Abstract: A novel carpet seaming method and tools for reducing or eliminating seam peaking and profiling is provided. The backing of abutting pieces of carpeting can be reinforced along their respective edges. A staple is supported on an anvil with its legs facing the carpet backing beneath the seam line while a hammer is driven onto the carpet pile and the underlying staple base. The impact of the hammer impales the carpet backing over the legs of the staple, and compresses the staple base against the anvil. The legs can then be forced towards each other to lock the staple in position. The process is repeated along the length of the seam line until a row of staples spaced apart from each other by a predetermined distance and extending from one end of a seam to the other end securely holds the abutting pieces of carpet together to form a seam. After seaming, the carpet may be stretched conventionally and secured to tack strips along the periphery of the area being carpeted.

Abstract: In the course of the upward turning movement of the magazine, the lowermost sheet of staples is taken from the staple cartridge as the feeding member is slidably displaced in the forward direction. Since the thrusting force given by the tension spring is sufficiently larger than the frictional resistance present between the lower surface of the lowermost sheet of staples and the feeding member, each sheet of staples can be more reliably taken from a staple cartridge. As the magazine is turned in an upward direction, a feeding member is displaced in the forward direction by the resilient force of a tension spring, and a contact portion on the feeding member comes in contact with the rear end of the lowermost sheet of staples.
