of said channel. 13. The lockup device according to claim 12, wherein said lockup device is arranged such that when said lockup device is inserted within said channel and said opposing first and second flanges are received by said lockup device, said second flange is releasable from said second locking area and said lockup device is removable from said channel with said first flange remaining at least partially secured within said first locking area. 14. The lockup device according to claim 5, wherein: said channel comprises first and second channel walls and a channel floor; and, said base portion and said sidewall are arranged such that when said lockup device is inserted within said channel, and said opposing first and second flanges are received by said lockup device, said lockup device and said cutting mat are secured to said rotary anvil by frictional forces between said base portion and said channel floor, said side wall and said first channel wall, and said second flange and said second channel wall. 15. A rotary anvil construction comprising: a rotary anvil having a generally cylindrical surface and a channel axially disposed on said cylindrical surface, said channel comprising first and second channel walls projecting inward from said cylindrical surface; a lockup device in said channel and held therein by frictional forces, said lockup device comprising: a base portion having first and second axial edges, and first and second transverse edges; a sidewall projecting from said first axial edge of said base arranged such that when said lockup device is inserted in said channel, said sidewall is juxtaposed said first channel wall; and, a locking wedge projecting from said base; and, a cutting mat having a first end terminating in a first flange, and a second end opposite said first end terminating in a second flange, said cutting mat being wrapped around said cylindrical surface of said rotary anvil such that said first flange is received in, and secured by said locking wedge and said sidewall, said second flange is received in, and secured by said locking wedge and said second channel wall, and said lockup device and said cutting mat are frictionally secured to said rotary anvil. 16. A rotary anvil construction according to claim 15, wherein said cutting mat comprises a polyurethane material. 17. A rotary anvil construction according to claim 15, wherein said first flange is received between said locking wedge and said sidewall such that, upon removing said cutting mat from said rotary anvil, said lockup device releases from said channel, and said first flange remains at least partially secured between said locking wedge and said sidewall. 18. A rotary anvil construction according to claim 15, further comprising a plurality of lockup devices and corresponding cutting mats axially disposed within said channel, said plurality of lockup devices and cutting mats arranged such that any one of said cutting mats may be released from said rotary anvil without disturbing the remainder of said plurality of cutting mats. 19. A rotary anvil construction according to claim 15, wherein said locking wedge is positioned on said base closer to said first axial edge than said second axial edge, and said second flange is thicker than said first flange such that when said cutting mat and said lockup device are installed in said channel of said rotary anvil, said first flange is compressed between said locking wedge and said sidewall, and said second flange is compressed against said locking wedge and said second channel wall. 20. A rotary anvil construction according to claim 15, wherein: said locking wedge has a cross section comprising a leg portion extending from said base, a pair of opposite, angularly outward extending locking surfaces projecting from said leg portion, and a pair of guide surfaces, each guide surface extending from a respective one of said locking surfaces and joining together at a common point defining a substantially inverted "V" shape; and, said first and second flanges of said cutting mat comprise holding surfaces complimentary to said locking surfaces of said locking wedge, and aligning surfaces complimentary to said guiding surfaces of said locking wedge. 21. A rotary anvil construction according to claim 20, wherein said locking surfaces are arcuate. 22. The locking mechanism according to claim 20, wherein said locking surfaces are knurled. 23. The locking mechanism according to claim 15, wherein the thickness of said sidewall is non-uniform. 24. A rotary anvil construction according to claim 15, wherein said cutting mat further comprises an area of relief recessed into the back of said cutting mat, adjacent each said first and second flanges. 25. A lockup device for a rotary anvil comprising: a base portion having first and second axial edges, and first and second transverse edges; a sidewall projecting from said first axial edge of said base; and, a locking wedge projecting from said base spaced closer to said first axial edge than said second axial edge, said locking wedge defining a first locking area between said sidewall and said locking wedge, and a second locking area between said lacking wedge and said second axial edge of said base, and wherein said locking wedge has a cross section comprising: a leg portion extending from said base; a pair of opposite, angularly outward extending locking surfaces projecting from said leg portion; and, a pair of guide surfaces extending from a respective one of said locking surfaces to join together at a common point, wherein said lockup device is arranged to fit into a channel of a rotary anvil and receive a first flange of a cutting mat compressed into said first locking area, and receive a second flange of said cutting mat compressed into said second locking area so as to press between said locking wedge of said lockup device and
