    Abstract: A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.

    Abstract translation: 纸杯的底部通过将冲头推向纸板网而形成，以将纸幅推向相对于从卷筒纸切出圆形杯底部坯料的切割边缘。 冲头保持在向前状态，以将坯件的外周部分不可移动地抵靠套筒的表面。 相对于坯料的中心部分进行往复式拉伸，以将中心部分推入套筒的圆形开口中同时保持夹紧力，从而使坯料的中心部分变得拉伸。 然后逐渐释放夹紧力，以允许外周部分进入开口并弯曲成形成以大致直角延伸的唇缘。 唇部在形成于拉伸部和开口部的表面之间的间隙内被压缩。 由于坯料的拉伸，唇部中形成的褶只是以非褶皱状态变平的微细褶皱的形式。

    Abstract: An improved method and apparatus for individually wrapping drinking straws applies a web of wrapping material to sequentially supplied straws while providing separately: (i) a crimping station for the wrapping material which secures it about the straws by providing longitudinal and transverse crimps and (ii) a cutting station for separating the wrapped straws. The discrete locations of the crimping and cutting stations enables faster and more reliable production by separating operations, which reduces the amount of mechanical interaction between dies at a single location, thereby reducing die bounce. Speed increases of 15-20 percent are readily achieved.

The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve.

The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.
