<P>PROBLEM TO BE SOLVED: To provide a toothed belt with attachment for conveyance, which has an enhanced effect for preventing the mixing of an attachment into a conveyance object due to falling of the attachment from a belt body, which results from peeling and cracking of a weld portion of the attachment, by preventing reduction in strength of the weld portion, which results from the peeling and cracking of the weld portion, and further can surely search a broken piece of the attachment mixed into the conveyance object or the fallen attachment. <P>SOLUTION: The toothed belt 100 includes: a belt body 101 having a number of teeth 110 to be meshed with a pulley 140; and an attachment 130 having a weld portion 132 welded to a back surface 120 of the belt body 101. The attachment 130 contains a search object metal 135 which is searchable by a metal detector and uniformly dispersed therein. The whole body of the weld portion 132 is located within a flat portion 121 in which the back surface 120 is planar in a winding portion 101a or within a tooth root forming range S1 of tooth roots 111 of the teeth 110 in the belt longitudinal direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
