ABSTRACT:
This invention pertains to pins carried by and in a retainer head member with the pins actuated when and as the head member and an associated contact member reaches the outermost portion of a paperboard member whereat the pins are caused to move obliquely to this surface and penetrate the paperboard sufficiently to engage and retain the paperboard. These pin ends by latch members are maintained in the desired penetrating position during transfer. This latch is actuated to release the projected pins when transfer is completed. The paperboard is conventionally of corrugated paperboard construction and the extent of pin end protrusion is carefully controlled so that the pin ends in the penetrating position do not protrude and penetrate the rear panel or wall of the paperboard so that only one penetrated paperboard member is transferred. The embodiments shown are adapted for use with paperboard which is not supple or flexible as is cloth or leather. The contacting member is disposed to establish and engage the outer surface of the paperboard member and the latch member is automatic in its operation during penetration and transfer. The latch is actuated to an open and release condition at the end of the transfer motion.
