Abstract
A belt installation device for installing a belt onto a paper machine, pulp machine or board machine, has a first area (4) with an attaching point (5) for attaching the belt installation device to a pulling member, a second area (6) with at least one aperture (7, 7a, 7b, 7c, 7d) for fastening the belt installation device (1) removably to a belt, and a central area (8) between the first area (4) and the second area (6), wherein a pull strength of the attaching point is at least 300 kgf and equal or less than 900 kgf. The belt installation device is bendable between a straight form and a curved form having a radius of curvature of 800 mm. This invention further relates to an installation arrangement and installing method for installing a belt onto a paper, pulp or board machine.
Claims14
A belt installation arrangement comprising at least two belt installation devices for installing a tubular belt onto a paper machine, pulp machine or board machine, each belt installation device comprising:
- a flexible body having a first segment having portions defining an attaching point for attaching the belt installation device to a pulling member;
- a second segment of the body which is wider than the first segment and which has portions defining at least one aperture for fastening the belt installation device removably to a belt, and
- a central segment of the body positioned between and connecting the first segment and the second segment, wherein when the pulling member is attached to the first segment attaching point, the pulling member applies a force of a selected pull strength between at least 300 kgf to 900 kgf without breaking the first segment at the attaching point, and wherein a force of greater than the selected pull strength applied to the first segment by the pulling member will break the first segment at the attaching point such that the pulling member detaches from the first segment, and wherein a bending axis is defined extending from the first segment to the second segment, and the body is bendable about the bending axis to have a radius of 800 mm;
- and
- wherein the at least two belt installation devices are positionable symmetrically around a perimeter of the tubular belt and are attached to attaching points of the tubular belt at a mill side of the paper machine, pulp machine or board machine, for installation of the tubular belt by pulling the tubular belt in a cross-machine direction.
