METAL ROLL HOLDER AND DEVICES WITH SUCH HOLDER Russian patent published in 2014 - IPC B21C47/24 

FIELD: process engineering.

SUBSTANCE: metal roll holder (1, 11, 31) that features, in fact, round cross-section with round perimetre has at least three bearing points (2, 2', 12, 32) arranged to stay in contact with roll (1, 11, 31) in circumferential direction in at least three points (2, 2', 12, 32) at placing said roll (1, 11, 31) on said points (2, 2', 12, 32). Holder comprises two supports (3, 13, 33) whereat mounted is thrust lever (4, 14, 34). Every said lever (4, 14, 34) supports two rollers (2, 12, 32) that makes said support points (2, 12, 32) whereat metal roll (1, 11, 31) is placed. Supports (3, 13, 33) allow adjustment of horizontal spacing there between. Pallet system (30) for storage and transportation of metal rolls (1, 11, 31) comprises pallet (35) incorporating said holder. Metal strip coiler 40 comprises drum 44 and above described holder or above described pallet system (30). Method of sampling roll metal (23) with the help of sampler (10) comprises placing metal roll (1, 11, 31) on holder in sampler (10) or forcing said roll placed on said holder in sampler (10), applying at least one pressure roller (16) to top surface of metal roll (1, 11, 31), exposure of metal roll (1, 11, 31), unwinding said roll (1, 11, 31), separation of metal sample (23), winding said metal roll (1, 11,31) and its strapping. Method of coiling the roll (1, 11, 31) by coiler (30) comprises coiling said metal roll (1, 11, 31) at coiler drum (44) and withdrawing said roll (1, 11, 31) from drum (44) along with holder or pallet system (30).

EFFECT: higher reliability of storage and/or transportation.
