High Speed and Exceptional Design Lead to 80% Increased Throughput

Little David Case Study



LDX-RTB Semi-Automatic, High Speed, Random Case Sealer with Pneumatic Head (Operator-Fed) 


We were invited by an authorized Little David® distributor to visit an internet fulfillment center located in Pennsylvania who was interested in increasing throughput and eliminating box jams. The facility was shipping in the range of 600 to 6,000 random size boxes per day.

Their existing competitor taper was running at 80 fpm. Due to the infeed design of the taper, it would often jam causing severe bottlenecks in the packaging line. The company needed to have an experienced operator running the finicky machine to decrease the incidents of it jamming. The frequent jams and the slow speed caused shipping deadline challenges.


Within minutes of the onsite demonstration, it was obvious the LDX-RTB with High Speed Option (155 fpm) would solve their challenges. The manager asked to keep the LDX-RTB on site for a few days and Loveshaw agreed. Multiple operators noted no issues with the machine and were amazed by “how fast and smooth the RTB runs.”

The purchase of the LDX-RTB case sealer with pneumatic head has resulted in:

  • Increased throughput of 80%
  • Virtual elimination of box jams:
    • the smooth delivery of boxes into the machine due to the durable guarded metal height sensing paddle which features a non-mechanical proximity switch and no springs
    • the pneumatic head with patented light-touch cartridge glides over the case, instead of crushing the case

Interested in an onsite demonstration of the LDX-RTB? Loveshaw offers readily available onsite demonstrations throughout the continental US upon request.
