Hinged Belt Splices
 |
| This type is often referred to as 'alligator',
(a U.S. manufacturers trade name) and sometimes
even 'crocodile'! The stated advantage is that as
the fastener is produced from continuous strips
of pressed metal, there is little danger of pieces
of metal detaching themselves from the belt into
the medium carried (which may be food). This can
be a problem with carded hooks but can also happen
to lacing when abrasion is severe. A serious disadvantage
is that metal lacing damages the 'bullnose' on installation
and this can lead to premature failure. Also, if
damage occurs at the side of the splice and because
the lacing is in one piece, all of the lacing can
work loose, that does not happen with carded hooks
as only individual hooks are lost and not the complete
splice. It is Biscor policy to recommend hook rather
than metal lacing fasteners, except for food applications. |
