Loveshaw's CF-5 with LD-3SB Increases Throughput 66%

Little David Case Study



CF-5 Semi-Automatic Box Former (operator fed) with LD-3SB Case Sealer

Case Presented: 

An authorized Little David® distributor was asked to visit a national co-packer in Wisconsin to evaluate the benefits of a box former and a case sealer. The company was interested in increasing throughput by eliminating the existing manual process. The operators were hand erecting and bottom taping the box, inserting a partition, placing 4 pouches of product in the box and manually sealing the top of the box.

The equipment proposed needed to be mobile, as it would be moved frequently for use in multiple lines, and operator friendly for frequent case size changes. In coordination with Loveshaw’s Regional Sales Manager, an onsite demonstration of the CF-5 with LD-3 SB extended drive case sealer with three flap folder was conducted at the facility.

Challenges presented:

  • The manual process of erecting and bottom sealing was slow and inefficient.
  • The weight of the product was heavy; 18-20 lbs. per pouch with 4 pouches in a carton. The machine needed to be industrial grade.
  • The top sealing was slow and inefficient.


The CF-5 secured and squared the case; the operator inserted the partition and placed the pouches into the box. The operator was only required to tuck the rear minor flap and the LD-3SB with 3 flap folder folded the remaining flaps then top and bottom sealed the box.

  • The manager noted 66% increased throughput on the line due to the investment in Little David equipment.

To provide maximum use of the machinery in the facility, quick release brackets and castors were installed so the customer could use the LD-3SB on other production lines when not running the pouch line. The combination worked out well for the customer and they are impressed with the robustness and consistency of the Loveshaw system.
