A device for spreading apart a pair of tapes such as a pair of slide fastener stringer tapes for enabling attachment of a slider thereto. The spreading device includes a pair of lower grip members movable away from each other on a horizontal base, and a pair of upper grip members vertically aligned with the lower grip members, respectively, and displaceable away from each other. The upper grip members are mounted through a pair of collapsible crossing links on a drive shaft vertically movable toward the base. The tapes are disposed on the lower grip members, respectively, and sandwiched firmly between the upper and lower grip members when the drive shaft is lowered to press the upper grip members against the lower grip members. Continued downward movement of the drive shaft causes the crossing links to collapse, whereupon the upper grip members and hence the lower grip members move away from each other, thereby spreading apart the tapes. |
