Abstract
A compression assembly for applying consistent pressure to the material being formed into a continuous tube. The pressure is applied to at least one of a pair of forming rolls of a tube mill during the operation thereof.
Claims8
In a tube mill for the production of continuous seam-welded tubes including a forming roll section having at least one pair of cooperating forming rolls comprising:
- a rear stand;
- a front stand spaced from said rear stand;
- an upper forming roll;
- a lower forming roll cooperating with said upper forming roll;
- an upper spindle supporting said upper forming roll;
- a lower spindle supporting said lower forming roll;
- first bearing means for rotatingly supporting said upper spindle;
- second bearing means for rotatingly supporting said lower spindle;
- and
- means for mounting said first bearing means to said rear stand and said front stand and applying consistent pressure between said upper forming roll and said lower forming roll.
